ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 7 of 42 1.3 Block diagram Figure 1: Block diagram of ANNA-B112 The ANNA-B112 SiP module has an integrated antenna mounted on the substrate. The RF signal pin can either be connected directly to the adjacent antenna pin and use the internal antenna or routed to an external antenna or antenna connector. The module does not have its own low power oscillator (LPO) and depending on the power supply requirement, you could connect an external LPO crystal or oscillator. An integrated DC/DC converter is used for higher efficiency under heavy load situations. See section 2.1.1 for more information. 1.4 Product description Item ANNA-B112 Bluetooth version 5.0 Band support 2.4 GHz, 40 channels Typical conducted output power +4 dBm Max radiated output power (EIRP) 6.5 dBm Sensitivity (conducted) -91 dBm Best sensitivity (EIRP) -93.5 dBm Data rates 1 and 2 Mbps GFSK Module size 6.5 x 6.5 x 1.2 mm Table 2: ANNA-B112 characteristics summary 32 MHz 32.768 kHz
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 8 of 42 1.5 Software options The integrated application processor of the ANNA-B112 module is an Arm Cortex-M4 with FPU that has 512 kB flash memory and 64 kB RAM. The software structure of any program running on the module can be broken down into the following components:  Radio stack  Bootloader (optional)  Application ☞ More information on each option can be found in the ANNA-B112 System Integration Manual [1]. 1.5.1 u-blox connectivity software The ANNA-B1 module is preflashed with u-blox connectivity software. The u-blox connectivity software enables the use of the u-blox Low Energy Serial Port Service, controlled by AT commands over the UART interface. You can configure ANNA-B112 modules through u-blox s-center software or by using the AT commands. The s-center evaluation software can be downloaded from the u-blox website and is available free of charge. More information on the features and capabilities of the u-blox Low Energy Serial Port Service and how to use this can be found in the ANNA-B112 Getting Started Guide [3] and the u-blox Short Range AT commands manual [2]. 1.5.2 Open CPU A custom application can be embedded in the ANNA-B112 module. The supported development environments are described below. Nordic SDK The Nordic nRF5 SDK provides a rich and well tested software development environment for nRF52-based devices. It includes a broad selection of drivers, libraries, and example applications. Radio Stack Nordic S132 SoftDevice Figure 2: ANNA-B112 software structure and available software options
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 9 of 42 Arm Mbed OS Arm Mbed OS is an open source embedded operating system designed specifically for the "things" in the Internet of Things. It includes all features to develop a connected product, including security, connectivity, an RTOS, and drivers for sensors and I/O devices. The u-blox ANNA-B112 module fully supports Mbed OS 5. Wirepas Mesh stack The ANNA-B112 modules can also be used together with the Wirepas Mesh stack. This will enable the ANNA-B1 module to be used in a large-scale mesh environment. The Wirepas mesh stack is a third party licensed software from Wirepas. For more information about the Wirepas mesh stack, contact the u-blox support for your area as listed in the Contact section or Wirepas directly. 1.6 Bluetooth device address Each ANNA-B1 module is preprogrammed with a unique 48-bit Bluetooth device address.
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 10 of 42 2 Interfaces 2.1 Power management 2.1.1 Module supply input (VCC) The ANNA-B112 uses an integrated step-down converter to transform the supply voltage presented at the VCC pin into a stable system voltage. Due to this, the ANNA-B112 modules are compatible for use in battery powered designs without the use of an additional voltage converter. You can choose one of the following two on-board voltage converter options:  A low-dropout (LDO) converter  A DC/DC buck converter Normally, the module will automatically switch between these options depending on the current consumption. Under high loads such as when the radio is active, the DC/DC converter is more efficient, while the LDO converter is more efficient in the power saving modes. 2.2 RF antenna interfaces 2.2.1 2.4 GHz Bluetooth low energy (ANT) The ANNA-B112 2.4 GHz antenna interface can be used in one of the following two ways as mentioned below: 1. With an external antenna or antenna connector: The ANNA-B112 modules provide an antenna pin (ANT) with a nominal characteristic impedance of 50 Ω. This pin can be connected to a carrier board antenna or antenna connector using a controlled impedance trace. See the ANNA-B112 System Integration Manual [1] for more information. OR 2. With the internal antenna: The ANNA-B112 module has an onboard integrated antenna. To use this antenna, the internal antenna pin (ANT_INT) has to be connected directly to the ANT pin (adjacent to the ANT_INT pin). The ANT pins shall not be connected anywhere else in this case and no additional antenna or RF component is needed. Also the connection to the ANT_PCB, ANT_GND1 and ANT_GND2 pins need to be designed correctly see the ANNA-B112 System Integration Manual [1] for more information. 2.2.2 Near Field Communication (NFC) The ANNA-B112 modules include a Near Field Communication interface, capable of operating as a 13.56 MHz NFC tag at a bit rate of 106 kbps. As an NFC tag, data can be read from or written to the ANNA-B112 modules using an NFC reader; however the ANNA-B112 modules are not capable of reading other tags or initiating NFC communications. Two pins are available for connecting to an external NFC antenna: NFC1 and NFC2. See the ANNA-B112 System Integration Manual [1] for more information and NFC antenna design considerations. 2.3 Low Power Oscillator interface During standby mode, the module needs a 32.768 kHz clock source (accuracy +/- 250 ppm). Several clock options are available for the ANNA-B112 module as specified in Table 3: Table 3: Supported low power clock sources for ANNA-B112 Source Current consumption Comment External 32.768kHz crystal 300 nA Connected to the XL1 and XL2 pins (see chapter 3). Internal RC oscillator 620 nA + calibration Needs recalibration every 8 s External 32.768 kHz clock signal - Connected to the XL1 pin (see chapter 3).
