The 87C196KD 16-bit microcontroller is a high-performance member of the MCS 96 microcontroller family
The 87C196KD is an enhanced 8XC196KC device with 1000 bytes RAM 16 MHz operation and 32 Kbytes of
on-chip EPROM Intel’s CHMOS process provides a high-performance processor along with low power con-
sumption
Four high-speed capture inputs are provided to record times when events occur Six 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 timer or up down counter
