Security MCU offers high RF integration
Texas Instruments (Dallas, TX) introduced the RF430F5978 microcontroller (MCU) and accompanying evaluation module (EVM). Building on Tithe company’s CC430 product family, the RF430F5978 MCU is a highly integrated RF solution with desirable read zone and battery performance for ultra-low power applications. The MCU includes a 3D low-frequency (LF) wake-up and transponder interface, an integrated 1GHz RF transceiver and programmable MSP430 core. The LF transponder can even function without a battery supply. The 128-bit AES security encryption/decryption coprocessor adds advanced security for data protection. With its wake-up and localization RF connectivity, this highly integrated system-in-a-package solution is positioned to very small, compact designs with smaller batteries. The RF430F5978 MCUs:
- Reduce power consumption by allowing the shutdown of the RF radio and quick start-up of the LF wake-up function, thus extending battery life and the ability to shut down the radio and start up on the LF trigger.
- Tracks position and distance (within 5 cm) with the 3D LF transponder using RSSI (return signal strength indicator) within a 4 meter radius of a reader’s LF trigger.
- Protects sensitive data and prevents signal interference with the AES security coprocessor that allows data encryption for product authentication and secure access control.
