Product Summary

The MSM6636GS-KR1 is a transmission controller for automotive LAN based on data communication protocol SAE-J1850. The MSM6636GS-KR1 can realize a data bus topology bus LAN system with a PWM bit encoding method (41.6 K bps). In addition to a protocol control circuit, MSM6636GS-KR1 has an enclosed quartz oscillation circuit, host CPU interface (clock synchronous serial / UART), a transmit/ receive buffer, and a bus receiver circuit that decreases the burden on the host CPU.

Parametrics

MSM6636GS-KR1 absolute maximum ratings: (1)Power Supply Voltage DVDD, AVDD: -0.3~7.0 V; (2)Input Voltage VI AVDD = DVDD: -0.3~DVDD+0.3 V; (3)Output Voltage VO AVDD = DVDD: -0.3~DVDD+0.3 V; (4)Power Dissipation PD(DIP)*1 Ta = 25°C: 860 mW; (5)Power Dissipation PD(QFJ)*2 Ta = 25°C: 960 mW; (6)Power Dissipation PD(SOP)*3 Ta = 25°C: 830 mW; (7)Storage Temperature TSTG: -55~150 °C.

Features

MSM6636GS-KR1 features: (1) Based on SAE-J1850 CLASS B DATA COMMUNICATION NETWORK INTERFACE (issued August 12, 1991); (2) CSMA/CD (Carrier-sense multiple access with collision detection); (3) Internal transmit buffer (1 frame) and receive buffer (2 frames); (4) Bit encoding: PWM (Pulse Width Modulation); (5) Transmission Speed: 41.6K bps; (6) Multi-address setting with physical addressing: 1 type / functional addressing: 15 types; (7) Address filter function by multi-addressing (broadcasting possible); (8) Automatic retransmission function by arbitration loss and non ACK.
