ATA8520D-GHQW

RF Transceiver ICS Overview

The ATA8520D-GHQW is a fully integrated single-chip RF transceiver and microcontroller unit designed for SIGFOX applications. Operating at 868MHz, it supports DBSPK and GFSK modulation with a maximum data rate of 600bps. The device features a transmit power of 14dBm and a receive sensitivity of -121.5dBm. It operates on supply voltages ranging from 1.9V to 3.6V or 2.4V to 5.5V. Receive current is 10.4mA, while transmit current ranges from 31.8mA to 32.7mA. Communication utilizes an SPI interface. The component is housed in a 32-VFQFN package with exposed pads and functions within a temperature range of -40°C to 85°C.

RF Transceiver ICS Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus stock rather than direct manufacturing orders. Confirm RoHS3 compliance and MSL level 3 status during sourcing. Cross-reference datasheet revisions to ensure firmware compatibility with target SIGFOX infrastructure requirements before procurement.

RF Transceiver ICS Selection Notes

Select this part when a combined MCU and RF transceiver is required for SIGFOX protocols. It eliminates external baseband processing needs. Verify voltage domain compatibility with host systems due to dual supply range options. Ensure thermal management suits the 32-VFQFN package constraints. Consider pinout differences if comparing against other variants in the ATA8520 family.

RF Transceiver ICS Part Context

The ATA8520D-GHQW belongs to the ATA8520 series, which targets low-power wide-area network applications. It integrates radio frequency front-end capabilities with digital control logic. The 'D' suffix typically denotes specific firmware or feature sets within the product line. It competes in the market for certified SIGFOX end-device components.

RF Transceiver ICS Replacement Considerations

Public confirmed substitutes include ATA8520D-GHPW and ATA8520E-GHQW. Verify package pinout alignment and firmware version compatibility when transitioning between these variants.
