The 8XC196KB is a 16-bit microcontroller available in three different memory varieties: ROMless (80C196KB),
8K ROM (83C196KB) and 8K OTP (One Time ProgrammableÐ87C196KB). The 8XC196KB is a high performance member of the MCSÉ 96 microcontroller family. The 8XC196KB has the same peripheral set as the
8096BH and has a true superset of the 8096BH instructions. Intel’s CHMOS process provides a high performance processor along with low power consumption. To further reduce power requirements, the processor can
be placed into Idle or Powerdown Mode.
Bit, byte, word and some 32-bit operations are available on the 80C196KB. With a 16 MHz oscillator a 16-bit
addition takes 0.50 ms, and the instruction times average 0.37 ms to 1.1 ms in typical applications.
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. Also provided on-chip are an
A/D converter, serial port, watchdog timer and a pulse-width-modulated output signal.
The 8XC196KB has a maximum guaranteed frequency of 12 MHz. The 8XC196KB16 has a maximum guaranteed frequency of 16 MHz. All references to the 80C196KB also refer to the 80C196KB16; 83C196KB, Rxxx;
87C196KB and 87C196KB16 unless otherwise noted. The ROM device does not have a speed indicator at the
end of the device name. Instead it has a ROM code number.
With the commercial (standard) temperature option, operational characteristics are guaranteed over the temperature range of 0§ C to a 70§ C. With the extended temperature range option, operational characteristics are
guaranteed over the temperature range of b 40§ C to a 85§ C.

PIN DESCRIPTIONS
Symbol
Name and Function
VCC
Main supply voltage (5V).
VSS
Digital circuit ground (0V). There are multiple VSS pins, all of them must be connected.
VREF
Reference voltage for the A/D converter (5V). VREF is also the supply voltage to the analog
portion of the A/D converter and the logic used to read Port 0. Must be connected for A/D
and Port 0 to function.
ANGND
Reference ground for the A/D converter. Must be held at nominally the same potential as
VSS. Connect VSS and ANGND at chip to avoid noise problems.
VPP
Programming voltage. Also timing pin for the return from power down circuit.
XTAL1
Input of the oscillator inverter and of the internal clock generator.
XTAL2
Output of the oscillator inverter.
CLKOUT
Output of the internal clock generator. The frequency of CLKOUT is (/2 the oscillator
frequency. It has a 50% duty cycle.
RESET
Reset input to and open-drain output from the chip. Input low for at least 4 state times to reset
the chip. The subsequent low-to-high transition re-synchronizes CLKOUT and commences a
10-state-time RESET sequence.
BUSWIDTH
Input for buswidth selection. If CCR bit 1 is a one, this pin selects the bus width for the bus
cycle in progress. If BUSWIDTH is a 1, a 16-bit bus cycle occurs. If BUSWIDTH is a 0 an 8-bit
cycle occurs. If CCR bit 1 is a 0, the bus is always an 8-bit bus.
NMI
A positive transition causes a vector through 203EH.
INST
Output high during an external memory read indicates the read is an instruction fetch and
output low indicates a data fetch. INST is valid throughout the bus cycle. INST is activated
only during external memory accesses.
EA
Input for memory select (External Access). EA equal to a TTL-high causes memory accesses
to locations 2000H through 3FFFH to be directed to on-chip ROM/OTPROM. EA equal to a
TTL-low causes accesses to these locations to be directed to off-chip memory.
ALE/ADV
Address Latch Enable or Address Valid output, as selected by CCR. Both pin options provide
a latch to demultiplex the address from the address/data bus. When the pin is ADV, it goes
inactive high at the end of the bus cycle. ALE/ADV is activated only during external memory
accesses.
RD
Read signal output to external memory. RD is activated only during external memory reads.
WR/WRL
Write and Write Low output to external memory, as selected by the CCR. WR will go low for
every external write, while WRL will go low only for external writes where an even byte is
being written. WR/WRL is activated only during external memory writes.
BHE/WRH
Bus High Enable or Write High output to external memory, as selected by the CCR. BHE will
go low for external writes to the high byte of the data bus. WRH will go low for external writes
where an odd byte is being addressed. BHE/WRH is activated only during external memory
writes.
READY
Ready input to lengthen external memory cycles. If the pin is low prior to the falling edge of
CLKOUT, the memory controller goes into a wait mode until the next positive transition in
CLKOUT occurs with READY high. When the external memory is not being used, READY has
no effect. Internal control of the number of wait states inserted into a bus cycle (held not
ready) is available in the CCR.
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,
HSO.3, HSO.4 and HSO.5. Two of them (HSO.4 and HSO.5) are shared with the HSI Unit.

