Isolated Network High-Speed Transceiver

MC33664

Roll over image to zoom in

Our MC33664 is a transceiver physical layer transformer driver designed to conveniently interface a microcontroller to a high speed isolated communication network. MCU SPI data bits are directly converted to pulse bit information and transferred to the bus network.

  • Follower response messages use the same structure to send pulse bit information to the MC33664 which is then converted to an SPI bit stream sent back to the MCU. This device is powered by SMARTMOS® technology.
  • The MC33664 is designed for automotive and industrial applications and is compliant with the MC3377x battery cell controller family and MPC5xxx MCU families.
