ATA663431 Datasheet Lin Sbc Including Lin Transceiver

Manufacturer: Microchip Technology

Overview: ATA663431/54 LIN SBC including LIN Transceiver, Voltage Regulator, Window Watchdog and High-Side.

General Description

The ATA663431/54 is a new generation of system basis chip (SBC) with a fully integrated LIN transceiver, designed in compliance with LIN specifications 2.0, 2.1, 2.2, 2.2A, ISO 17987-4 and SAEJ2602-2, with a low-drop voltage regulator (3.3V/5V/85 mA), a window watchdog and a high-side switch.

This combination makes it possible to develop simple, but powerful, nodes in LIN-bus systems.

ATA663431/54 is designed to handle low-speed data communication in vehicles (such as in
