The 87C196Kx devices represents the 4th generation of MCS 96 microcontroller products implemented on
Intel’s advanced 1 micron process technology These products are based on the 80C196KB device with
enhancements ideal for automotive applications The instruction set is a true super set of the 80C196KB with a
few new instructions
The MCS 96 microcontroller family members are all high performance microcontrollers with a 16-bit CPU The
87C196KT is composed of the high speed (16 MHz) KX macrocore as well as the following peripherals Up to
32 Kbytes of Program EPROM up to 1 Kbytes of Register RAM (00-3FFH including SFRs) up to 512 bytes of
code RAM (16-bit addressing modes) with the ability to execute from this RAM space an eight channel-10 Bit
g3LSB analog to digital converter with programmable S H times with conversion times k20 ms at 16 MHz an
asynchronous synchronous serial I O port (8096 compatable) with a dedicated 16-bit baud rate generator an
additional synchronous serial I O port with full duplex master slave transceivers a flexible timer counter
structure with prescaler cascading and quadrature capabilities 10 modularized multiplexed high speed I O
for capture and compare (called Event Processor Array) with 250 ns resolution and double buffered inputs
and a sophisticated prioritized interrupt structure with programmable Peripheral Transaction Server (PTS) The
PTS has several channel modes including single burst block transfers from any memory location to any
memory location a PWM and PWM toggle mode to be used in conjunction with the EPA and an A D scan
mode
Additional SFR space is allocated for the EPA and can be ‘‘windowed’’ into the lower Register RAM area

PIN DESCRIPTIONS (Continued)
Symbol
Name and Function
P5 5 BHE WRH
Byte High Enable or Write High output as selected by the CCR BHEe0 selects the
bank of memory that is connected to the high byte of the data bus A0e0 selects
that bank of memory that is connected to the low byte Thus accesses to a 16-bit
wide memory can be to the low byte only (A0e0 BHEe1) to the high byte only
(A0e1 BHEe0) or both bytes (A0e0 BHEe0) If the WRH function is selected
the pin will go low if the bus cycle is writing to an odd memory location BHE WRH is
only valid during 16-bit external memory write cycles Also an LSIO pin when not
BHE WRH
P5 6 READY
Ready input to lengthen external memory cycles for interfacing with slow or
dynamic memory or for bus sharing If the pin is high CPU operation continues in a
normal manner If the pin is low prior to the falling edge of CLKOUT the memory
controller goes into a wait state mode until the next positive transition in CLKOUT
occurs with READY high When external memory is not used READY has no effect
The max number of wait states inserted into the bus cycle is controlled by the CCR
CCR1 Also an LSIO pin when READY is not selected
P5 4 SLPINT
Dual function I O pin As a bidirectional port pin or as a system function The system
function is a Slave Port Interrupt Output Pin
P6 2 T1CLK
Dual function I O pin Primary function is that of a bidirectional I O pin however it
may also be used as a TIMER1 Clock input The TIMER1 will increment or
decrement on both positive and negative edges of this pin
P6 3 T1DIR
Dual function I O pin Primary function is that of a bidirectional I O pin however it
may also be used as a TIMER1 Direction input The TIMER1 will increment when
this pin is high and decrements when this pin is low
PORT1 EPA0–7
P6 0–6 1 EPA8–9
Dual function I O port pins Primary function is that of bidirectional I O System
function is that of High Speed capture and compare EPA0 and EPA2 have yet
another function of T2CLK and T2DIR of the TIMER2 timer counter
PORT 0 ACH0–7
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 These pins are also used as inputs to
EPROM parts to select the Programming Mode
P6 3–6 7 SSIO
Dual function I O ports that have a system function as Synchronous Serial I O Two
pins are clocks and two pins are data providing full duplex capability
PORT 2
8-bit multi-functional port All of its pins are shared with other functions
PORT 3 and 4
8-bit bidirectional I O ports with open drain outputs These pins are shared with the
multiplexed address data bus which has strong internal pullups
