5. Interfaces
5.1 Power Supply
Regulated power for the SKB369 is required. The input voltage Vcc range should be 1.7V to 3.6V.
Suitable decoupling must be provided by external decoupling circuitry (10uF and 0.1uF). It can reduce
the noise from power supply and increase power stability.
5.2 System Function Interfaces
5.2.1 GPIOs
The general purpose I/O is organized as one port with up to 19 I/Os enabling access and control of up
to 19 pins through one port. Each GPIO can be accessed individually with the following user
configurable features:
1、Input/output direction
2、Output drive strength
3、Internal pull-up and pull-down resistors
4、Wake-up from high or low level triggers on all pins
5、Trigger interrupt on all pins
6、All pins can be used by the PPI task/event system; the maximum number of pins that
can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels
7、All pins can be individually configured to carry serial interface or quadrature demodulator signals
8、All pins can be configured as PWM signal.
9、There are 6 ADC/LPCOMP input in the 19 I/Os.
5.2.2 Two-wire Interface (I2C Compatible)
The two-wire interface can communicate with a bi-directional wired-AND bus with two lines (SCL,
SDA). The protocol makes it possible to interconnect up to 127 individually addressable devices. The
interface is capable of clock stretching, supporting data rates of 100 kbps ,250kbps and 400 kbps. The
module has 2 TWI ports and they properties like following table.

Note：I2C:Inter－Integrated Circuit
5.2.3 Flash Program I/Os
The module has two programmer pins, respectively SWDCLK pin and SWDIO pin. The two pin Serial
Wire Debug (SWD) interface provided as a part of the Debug Access Port (DAP) offers a flexible and
powerful mechanism for non-intrusive debugging of program code. Breakpoints and single stepping
are part of this support.
5.2.4 Serial Peripheral Interface
The SPI interfaces enable full duplex synchronous communication between devices. They support a
three-wire (SCK, MISO, MOSI) bi-directional bus with fast data transfers. The SPI Master can
communicate with multiple slaves using individual chip select signals for each of the slave devices
attached to a bus. Control of chip select signals is left to the application through use of GPIO signals.
SPI Master has double buffered I/O data. The SPI Slave includes EasyDMA for data transfer directly to
and from RAM allowing Slave data transfers to occur while the CPU is IDLE. The GPIOs are used for
each SPI interface line can be chosen from any GPIOs on the device and configed independently. This
enables great flexibility in device pinout and efficient use of printed circuit board space and signal
routing.
The SPI peripheral support SPI mode 0,1,2,and 3.The module have 3 SPI ports and theirs they
properties are as below:

5.2.5 UARTs
The Universal Asynchronous Receiver/Transmitter offers fast, full-duplex, asynchronous serial
communication with built-in flow control (CTS, RTS), support in hardware up to 1 Mbps baud. Parity
checking is supported.
Support the following baudrate in bps unit:
1200/2400/4800/9600/14400/19200/28800/38400/57600/76800/115200.
Note: The GPIOs are used for each SPI/TWI/UART interface line can be chosen from any GPIOs on the device and
configed independently.
5.2.6 Analog to Digital Converter (ADC)
The 12 bit incremental Analog to Digital Converter (ADC) enables sampling of up to 8 external signals
through a front-end multiplexer. The ADC has configurable input and reference prescaling, and
sample resolution (8,10, and 12 bit).
Note: The ADC module uses the same analog inputs as the LPCOMP module. Only one of the modules can be
enabled at the same time.

5.2.7 Low Power Comparator (LPCOMP)
In System ON, the block can generate separate events on rising and falling edges of a signal, or
sample the current state of the pin as being above or below the threshold. The block can be
configured to use any of the analog inputs on the device. Additionally, the low power comparator can
SKB369-DA-001,A/1
Bluetooth Module
Module SKB369

be used as an analog wakeup source from System OFF or System ON. The comparator threshold can
be programmed to a range of fractions of the supply voltage.
5.2.8 Reset
The reset pin of the SKB369 module is in the internal pull-high state , when the reset pin of the
module is input to a low level , the module will be automatically reset .After the reset pin is used , the
parameters of the current setting will not be ANT .
5.2.9 NFC
The NFC peripheral (referred to as the 'NFC peripheral' from now on) supports communication signal
interface type A and 106 kbps bit rate from the NFC Forum.
With appropriate software, the NFC peripheral can be used to emulate the listening device NFC-A as
specified by the NFC Forum.
Listed here are the main features for the NFC peripheral:
• NFC-A listen mode operation
• 13.56 MHz input frequency
• Bit rate 106 kbps
• Wake-on-field low power field detection (SENSE) mode
• Frame assemble and disassemble for the NFC-A frames specified by the NFC Forum
• Programmable frame timing controller
