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 sophisticated, 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.
