  • Receive current is 18.5mA, maximum emission current of 80mA (200us).
  • Digital received signal strength indication (RSSI)
  • Timed wake-up function, wireless wake-up function (WUT)
  • The antenna automatically match and the two-way switch control
  • Configurable packet structure
  • The front synchronization signal detector
  • 64 bytes of data transceiver register (FIFO)
  • Chip integrated low-battery detection
  • The on-chip temperature sensor and 8-bit analog-to-digital converters
  • Operating temperature range: -40 to +80 ° C (temperature characteristics and product consistency is much better!)
  • The integrated regulator
  • Frequency hopping function

Pin out:

1. GND 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
