Features
• Recommended power supply range: 2.0 to 3.4 V
• 16 Channels
• 0 dBm nominal, programmable from -27 dBm to 4 dBm typical maximum output power
• Buffered transmit and receive data packets for simplified use with low cost MCUs
• Supports 250 kbps O-QPSK data in 5.0 MHz channels and full spread-spectrum encode and decode
(compatible with IEEE Standard 802.15.4)
• Three power down modes for power conservation:
— < 1 µA Off current
— 1 µA Typical Hibernate current
— 35 µA Typical Doze current (no CLKO)
• RX sensitivity of -92 dBm (typical) at 1.0% packet error rate
• Four internal timer comparators available to reduce MCU resource requirements
• Programmable frequency clock output for use by MCU
• Onboard trim capability for 16 MHz crystal reference oscillator eliminates need for external
variable capacitors and allows for automated production frequency calibration.
• Seven general purpose input/output (GPIO) signals
