AN87C196LB

Product Summary

The AN87C196LB is a high-performance 16-bit microcontroller with integrated support for the J1850 communication protocol. The AN87C196LB is composed of a high-speed core with the following peripherals: an asynchronous/synchronous serial I/O port (8096 compatible) with a dedicated 16-bit baud-rate generator;an additional synchronous serial I/O port with full duplex master/slave transceivers; a six-channel A/D converter with sample and hold; a flexible timer/counter structure with prescaler, cascading, and quadrature capabilities;six modularized, multiplexed high-speed I/O for capture and compare (called event processor array) with 200 ns resolution and double buffered inputs; and a sophisticated prioritized interrupt structure with programmable peripheral transaction server (PTS).