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 11 of 42 See the ANNA-B112 System Integration Manual [1] for more information about connecting an external 32.768 kHz clock source. 2.4 System functions The ANNA-B112 modules are power efficient devices capable of operating in different power saving modes and configurations. Different sections of the module can be powered off when not needed and complex wake up events can be generated from different external and internal inputs. The radio part of the module operates independently from the CPU. The two main power saving modes are:  Standby mode  Sleep mode Depending on the application, the module should spend most of its time in sleep mode to conserve battery life. 2.4.1 Module power-on ANNA-B112 modules can be switched on in one of the following ways and this will cause the module to reboot:  Rising edge on the VCC pin to a valid supply voltage  Issuing a reset of the module A wake up event from sleep mode to active mode can be issued by:  Changing the state of any digital I/O pin, may be enabled /disabled for each pin. If waking up from standby mode, an event can also be issued by:  The on-board Real Time Counter (RTC)  A programmable digital or analog sensor event. For example, rising voltage level on an analog comparator pin 2.4.2 Module power-off There is no dedicated pin to power off the ANNA-B112 modules. You can configure any GPIO pin to enter or exit the sleep mode (see section 2.4.4), which essentially powers down the module. An under-voltage (brown-out) shutdown occurs on ANNA-B112 modules when the VCC supply drops below the operating range minimum limit. If this occurs, it is not possible to store the current parameter settings in the module’s non-volatile memory. An over-temperature and under-temperature shutdown can be enabled on ANNA-B112 modules, and is initiated if the temperature measured within the module is outside operating conditions. The temperature is measured by an integrated temperature sensor in the radio chip. For more details see the ANNA-B112 System Integration Manual [1]. 2.4.3 Standby mode Standby mode is one of the power saving modes in ANNA-B112 modules that essentially powers down the module but keeps the system RAM intact and allows for a few low power digital interfaces (including SPI) and analog functions to run continuously. It also allows for complex, autonomous power-up events including periodic RTC events and radio events. The following events can be used to bring the module out of the standby mode:  External wake-up events  Internal wake-up events from RTC, radio, NFC and so on  Analog or digital sensor event (programmable voltage level or edge detection)
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 12 of 42 ☞ During standby mode, the module needs a 32.768 kHz clock source. See section 2.3 for more information about connecting an external 32.768 kHz clock source. 2.4.4 Sleep mode Sleep mode is the deepest power saving mode of ANNA-B112 modules. During sleep mode, all functionality is stopped to ensure minimum power consumption. The module needs an external event in order to wake up from sleep mode. The following events can be used to wake up the module out of the sleep mode:  External event on a digital pin  External event on a low power comparator pin  Detection of NFC field When using the u-blox connectivity software, the module can be manually switched on or off with proper storage of current settings using the UART DSR pin. The module can be programmed to latch the digital values present at its GPIO pins during sleep. The module will keep the values latched, and a change of state on any of these pins will trigger a wake up to active mode. The module will always reboot after waking up from the sleep mode; however different sections of the RAM can be configured to remain intact during and after going into the sleep mode. 2.4.5 Module reset ANNA-B112 modules can be reset in one of the following ways:  Low level on the RESET_N input pin, normally high with internal pull-up. This causes an “external” or “hardware” reset of the module. The current parameter settings are not saved in the module’s non-volatile memory and a proper network detach is not performed.  Using the AT+CPWROFF command. This causes an “internal” or “software” reset of the module. The current parameter settings are saved in the module’s non-volatile memory and a proper network detach is performed. 2.4.6 Real Time Counter (RTC) A key system feature available on the module is the Real Time Counter. This counter can generate multiple interrupts and events to the CPU and radio as well as internal and external hardware blocks. These events can be precisely timed ranging from microseconds up to hours, and allows for periodic BLE advertising events etc., without involving the main CPU. The RTC can be operated in power-on and standby modes. ☞ During standby mode, the module needs a 32.768 kHz clock source. See section 2.3 for more information about connecting an external 32.768 kHz clock source. 2.5 Serial interfaces ANNA-B112 modules provide the following serial communication interfaces:  1x UART interface: 4-wire unbalanced asynchronous serial interface used for AT commands interface, data communication and u-blox connectivity software upgrades using the FOAT feature.  3x SPI interfaces: Up to three serial peripheral interfaces can be used simultaneously.  2x I2C interfaces: Inter-Integrated Circuit (I2C) interface for communication with digital sensors. ☞ Radio performance parameters such as sensitivity, may be affected by high frequency on some of the digital I/O with large sink/source current. See low frequency pins in Table 7 for additional information.
