The 87C196KC 16-bit microcontroller is a high-performance member of the MCS 96 microcontroller family
The 87C196KC is an enhanced 8XC196KB device with 488 bytes RAM 16 MHz operation and 16 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

PIN DESCRIPTIONS (Continued)
Symbol
Name and Function
READY
Ready input to lengthen external memory cycles for interfacing to slow or dynamic memory
or for bus sharing When the external memory is not being used READY has no effect
HSI Inputs to High Speed Input Unit Four HSI pins are available HSI 0 HSI 1 HSI 2 and HSI 3
Two of them (HSI 2 and HSI 3) are shared with the HSO Unit
HSO
Outputs from High Speed Output Unit Six HSO pins are available HSO 0 HSO 1 HSO 2
HSI 3 HSO 4 and HSO 5 Two of them (HSO 4 and HSO 5) are shared with the HSI Unit
Port 0
8-bit high impedance input-only port These pins can be used as digital inputs and or as
analog inputs to the on-chip A D converter
Port 1
8-bit quasi-bidirectional I O port
Port 2
8-bit multi-functional port All of its pins are shared with other functions in the 87C196KC
Ports 3 and 4 8-bit bidirectional I O ports with open drain outputs These pins are shared with the
multiplexed address data bus
HOLD
Bus Hold input requesting control of the bus
HLDA
Bus Hold acknowledge output indicating release of the bus
BREQ
Bus Request output activated when the bus controller has a pending external memory
