Version
The 87C196KC is an 80C196KC with 16 Kbytes on-chip OTPROM. The 83C196KC is an 80C196KC with 16
Kbytes factory programmed ROM. In this document, the 80C196KC will refer to all products unless otherwise
stated.
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.
With the commercial (standard) temperature option, operational characteristics are guaranteed over the temperature range of 0
