ATA6612C

8K/16K Flash Microcontroller with LIN Transceiver, 5V Regulator and Watchdog

Atmel Corporation 

3. LIN System-basis-chip Block

3.1 Features

● Master and slave operation possible

● Supply voltage up to 40V

● Operating voltage VS = 5V to 27V

● Typically 10µA supply current during sleep mode

● Typically 57µA supply current in silent mode

● Linear low-drop voltage regulator, 85mA current capability:

● Normal, fail-safe, and silent mode

● VCC = 5.0V ±2%

● In sleep mode VCC is switched off

● VCC - undervoltage detection (4ms reset time) and watchdog reset logical combined at open drain output NRES

● Negative trigger input for watchdog

● Boosting the voltage regulator possible with an external NPN transistor

● LIN physical layer according to LIN 2.0, 2.1 specification and SAEJ2602-2

● Wake-up capability via LIN-bus, wake pin, or Kl_15 pin

● INH output to control an external voltage regulator or to switch off the master pull Up resistor

● TXD time-out timer

● Bus pin is over temperature and short circuit protected versus GND and battery

● Adjustable watchdog time via external resistor

● Advanced EMC and ESD performance

● Fulfills the OEM “hardware requirements for LIN in automotive applications Rev.1.0”

● Interference and damage protection according ISO7637