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 13 of 42 ☞ All digital interface pins on the module are shared between the digital and analog interfaces and GPIOs. Any function can be assigned to any pin that is not already occupied. 2.5.1 Asynchronous serial interface (UART) The UART interface supports hardware flow control and baud-rates up to 1 Mbps. Other characteristics of the UART interface are listed below:  Data lines (RXD as input, TXD as output) and hardware flow control lines (CTS as input, RTS as output) are provided.  Hardware flow control or no flow control (default) is supported.  Power saving indication available on the hardware flow control output (CTS line): The line is driven to the OFF state when the module is not ready to accept data signals.  Programmable baud-rate generator allows most industry standard rates, as well as non-standard rates up to 1 Mbps.  Frame format configuration: o 8 data bits o Even or no-parity bit o 1 stop bit  Default frame configuration is 8N1, meaning eight (8) data bits, no (N) parity bit, and one (1) stop bit. ☞ Radio performance parameters such as sensitivity, may be affected by high frequency on some of the digital I/O with large sink/source current. See low frequency pins in Table 7 for additional information. 2.5.2 Serial peripheral interface (SPI) ANNA-B112 supports up to 3 Serial Peripheral Interfaces that can operate in both master and slave mode with a maximum serial clock frequency of 8 MHz in both master and slave modes. The SPI interfaces use 4 signals: SCLK, MOSI, MISO and CS. When using the SPI interface in master mode, it is possible to use GPIOs as additional Chip Select (CS) signals to allow addressing of multiple slaves. ☞ Radio performance parameters such as sensitivity, may be affected by high frequency on some of the digital I/O with large sink/source current. See low frequency pins in Table 7 for additional information. 2.5.3 I2C interface The Inter-Integrated Circuit interfaces can be used to transfer or receive data on a 2-wire bus network. The ANNA-B112 modules can operate as both master and slave on the I2C bus using both standard (100 kbps) and fast (400 kbps) transmission speeds. The interface uses the SCL signal to clock instructions and data on the SDL signal. ☞ Radio performance parameters such as sensitivity, may be affected by high frequency on some of the digital I/O with large sink/source current. See low frequency pins in Table 7 for additional information. 2.5.4 I2S interface The Inter-IC Sound (I2S) interface can be used to transfer audio sample streams between ANNA-B112 and external audio devices such as codecs, DACs, and ADCs. It supports original I2S and left or right-aligned interface formats in both master and slave mode. It uses up to 5 signals: Master clock (MCK), Left right clock or Word clock (LRCK), Serial clock (SCK), Serial data in (SDIN) and Serial data out (SDOUT). The Master side of the interface always provides the LRCK and SCK clock signals, but as an addition ANNA-B112 can supply a MCK clock signal in both master and slave mode to provide
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 14 of 42 to external systems that cannot generate their own clock signal. The two data signals - SDIN and SDOUT allow for simultaneous bi-directional audio streaming. The interface supports 8, 16 and 24-bit sample widths with up to 48 kHz sample rate. ☞ Radio performance parameters such as sensitivity, may be affected by high frequency on some of the digital I/O with large sink/source current. See low frequency pins in Table 7. 2.6 GPIO The ANNA-B112 modules are versatile concerning pin-out. If un-configured, there will be 25 GPIO pins in total and no analog or digital interfaces. All digital interfaces or functions must then be allocated to a GPIO pin before use. 8 out of the 25 GPIO pins are analog enabled thus they can have an analog function allocated to them. In addition to the serial interfaces, Table 4 shows the number of digital and analog functions that can be assigned to a GPIO pin. ☞ The pins dedicated to the NFC antenna function (NFC1 and NFC2) will have some limitation when the pins are configured for normal GPIO operation. The pin capacitance will be higher on those, and you can expect some increased leakage current between the two pins if they are used in GPIO mode and are driven to different logical values. To save power, the two pins should always be set to the same logical value whenever entering one of the device power saving modes. See section 4.2.7 for more information.

