ATA8520E-GHQW

RF Transceiver ICS Overview

The ATA8520E-GHQW is an RF transceiver integrated with a low-power 8-bit AVR microcontroller, designed for ISM band applications below 1GHz. It supports the SIGFOX protocol and operates at frequencies including 868MHz and 902MHz. The device features a transmitter output power of up to 14.5dBm and a receiver sensitivity of -121.5dBm. Maximum data rate is 600bps. Supply voltage ranges from 1.9V to 3.6V. Transmit current is approximately 31.8mA to 32.7mA, while receive current is 10.4mA. It utilizes SPI serial interface and is housed in a 32-VFQFN package with exposed pad.

RF Transceiver ICS Procurement Notes

This component is officially listed as inactive or obsolete by Microchip Technology. Verification of availability through authorized distributors is required, as stock may be limited or subject to last-time-buy status. Ensure compatibility with existing PCB footprints and firmware configurations before procurement planning. Cross-reference part numbers carefully due to potential suffix variations affecting packaging or temperature range.

RF Transceiver ICS Selection Notes

Select this component when designing for SIGFOX-compliant long-range communication requiring integrated MCU control. Verify that the application frequency aligns with regional ISM allocations such as 868MHz or 902MHz. Consider the 32-VFQFN package constraints for thermal management and PCB layout. Confirm supply chain viability given the product's inactive status and explore alternative sources if continuous production is required.

RF Transceiver ICS Part Context

The ATA8520E belongs to the Atmel ATA8520 series, which combines RF transceiver capabilities with an AVR microcontroller for simplified system design. This integration reduces component count and board space compared to discrete solutions. The E variant specifically denotes FCC-certified kits suitable for North American markets, distinguishing it from other regional variants within the same family.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the integrated MCU and specific SIGFOX certification, direct pin-to-pin replacements may require firmware adaptation. Consult Microchip Technology for current lifecycle updates or recommended alternatives.
