CYRF89435-40LTXC

Product Overview

CYRF89435-40LTXC is a proprietary ISM RF transceiver IC or wireless MCU from Infineon Technologies. It is used in compact control, telemetry or remote-interface products requiring a matched RF solution. It is commonly selected for remote controls, sensors, industrial telemetry, security devices and legacy wireless products.

For design-in, continuation sourcing or repair work, engineers should review RF matching, antenna layout, interface timing, supply filtering and firmware compatibility. The selected orderable code should also be checked for package footprint, firmware or stack support, RF band, regulatory requirements and lifecycle status before approval.
