The Atmel® ATA663431/54 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 with 3.3V/85mA
(ATA663431) or 5V/85mA (ATA663454). Additional the device includes a Watchdog, a high-side switch and 2 high-voltage wake inputs – one positive edge sensitive, one negative edge sensitive. This combination makes it possible to develop simple but powerful slave nodes in
LIN bus systems. Improved slope control at the LIN driver ensures secure data
communication up to 20Kbaud. Sleep mode and silent mode guarantee minimized
current consumption even in the case of a floating or a shorted LIN bus. The
voltage regulator is a fully integrated low-drop regulator working down to a
supply voltage of 2.3V with best-in-class current consumption in linear mode
(2V…VS...5V) with less than 170µA. This enables storing data within the MCU
during system shutdown even in case of an unexpected power supply
interruption. The device is available in DFN16 package with wettable
flanks to enable optical soldering inspection. The footprint is compatible with
the ATA663231/54 LIN system basis chip which enables customers to produce
modules with/without watchdog by assembling the LIN SBC with watchdog
(ATA663431/54) or the ATA663231/54 without watchdog.
