Features

• 802.15.4 Standard compliant transceiver supports 250 kbps O-QPSK data in 5.0 MHz channels and

full spread-spectrum encode/decode

• Operates on one of 16 selectable channels in the 2.4 GHz band

• Receive sensitivity of <-91 dBm (typical) at 1.0% packet error rate

• Recommended power supply range: 2.0 to 3.4 V

• 0 dBm nominal output power, programmable from -27 dBm to 4 dBm typical

• Buffered transmit and receive data packets for simplified use with low cost MCUs

• Three power down modes for increased battery life:

— < 1.0 µA Off current

— 2.3 µA Typical Hibernate current

— 35 µA Typical Doze current (no CLKO)

• Two internal timer comparators available to supplement MCU resources

• Programmable frequency clock output (CLKO) for use by MCU

• Onboard trim capability for 16 MHz crystal reference oscillator eliminates the need for external

variable capacitors and allows for automated production frequency calibration.

• Seven general purpose input/output (GPIO) signals

• Operating temperature range: -40 °C to +85 °C

• Small form factor QFN-32 Package
