Pin Assignment:

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. for SDO 0-VDD V digital output provides a serial readback function of the internal control register
7. for 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. for SDN Close the input pin. Input 0-VDDV digital. for SDN = 0 in shutdown mode, so mode
12. GND access power ground
13. ANT 50 ohm coaxial antenna
