The 87C196LA is a high-performance 16-bit microcontroller. The 87C196LA 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 sophis-
ticated, prioritized interrupt structure with programmable peripheral transaction server (PTS). The clock
doubler circuitry and oscillator output signal enable a 4 MHz resonator to achieve the same internal clock
speed as a more costly 8 MHz resonator in previous applications. This same circuitry can drive other devices
where a separate resonator was required in the past. Another cost-savings feature is the fact that the I/O
ports are driven low at reset, avoiding the need for pull-up resistors.
