ATA663255 - Microchip

ATA663255 LIN System Basis Chip Including LIN Transceiver

The ATA663232/55 system basis chip is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2, with a low drop voltage regulator (3.3V/5V/85 mA) and a high voltage wake-input. The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful nodes in LIN bus s.
