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)