These waveforms can be used to control motors, dim LEDs and as audio signals, if connected to speakers. Duty-cycle sequences may be stored in RAM to be chained and looped into complex sequences without CPU intervention. Each channel uses a single GPIO pin as output. 2.7 Analog interfaces 8 out of the 25 digital GPIOs can be multiplexed to analog functions. The following analog functions are available for use:  1x 8-channel ADC
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 15 of 42  1x Analog comparator*  1x Low-power analog comparator* *Only one of the comparators can be used simultaneously. 2.7.1 ADC The Analog to Digital Converter (ADC) can sample up to 200 kHz using different inputs as sample triggers. It supports 8/10/12-bit resolution. Any of the 8 analog inputs can be used both as single-ended inputs and as differential pairs for measuring the voltage across them. The ADC supports full 0 V to VCC input range. 2.7.2 Comparator The comparator compares voltages from any analog pin with different references as shown in Table 5. It supports full 0 V to VCC input range and can generate different software events to the rest of the system. 2.7.3 Low power comparator The low-power comparator operates in the same way as the normal comparator, with some reduced functionality. It can be used during sleep mode as a wake up source. 2.7.4 Analog pin options Table 5 shows the supported connections of the analog functions. ☞ An analog pin may not be simultaneously connected to multiple functions.

See section 2.4.5 for detailed information.  If SWITCH_2 is driven low during start up, the UART serial settings are restored to their default values.  SWITCH_2 can be used to open a Bluetooth LE connection with a peripheral device.  If both SWITCH_1 and SWITCH_2 are driven low during start up, the system will enter the bootloader mode.  If both SWITCH_1 and SWITCH_2 are driven low during start up and held low for 10 seconds, the system will exit the bootloader mode and restore all settings to their factory default. 2.8.4 UART signals In addition to the normal RXD, TXD, CTS, and RTS signals, the u-blox connectivity software adds the DSR and DTR pins to the UART interface. Note that they are not used as originally intended, but to control the state of the ANNA module. For example, depending on the current configuration: The DSR pin can be used to:  Enter command mode  Disconnect and/or toggle connectable status  Enable/disable the rest of the UART interface  Enter/wake up from sleep mode The DTR pin can be used to indicate:  The system mode  If the SPS peers are connected  If a Bluetooth LE bonded device is connected  A Bluetooth LE GAP connection ☞ See the u-blox Short Range AT Commands Manual [2] for more information. 2.8.5 IO signals When using the u-blox connectivity software, 11 module pins can be used for manual, digital read/write operations. These pins can be configured as outputs or inputs with or without pull-up/pull-down, using AT commands. For more information, see the u-blox Short Range AT Commands Manual [2]. ☞ In this data sheet, these signals are defined as IO signals to distinguish from the GPIO signals described in section 2.6. The IO signals are used with u-blox connectivity software only and
ANNA-B112 - Data Sheet UBX-18011707 - R03 Contents Page 17 of 42 controlled using AT commands; the GPIO signals, being a hardware functionality, can be used only by writing a custom software application. 2.9 Debug interfaces 2.9.1 SWD The ANNA-B112 series modules provide an SWD interface for flashing and debugging. The SWD interface consists of two pins: SWDCLK and SWDIO. 2.9.2 Trace – Serial Wire Viewer A serial trace option will also be available as an additional pin: SWO. The Serial Wire Output is used to:  Support printf style debugging  Trace OS and application events  Emit diagnostic system information A debugger that supports Serial Wire Viewer (SWV) is required. The trace function can be used only when developing a custom application.

Alternatively, if you use the u-blox connectivity software, refer to the pin-out in section 3.2. A = Analog function capable pin LF = Low Frequency, low drive I/O only Signals that are highlighted in red are locked to a specific pin, the grey pins are GND pins. Figure 3: ANNA-B112 pin assignment open CPU (top view) All digital or analog functions described in this data sheet may be freely assigned to any GPIO pin. Analog functions are limited to analog capable pins. ☞ GPIO pins 25-31 and 36-37 are connected to pins located close to the radio part of the RF chip. It is recommended to avoid using these pins for high speed digital interfaces or sinking/sourcing large currents through them. Doing so may affect RF performance. ⚠ Do not apply an NFC field to the NFC pins when they are configured as GPIOs as it can cause permanent damage to the module. When driving different logic levels on these pins in GPIO mode, a small current leakage will occur. Ensure that they are set to the same logic level before entering into any power saving modes. See section 4.2.7 for more information.
