Product Brief
TLE983x System-on-Chip
Smart LIN-based Relay Driver IC &
Switch Panel Interface with integrated 8-bit MCU
The TLE983x 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 external
components is essential.
