RF Transceiver ICS Procurement Notes

Verify the suffix ZFR indicates tape and reel packaging when ordering. Confirm the component meets RoHS compliance requirements for your specific manufacturing process. Ensure the 64-pin QFN EP package dimensions align with your PCB footprint design. Check for any recent product change notices regarding marking or assembly specifications from Microchip Technology.

RF Transceiver ICS Selection Notes

Select this component for applications requiring combined MCU and RF capabilities in a compact form factor. The 128 KB Flash size accommodates complex protocol stacks like Zigbee. Consider the 1.8 V to 3.6 V supply range for battery-operated designs. Evaluate the 16 MHz throughput against processing requirements for real-time control tasks.

RF Transceiver ICS Part Context

This part belongs to the ATmega128RFA1 family of RF microcontrollers from Microchip Technology. It combines the AVR RISC core with an on-chip 2.4 GHz transceiver. The ZFR suffix specifically denotes the tape and reel packaging variant, distinguishing it from tray-packaged versions like the -ZU suffix.

RF Transceiver ICS Replacement Considerations

The ATMEGA128RFA1-ZU is a pin-compatible alternative with identical electrical characteristics but differs in packaging format. Verify that the receiving equipment supports tape and reel handling if switching from tray packages.
