MICRF002BN

RF Receivers Overview

The MICRF002BN is a single-chip ASK/OOK RF receiver IC from Micrel Inc., operating within the 300MHz to 440MHz frequency range. It supports data rates up to 10kbps in fixed mode and features a sensitivity of -97dBm. The device operates on a supply voltage between 4.75V and 5.5V, with current consumption of 2.2mA during full operation at 315MHz, 220µA in polled operation, and 0.9µA in shutdown. It is housed in a 16-pin SOIC package.

RF Receivers Feature Summary

• Monolithic 'antenna-in to data-out' design with automatic RF and IF tuning
• Integrated wake-up output flag for enabling decoders and microprocessors
• Low power consumption with dedicated shutdown and polled modes
• Compact surface-mount compatible microcontroller interface

RF Receivers Applications

• Automotive remote keyless entry (RKE)
• Remote controls
• Remote fan and light control
• Garage door and gate openers

RF Receivers Procurement Notes

Verify the specific suffix BN against the manufacturer's official ordering guide to confirm pinout compatibility and package type. Ensure the procurement source provides valid RoHS compliance documentation as indicated in available records. Cross-reference the part number with the latest datasheet revision to confirm operational parameters match system requirements before finalizing purchase orders.

RF Receivers Selection Notes

Select this component for applications requiring low-cost, high-reliability ASK/OOK reception without manual tuning. The integrated nature reduces external part count compared to discrete solutions. Consider the 16-pin packaging constraints and the specific 300-440MHz band requirements. Evaluate power consumption profiles against battery life expectations for portable remote control designs.

RF Receivers Part Context

The MICRF002 series represents Micrel's QwikRadio line of low-power UHF receivers. The MICRF002 variant utilizes a 16-pin package with a full feature set, while the MICRF022 offers an 8-pin alternative with reduced functionality. This family targets cost-sensitive wireless control applications requiring robust performance and minimal external components.
