security MCU EVMTexas 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.
