Page 1 of 21

REV. 18

MAY 2017

Features

Microcontroller: MLX16x8 RISC CPU

 16 bit RISC-CPU

 Co-processor for fast multiplication and division

 In-circuit debug and emulation

Memories

 32 kByte Flash with ECC

 2 kByte RAM

 380 Byte EEPROM with separate RAM (also called NVRAM), with ECC, for customer purposes

Supported bus interface

 LIN-Interface with integrated LIN transceiver supporting LIN 2.x and SAE J2602, certified LIN protocol software

provided by Melexis

 In-Module-Programming (Flash and EE) via pin LIN using a special Melexis fast protocol

 PWM-Interface

 Full duplex SPI, Master/Slave, double-buffered, speed programmable

Voltage regulator

 Internal voltage regulator, direct powered from 12V battery supply

 Operating voltage VS = 5.5V to 18V, IC will work down to 3.9V

 Possibility to put an external bypass transistor for high temperature requirements

 Very low SLEEP MODE current < 30uA, Wake up by LIN traffic or local sources

Periphery

 4 programmable 16bit PWM modules for external transistor full bridge applications

 Timer unit 16 bit with 4 capture and 4 compare

 25 MHz +/-5% internal RC-oscillator with PLL, optional crystal resonator

 Load dump and brown out interrupt function

 Digital watchdog for software flow tracking

 System-Clock-independent fully integrated watchdog

 On-chip temperature sensor with +/-10K accuracy

 10 bit ADC with < 6 µs conversion time with multiple channels and different ADC references, DMA access to RAM

 8 multiple purpose I/Os

 2 integrated relay drivers with free wheel function

 2 inputs for relay contact or shunt current monitoring

 Over current detection, shunt current sense

 1 switch-able supply output for external Hall sensor connection

Additional features

 Direct access to pin LIN possible

 Temperature range -40°C up to 150°C ambient

 28V jump start and 45V load dump protected

 Monolithic solution: Single chip in single package realization

 Small QFN32 5x5
