Interfaces Configuration
Power Supply
Regulated power for the SKB360I is required. The input voltage Vcc should be
1.8V to 3.6V range, current is no less than 50mA. Suitable decoupling must be
provided by external decoupling circuitry (10uF and 1uF). It can reduce the Noise
from power supply and increase power stability.
Flash program I/Os
The module has two programmer pins, respectively SWCLK pin and SWDIO
pin. The two pin Serial Wire Debug (SWD) interface provided as a part of the De
bug Access Port (DAP) offers a flexible and powerful mechanism for non-intrusiv
e debugging of program code. Breakpoints and single stepping are part of this
support.
SWDIO can also be use as system reset pin,the system reset pin is avtive low.
GPIO
The general purpose I/O is organized as one port with up to 20 I/Os enabling
access and control of up to 20 pins through one port. Each GPIO can be access
ed individually with the following user configurable features:

SKB360 -DA-001,A/2
•Input/output direction
•Output drive strength
•Internal pull-up and pull-down resistors
•Wake-up from high or low level triggers on all pins
•Trigger interrupt on all pins
•All pins can be used by the PPI task/event system; the maximum number of pin
s that can be interfaced through the PPI at the same time is limited by the numb
er of GPIOTE channels
•All pins can be individually configured to carry serial interface or quadrature de
modulator signals
•All pins can be configured as PWM signal.
There are 4 ADC/LPCOMP input in the 20 I/Os.

Serial Peripheral Interface(SPI/SPIS)
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 SPI peripheral support SPI mode
0,1,2,and 3.The module have 3 SPI ports and they properties like following
table.

Two-wire Interface(TWI)
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 and 400 kbps. The module have
2 TWI ports and they properties like following table.
Instance Master/Slave
TWI0 Master
TWI1 Master
Universal Asynchronous Receiver/Transmitter (UART)
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.
Notify: The GPIOs used for each SPI/TWI/UART interface line can be chosen
from any GPIO on the device and are independently configurable.

Note ：The final soldering temperature chosen at the factory depends on
additional external factors like choice of soldering paste，size，thickness and
properties of the baseboard ，etc. Exceeding the maximum soldering
temperature in the recommended soldering profile may permanently damage the
module.
