Low Power Bluetooth 4.0 Module 3.0 Design References 3.1 Layout Design Guidelines Precaution: PCB layout is extremely important to minimize parasitical capacitance and line inductance. The following layout guidelines are recommended to achieve optimum performance. 1. Place ceramic bypass capacitors near the input/output pins. 2. All feedback signals must go through the regulator capacitors first. 3. Place the crystal and its components close to the oscillator side and near the oscillator pins. 4. Ensure that the ground plane under the module, oscillator and its components are in good quality. 5. Avoid long connections to the crystal and also to the load capacitor which may create a large loop on the PCB. 6. Do not route any digital-signal lines under the module, antenna keep-out region and crystal area. 7. Keep other digital signal lines, especially clock lines and frequently switching signal lines, as far away from the module as possible.

Low Power Bluetooth 4.0 Module 4.0 Power States & Sequence 4.1 Operation Mode State Power Down Sleep Standby TX RX Functional Description All power supplies are off except I/O for pin wake-up. All clocks are gated. System can be woken up by configured external pin. When it happens, PAR2801 resets from boot-up state. Active clocks (16MHz or 32MHz) are off, and the sleep clock remain working. Certain engines’ power are off. Two types of sleep modes are provided in PAJ2801. When CPU uses 16MHz crystal clock together with Bluetooth, it follows Bluetooth sleep mode aligning to connection interval. When CPU uses internal 32MHz RC clock, it can set CPU sleep mode independently and woken up by timer or Bluetooth interrupts. This is the default state after power-up. All clocks are working but the RF is inactive. This mode is entered when Bluetooth link-layer determines to send transmission packets. This mode is entered when Bluetooth link-layer determines to receive an incoming packet. Version 0.34 |29 Jul 2016 PixArt Imaging Inc. http://www.pixart.com All rights reserved.

Low Power Bluetooth 4.0 Module 5.0 System Description 5.1 ARM Cortes M0 The ARM® Cortex®-M0 processor is the smallest ARM processor available. It provides low power consumption and minimal code of the processor to enable developers to achieve 32-bit performance. With its friendly architecture, users can develop applications easily and fast. PAR2801QN-GH supports dynamic clock technology for various applications ranging from 8MHz to 32MHz. The CPU clock can be configured to use internal 32MHz RC clock or 16MHz crystal clock. When using RC clock, MCU can run independently with Bluetooth link-layer and switch on and off at users’ discretion. When using 16MHz crystal clock, it should follow the working period of Bluetooth. However, the Bluetooth working period can be determined by MCU. SWD (Serial-Wire Debug) is supported for powerful debug and trace features with two connection pins. PAR2801QN-GH has 24kB ROM for boot-up and BLE protocol stack, 128kB flash for profile/application, 48kB internal program SRAM, and 32kB data SRAM. 5.2 Bluetooth Low Energy Core The Bluetooth Low Energy Core is SIG Qualified. It is fully compliant with Bluetooth Smart v4.0 slave-role controller and provide qualified feature as below: 1. Bluetooth low energy stack All layers up to GATT including (PHY, LL, HCI, L2CAP, GAP, SM, ATT/GATT) 2. Slave-Role Link layer Slave-required PDU types Encryption/Decryption 3. L2CAP Slave connection update Attribute channel Security channel 4. GAP/ATT/GATT Mandatory protocols 5. Security Management Key generation and passing Automatic security engine 6. DTM DTM for RF qualification 7. Profile configuration Initialization Flexibility and testability Version 0.34 |29 Jul 2016 PixArt Imaging Inc. http://www.pixart.com All rights reserved.

