• Manufacturer Part Number: 87C196KC
• Description: 16-BIT HIGH PERFORMANCE CHMOS MICROCONTROLLER
• Manufacturer: Intel Corporation

AUTOMOTIVE 87C196KC
87C196KC Enhanced Feature Set over the 87C196KB
1 The 87C196KC has twice the RAM and twice the EPROM of the 87C196KB Also a Vertical Register
2 Peripheral Transaction Server (PTS) The PTS is an alternative way to service an interrupt reducing latency
3 Two extra Pulse Width Modulated outputs The 87C196KC has added 2 PWM outputs that are functionally
4 Timer2 Internal Clocking Timer2 can now be clocked with an internal source every 1 or 8 state times
5 The A D can now perform an 8- as well as a 10-bit conversion 8-bit conversion allows for a faster
6 Additional On-chip Memory Security Two UPROM (Uneraseable Programmable Read Only Memory) bits
7 New Instructions The 87C196KC has 5 new instructions An exchange (XCHB XCHW) instruction swaps
2
Windowing Scheme allows the extra 256 bytes of RAM to be used as registers This greatly reduces the
context switching time
and overhead Each interrupt can be mapped to its PTS channel which acts like a DMA channel Each
interrupt can now do a single or block transfer without executing an Interrupt service routine Special PTS
modes exist for the A D converter HSI and HSO
compatible to the 87C196KB PWM
conversion time
can be programmed to disable the bus controller for external code and data fetches Once programmed a
UPROM bit cannot be erased By shutting off the bus controller for external fetches no one can try and
gain access to your code by executing from external memory
two memory locations an Interruptable Block Move Instruction (BMOVI) a Table Indirect Jump (TIJMP)
instruction and two instructions for enabling and disabling the PTS (EPTS DPTS)
