MICRF002BM-0

RF Receivers Overview

The MICRF002BM-0 is a single-chip ASK/OOK RF receiver IC from Micrel Inc., operating within the 300MHz to 440MHz frequency range. It features a 16-pin SOP package with dimensions of 10mm length, 3.99mm width, and 1.64mm height. The device supports data rates up to 10kbps in fixed mode. Electrical specifications include a maximum operating supply voltage of 5.5V and a minimum of 4.75V. Current consumption is 2.2mA at 315MHz during full operation, 0.9µA in shutdown, and 220µA in polled operation with a 10:1 duty cycle. The operational temperature range spans from -40°C to +85°C.

RF Receivers Feature Summary

• Monolithic 'antenna-in to data-out' design eliminating manual tuning
• Automatic internal RF and IF tuning for reduced production costs
• Wake-up output flag capability for decoder and microprocessor enablement
• Very low RF re-radiation characteristics at the antenna port

RF Receivers Applications

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

RF Receivers Procurement Notes

Verify that the specific suffix '-0' aligns with the required tape and reel or tube packaging configuration as defined by Micrel's ordering information. Confirm that the 16-pin SOP package variant matches the PCB footprint requirements. Ensure the selected component meets the specified industrial temperature range if deployed in automotive or outdoor environments. Cross-reference the manufacturer part number against current datasheets to confirm pinout compatibility and feature set integrity before procurement.

RF Receivers Selection Notes

Select this component when a fully integrated ASK/OOK receiver solution is required without external tuning components. Consider the MICRF002YM for identical electrical performance in an alternative package format. Evaluate the MICRF022 only if an 8-pin package with a reduced feature set suffices for the application. Ensure the system design accommodates the 16-pin SOP footprint and provides adequate thermal management for the specified operating temperature range.

RF Receivers Part Context

The MICRF002BM-0 belongs to the QwikRadio family of low-power UHF receivers designed for simple, cost-effective wireless communication links. It represents a complete monolithic solution where all RF and IF functions are handled internally. This integration distinguishes it from discrete receiver designs, offering a compact alternative for manufacturers seeking to minimize bill-of-materials complexity while maintaining reliable signal reception in the sub-GHz ISM bands.

RF Receivers Replacement Considerations

The MICRF002YM serves as a direct functional equivalent with potential package differences. The MICRF022 offers similar core functionality but utilizes an 8-pin package with a reduced feature set. Verify pinout compatibility and feature availability when substituting these variants. No other direct substitutes are confirmed in public documentation.
