– Power Supply

• GPIO0

– internal module, launch control foot

• GPI01

– internal access module to accept control foot

• GPIO2

– directly connected to the chip GIIO2 pin

• VCC

– positive supply 3.3V

• SDO 0-VDD V

– digital output provides a serial readback function of the internal control register

• SDI serial data input

– 0-VDD V digital input, this pin for 4-wire serial data clock function

•  SCLK serial clock input

• NSEL serial interface

– select input pin,0-VDDV digital input

– This pin to 4-wire serial data bus select / enable function

– this signal is also used, said the burst read / write mode.

• NIRQ

• SDN Close the input pin

• GND 

• ANT
