<p>The Microchip ATA663254 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 5V/85mA. The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful slave nodes in LIN bus systems. Microchip ATA663254 is designed to handle the low-speed data communication in vehicles (for example, in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20Kbaud. The bus output is designed to withstand high voltage. 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<V_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 SO8 and DFN8 package with wettable flanks and pin assignment according to OEM hardware requirements for LIN-, CAN-, and Flexray- interfaces, rev. 1.3.</p><p>Please see our MikroElektronika click Board! <a href="https://www.mikroe.com/ata663254-click" rel="noopener noreferrer" target="_blank">https://www.mikroe.com/ata663254-click</a></p>
