Silicon Laboratories has introduced an MCU family for car body electronics - claimed to be the first to support CAN and LIN without an external crystal or resonator.

"It provides a true 5x5mm single-chip communication network solution," a company spokesman told EW.
According to the company, the internal oscillator provides an accuracy of +/-0.5% across the entire -40 to +125 deg C temperature and 1.8 to 5.25V supply range.

The C8051F50x family, as it is to be known, includes a 50Mips core, up to 64kbyte of flash, 4kbyte of RAM, and hardware controllers for CAN 2.0B (32 message buffer) and LIN 2.0.

Also on-die is a 12bit, 200ksample/s ADC with 32 channels, a voltage reference, a comparator and a temperature sensor.

"The comparator can be dynamically re-mapped to different I/O pins during run-time providing a simple solution for motor commutation," said the company.

Applications including window lifters, seat positioning and steering angle sensing are foreseen.
The family is available now in 32 and 48pin QFN and QFP packages.

The full C8051F500DK development kit is available, plus the lower cost ToolStick502DC for use with Silicon Lab's ToolStick base adapter.
