AX-SFEU-1-01-TB05

RF Transceiver ICS Overview

The AX-SFEU-1-01-TB05 is an integrated RF System-on-Chip (SoC) combining a transceiver and microcontroller unit. It operates within the sub-1 GHz ISM band, specifically tuned for 868 MHz applications. The device supports GFSK modulation with a maximum data rate of 600 bps. Electrical specifications include a receive sensitivity of -126 dBm and a transmit power output of 14 dBm. Supply voltage ranges from 1.8 V to 3.6 V, with current consumption of 10 mA during reception and 19 mA to 49 mA during transmission. It features SPI and UART serial interfaces, ten GPIOs, and is housed in a 40-VFQFN package with exposed pad dimensions of 7x5 mm.

RF Transceiver ICS Procurement Notes

This component has reached End-of-Life status as per Product Change Notification issued in March 2018. Distribution channels indicate restricted supply or discontinuation. Verify availability through official obsolescence notices and confirm alternative sourcing strategies immediately. Do not rely on standard inventory levels for new production designs.

RF Transceiver ICS Selection Notes

Select this part only for legacy systems requiring specific Sigfox compatibility at 868 MHz. The integrated MCU reduces external component count but limits processing flexibility compared to separate SoCs. Ensure interface requirements match the available SPI and UART protocols. Consider thermal management due to the QFN package layout.

RF Transceiver ICS Part Context

Part of the AX-SFEU family designed for ultra-low power wireless applications. Manufactured by onsemi, it targets the industrial IoT sector. The series emphasizes minimal energy consumption for battery-operated devices. This specific model variant includes the necessary RF front-end and baseband processing for certified Sigfox network integration.

RF Transceiver ICS Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Due to EOL status, evaluate generic sub-1 GHz transceivers paired with external MCUs. Verify pinout and register compatibility if migrating to other vendors' ISM band solutions.
