General Description
 Ready for Bluetooth 5 and high grade IoT security
  The SKB501 is an advanced, highly flexible single chip solution for today’s increasingly demanding ULP
wireless applications for connected devices on our person, connected living environments and the IoT at
large. It is designed ready for the major feature advancements of Bluetooth® 5 and takes advantage of
Bluetooth 5’s increased performance capabilities which include long range and high throughput modes.
Inherent industry-grade security is essential in today’s applications.


 Bluetooth 5 – Bluetooth low energy further and faster
 The nRF52840 is ready to take advantage of the considerable performance improvements for Bluetooth
low energy with the arrival of the Bluetooth 5 specification. Of greatest importance is the support for longer
range (up to x4 compared to Bluetooth 4.x) and doubling of on-air data-rate, up to 2Mbs from 1Mbs in
Bluetooth 4.x


Wide protocol support with addition of 802.15.4
 The 802.15.4 PHY and MAC layers are supported natively on the nRF52840. This allows nRF52840 to be
used in a wide range of home and industrial sensor network applications as it supports two of the most
popular wireless sensor standards in use today, Bluetooth low energy and 802.15.4 derivatives. This adds to
the already existing radio support for Bluetooth low energy.

Interfaces
Power Supply
Regulated power for the SKB501 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.

System Function Interfaces

GPIOs

The general purpose I/O is organized as one port with up to 20 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

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 20 I/Os.

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

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.

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:
