Pin definitions:

1 CND power supply. 2 GPIO0 internal module, launch control foot. 3 GPI01 internal access module to accept control foot. 4 GPIO2 directly connected to the chip GIIO2 pin. 5 VCC positive supply 3.3V. 6 SDO 0-VDD V digital output provides a serial readback function of the internal control register. 7 SDI serial data input. 0-VDD V digital input, this pin for 4-wire serial data clock function. 8 SCLK serial clock input. 0-VDDV last month set of inputs. This pin provides a 4-wire serial data clock function. 9 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. 10 NIRQ interrupt output pin. 11 SDN Close the input pin. Input 0-VDDV digital. SDN = 0 in shutdown mode, so mode. 12 GND access power ground. 13 ANT 50 ohm coaxial antenna.
