Device Overview

Summary

The MICRF230 is a 400MHz to 450MHz super-heterodyne, image-reject, RF receiver with automatic gain control, ASK/OOK demodulator, analog RSSI output, and integrated squelch features.  It only requires a crystal and a minimum number of external components to implement.  The MICRF230 is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications.

The MICRF230 achieves -112dBm sensitivity at a bit rate of 1kbps with 1% BER. Four demodulator filter bandwidths are selectable using SEL0 and SEL1 from 1625Hz to 13kHz at 433.92MHz, allowing the device to support bit rates up to 20kbps.  The device operates from a supply voltage of 3.5V to 5.5V and typically consumes 6.0mA at 433.92MHz.  The MICRF230 has a shutdown mode that reduces current to 0.5µA.  The squelch feature decreases the activity on the data output pin until valid bits are detected while maintaining overall receiver sensitivity.
