Engineering Brief

The RF430F5978 is a dual-frequency wireless MCU combining a 134.2 kHz ISO 11784/11785 FDX-B compliant RFID transponder with a Sub-1 GHz radio transceiver and MSP430 core. It enables battery-powered tracking devices to be read by standard livestock RFID readers while also transmitting extended data over long-range Sub-1 GHz wireless links. The integrated hardware AES-128 encryption and low-power modes make it ideal for secure, long-life livestock tags and remote asset monitoring applications in agricultural and industrial environments.
