Microchip Technology ATA663454
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. The bus output is designed to withstand high voltage.| Part No. | ATA663454 |