With built-in on-chip balun, PAR2801QN-GH does not need external balun circuit to minimize BOM. The integrated high efficiency PA can transmit up to +4dBm RF power for class 2 operation, while the integrated low-IF receiver can provide excellent sensitivity up to -93dBm and outstanding interference rejection capability. 5.4 General Purpose ADC The PAR2801QN-GH integrates a low power 10-bit general purpose Analog-to-Digital Converter (GPADC) with 32kHz sampling rate. For each one shot measurement, it takes 150us for data acquisition. It can operate as a 4-channel ADC by switching the GPADC input. Two channels for internal Battery Voltage detection (VBAT3V, VBAT1V), while the other two are configured to monitor GPIO0 or GPIO1. For better accuracy, internal reference voltage calibration is preferred. Sensing applications as battery monitoring, temperature resister, analog signal sampling could be applied with this GPADC. 5.5 Power Management The PAR2801QN-GH integrates an power management unit for handheld or wearable devices with DC/DC(Buck or Boost) converter. No external Schottky diode is needed for minimal layout area. The DC/DC converter transforms battery voltage to a lower/higher internal voltage with minimal power loss. The DC/DC converter could provide excellent power efficiency with adaptive loading current setting. The DC/DC converter can be bypassed when the supply voltage drops to the lower limit of the voltage range, external DC/DC converter is also supported. It can provide power solution for one-cell LithiumIon, one-cell or multi-cell alkaline battery applications where the output voltage is adjustable. 5.5.1 Buck Converter Higher performance DC/DC Buck converter would bring up better battery life time. To ensure longest battery life, Buck converter has an optional bypass mode under light load current. The reduction in supply voltage level from a high voltage to a low voltage reduces the peak power drain from the battery. 5.5.2 GPIO PAJ2801UA-40 module offer 28 GPIOs and 2 output only ports (ICE_CLK, ICE_DATA). ICE_CLK and ICE_DATA pins should be make sure that keep Low during PAR2801 booting procedure. ICE_CLK and ICE_DATA could be configured as output pin after system boot up. 5.5.3 Timer PAR2801QN-GH provide 4 timers with 32-bit width. Timer0~Timer4 are running with 32.768kHz clock from 32.768kHz XTAL or LPO. Timer interrupt can wakeup CPU from sleep or power down mode. Timer3 is reserved for Rom Code. 5.5.4 Watch Dog Timer (WDT) PAR2801QN-GH offer one 16-bit countdown watchdog timer for supervisor purpose. It also runs at 32.768kHz clock for maximum 2sec supervisor time to execute system reset due to a hardware fault or program error. 5.5.5 PWM PAR2801QN-GH integrates three adjustable PWM generators, could be mux out at three different GPIO. The minimum positive or negative width of PWM is 1/32ms and flexible setting range from 1 to 255 steps. 5.5.6 LED Controller PAR2801QN-GH integrate LED controller which provide general On-OFF mode and breathe mode. The minimum LED on width is 1/32s with max 255 steps. LED ON-OFF repetition could be configured as continuous or 1~127 times. Register table has setting description details.

Low Power Bluetooth 4.0 Module 6.0 Interfaces 6.1 UART The PAR2801QN-GH has two sets of UART interface (UART0, UART1) for serial asynchronous communication between devices.UART-0 has CTS/RTS hard flow control for option. 8-n-1 is standard data frame configuration as eight (8) data bits, no (N) PAJity bit, and one (1) stop bit shown figure below. 6.2 I2C The PAR2801QN-GH has two sets of I2C interface (I2C_0, I2C_1) for 2-wire bi-directional communication between devices. The I2C supports wide range of data rate from 31.25kHz to 1000kHz in register controls. Multiple Read modes are supported as current read, random read, and sequential read. Write mode also support byte write and page write. 6.3 SPI The PAR2801QN-GH provides two configurations of SPI interfaces. One is four wire SPI, as CSN (chip select), SCLK (clock), SDI (MOSI data) and SDO (MISO data)and the other is two or three wire SPI interface as CSN (chip select) – optional, SCLK (clock), SDIO (bi-directional Data). These two configurations are for master operation only, slave mode is not supported. 6.3.1 Packet Formats The transmission protocol consists of the two operation modes: Write Operation. Read Operation. Both of the two operation modes consist of two bytes. The first byte contains the address (seven bits) and has bit-7 as its MSB to indicate data direction. The second byte contains the data. Version 0.34 |29 Jul 2016 PixArt Imaging Inc. http://www.pixart.com All rights reserved.
