The 8XC196KB 16-bit microcontroller comes with 8 Kbytes of on-chip mask programmable ROM or in ROM-
less versions. All devices are high performance members of the 8096 microcontroller family. The 8XC196KB is
pin-to-pin compatible and uses a true superset of the 8096 instructions. Intel’s CHMOS process provides a
high performance processor along with low power consumption. To further reduce power requirements, the
processor can be placed into Idle or Powerdown Mode.
Bit, byte, word and some 32-bit operations are available on the 8XC196KB. With a 16 MHz oscillator, a 16-bit
addition takes 0.495 ms, and the instruction times average 0.375 ms to 1.125 ms in typical applications.
Four high-speed capture inputs are provided to record times when events occur. 4
a
2 high-speed outputs are
available for pulse or waveform generation. The high-speed output can also generate four software timers or
start an A/D conversion. Events can be based on the 16-bit timer or a 16-bit up/down counter.
Also provided on-chip are an 8 channel, 10-bit A/D converter with Sample and Hold, a serial port with
synchronous/asynchronous modes and on-chip baud rate generator, a 16-bit watchdog timer, pulse width
modulated output with prescaler and an on-chip clock failure detect circuitry.
