GENERAL DESCRIPTION
The MSM9225 is a microcontroller peripheral LSI which conforms to the CAN protocol for high-speed LANs in automobiles.

FEATURES
• Conforms to CAN protocol specification (Bosch Co., V.2.0 part b/Full CAN)
• Maximum 1 Mbps real-time communication control (programmable)
• Communication system:
    Transmission line is bi-directional, two-wire serial communications
    NRZ (Non-Return to Zero) system using bit stuff function
    Multi-master system
    Broadcast system
• Maximum 16 messages x 8 bytes of message buffer
    Number of messages can be extended by group message function (max: 2 groups)
• Priority control by identifier
    Normally 2032 types, 2032 x 218 types at extension
• Microcontroller interface
    Corresponding to both parallel and serial interface
        Parallel interface: separate address/data bus type (with address latch signal/no address latch signal) and multiplexed address/data bus type.
        Serial interface: Synchronous communication type
    Interrupt is used for three outputs: transmission/receive/error
• Error control:
    Bit error/stuff error/CRC error/form error/acknowledge error detection functions
    Retransmission / error status monitoring function when error occurs
• Communication control by transmission request function
• Sleep/Stop mode function
• Supply voltage: 5 V ±10%
• Operating temperature: -40 to +115˚C
• Package: 44-pin plastic QFP (QFP44-P-910-0.80-2K) (Product name: MSM9225GA-2K)
