GENERAL DESCRIPTION
The MSM6636B is a transmission controller for automotive LAN based on data communication
protocol SAE-J1850. This device can realize a data bus topology bus LAN system with a PWM
bit encoding method (41.6 kbps). In addition to a protocol control circuit, MSM6636B has an
enclosed quartz oscillation circuit, host CPU interface (parallel interface), a transmit/receive
buffer, and a bus receiver circuit that decreases the burden on the host CPU.
FEATURES
Based on SAE-J1850 CLASS B DATA COMMUNICATION NETWORK INTERFACE (issued
August 12, 1991)
Non-destructive collision and priority control using CSMA/CD
Internal transmit buffer (1 frame) and receive buffer (2 frames)
Modulating/demodulating: PWM (Pulse Width Modulation)
Transmission speed: 41.6 kbps
Multi-address setting with physical addressing: 1 type / functional addressing: 15 types
Address filter function by multi-addressing (broadcasting possible)
Automatic retransmission function by arbitration loss and non ACK
Three types of in-frame response support:
q
Single-byte response from a single node
w
Multi-byte response from a single node (with CRC code)
e
Single-byte response from multiple nodes (ID response as ACK)
Error detection by cyclic redundancy check (CRC)
Various communication error detections
Dual-wire bus abnormality detection by internal bus receiver and fault tolerance function
Host CPU interface is accessed in parallel
Sleep function
Low current consumption mode by oscillation stop (IDS Max < 50
μ
A)
SLEEP / WAKE UP control from host CPU, WAKE UP via LAN bus
Package:
24-pin plastic SOP (SOP24-P-430-1.27-K)(Product name : MSM6636BGS-K)
