Infineon TLE983x Intelligent Automotive Relay Driver Solution

The TLE983x from Infineon is a single chip solution that integrates a high performance 8-bit microcontroller derived from the established XC800 family with application specific power drivers, control and communication modules in an automotive qualified new Smart-Power Technology. The TLE983x family concept offers scalability in terms of Flash memory sizes ranging from 36kB to 64kB with pin-compatible devices. The TLE983x family was specifically designed to fit to a wide range of LIN-slave applications where a small package form factor and a minimum number of LIN-slave modules are required

. of external components is essential. TLE983x main features: • High performance P ) – 512 Byte 100 Time Programmable Memory ( 100TP ) – 256 Byte RAM – 3 kByte Port (GPIO) with wake-up capability • Multiplication/division unit (MDU) for arithmetic calculation • Software libraries to support floating point and MDU calculations • Five 16-Bit timers - Timer 0, Timer 1, Timer 2, Timer 21 and Timer 3 • Capture/compare unit for PWM signal generation (CCU6) and Hall Sensor measurement with Timer 12 and Timer 13 • Full duplex serial interface (UART) with LIN support • Synchronous serial channel (SSC) • On-chip debug support via 2-wire Device Access Port (DAP) • LIN Bootstrap loader (LIN BSL) • LIN transceiver compliant to LIN 1.3, LIN 2.0 and LIN 2.1 • 2 x Low Side Switches with clamping capability incl. PWM functionality, eg as relay driver • 1 or 2 x High Side Switches with cyclic sense option and PWM functionality, eg for LED powering of switches • High Voltage Monitor Input pins for wake-up and with cyclic sense and analog measurement option • Measurement unit with 10 channels, 8-Bit A/D Converter (ADC2) and data post processing
