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