PIN DESCRIPTIONS (Continued)
Symbol
Name and Function
Port 0
8-bit high impedance input-only port. Three 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. These pins are shared with HOLD, HLDA and BREQ.
Port 2
8-bit multi-functional port. All of its pins are shared with other functions in the 87C196KB.
Pins P2.6 and P2.7 are quasi-bidirectional.
Ports 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.
HOLD
Bus Hold input requesting control of the bus. Enabled by setting WSR.7.
HLDA
Bus Hold acknowledge output indicating release of the bus. Enabled by setting WSR.7.
BREQ
Bus Request output activated when the bus controller has a pending external memory
cycle. Enabled by setting WSR.7.
TxD
The TxD pin is used for serial port transmission in Modes 1, 2 and 3. In Mode 0 the pin is
used as the serial clock output.
RxD
Serial Port Receive pin used for serial port reception. In Mode 0 the pin functions as input or
output data.
EXTINT
A rising edge on the EXTINT pin will generate an external interrupt.
T2CLK
The T2CLK pin is the Timer2 clock input or the serial port baud rate generator input.
T2RST
A rising edge on the T2RST pin will reset Timer2.
PWM
The pulse width modulator output.
T2UP-DN
The T2UPDN pin controls the direction of Timer2 as an up or down counter.
T2CAPTURE
A rising edge on P2.7 will capture the value of Timer2 in the T2CAPTURE register.
PMODE
Programming Mode Select. Determines the EPROM programming algorithm that is
performed. PMODE is sampled after a chip reset and should be static while the part is
operating.
SID
Slave ID Number. Used to assign each slave a pin of Port 3 or 4 to use for passing
programming verification acknowledgement.
PALE
Programming ALE Input. Accepted by the 87C196KB when it is in Slave Programming
Mode. Used to indicate that Ports 3 and 4 contain a command/address.
PROG
Programming. Falling edge indicates valid data on PBUS and the beginning of
programming. Rising edge indicates end of programming.
PACT
Programming Active. Used in the Auto Programming Mode to indicate when programming
activity is complete.
PVAL
Program Valid. This signal indicates the success or failure of programming in the Auto
Programming Mode. A zero indicates successful programming.
PVER
Program Verification. Used in Slave Programming and Auto CLB Programming Modes.
Signal is low after rising edge of PROG if the programming was not successful.
AINC
Auto Increment. Active low signal indicates that the auto increment mode is enabled. Auto
Increment will allow reading or writing of sequential EPROM locations without address
transactions across the PBUS for each read or write.
Ports 3
and 4
(Programming
Mode)
Address/Command/Data Bus. Used to pass commands, addresses, and data to and from
slave mode 87C196KBs. Used by chips in Auto Programming Mode to pass command,
addresses and data to slaves. Also used in the Auto Programming Mode as a regular
system bus to access external memory. Should have pullups to VCC when used in slave
programming mode.

EXTERNAL CLOCK DRIVE WAVEFORMS
270909 – 10
An external oscillator may encounter as much as a 100 pF load at XTAL1 when it starts-up. This is due to
interaction between the amplifier and its feedback capacitance. Once the external signal meets the VIL and
VIH specifications, the capacitance will not exceed 20 pF.

NOTE:
Keep oscillator components close to chip and use
short, direct traces to XTAL1, XTAL2 and VSS. When
using crystals, C1 e 20 pF, C2 e 20 pF. When using
ceramic resonators, consult manufacturer for recommended circuitry.

10-BIT A/D CHARACTERISTICS
At a clock speed of 6 MHz or less, the clock prescaler should be disabled. This is accomplished by setting IOC2.4 e 1.
At higher frequencies (greater than 6 MHz) the clock
prescaler should be enabled (IOC2.4 e 0) to allow
the comparator to settle.

The converter is ratiometric, so the absolute accuracy is directly dependent on the accuracy and stability
of VREF. VREF must be close to VCC since it supplies
both the resistor ladder and the digital section of the
converter.

FUNCTIONAL DEVIATIONS
Devices marked with an ‘‘E’’, ‘‘F’’ or ‘‘G’’ have the
following errata.
1. Missed Interrupt on P0.7, EXTINT
Interrupts occurring on P0.7 could be missed since
the INTÐPEND EXTINT bit may not be set. See
techbit MC0893.
2. HSIÐMODE Divide-by-Eight
See Faxback Ý2192
REVISION HISTORY
This data sheet (270909-006) is valid for devices
with an ‘‘E’’, ‘‘F’’ or ‘‘G’’ at the end of the top side
tracking number. Data sheets are changed as new
device information becomes available. Verify with
your local Intel sales office that you have the latest
version before finalizing a design or ordering devices.
The following differences exist between this data
sheet (270909-006) and (270909-005):
1. Removed ‘‘Word Addressable Only’’ from Port 3
and 4 in Table 2.
2. Removed ICC1, active mode current at 3.5 MHz.
This specification is not longer required.
3. Removed TLLYV and TLLGV from waveform diagrams.
4. The HSI errata and CMPL with R0 were removed
as this is now considered normal operation.
5. The HSIÐMODE divide-by-eight errata was added to the known errata section.
The following differences exist between this data
sheet (270909-005) and (270909-004):
1. ITL MAX was b 650 mA (270909-004). Now ITL
MAX is b 800 mA (270909-005).
2. IIL2 was named IIL1 (270909-004). Now IIL2 is
correctly named (270909-005).
3. IIL1 was omitted (270909-004). IIL1 MAX was
added. IIL1 MAX is b 850 mA (270909-005).
4. TLLYV and TLLGV (270909-004) were removed.
These timings are not required in high-speed system designs.
5. An errata was added to the known errata section.
There is a possibility to miss an external interrupt
on P0.7 EXTINT.
The following differences exist between this data
sheet (270909-004) and (270909-003):
1. The
ROM
(80C196KB),
and
ROMless
(83C196KB) were combined with this data sheet
resulting in no specification differences.
2. The description of the prescalar bit for the A/D
has been enhanced.
3. THAHBVMIN was b 15 ns (270909-003). Now
THAHBVMIN is b 20 ns (270909-004).
4. TXHQZMAX was 1 TOSC (270909-003). Now
TXHQZMAX is 2 TOSC (270909-004). This should
have no impact on designs using synchronous
serial mode 0.
5. The change indicators for the 80C196KB are
‘‘E’’, ‘‘F’’ and ‘‘G’’. Previously there was only one
change indicator ‘‘E’’. The change indicator is
used for tracking purposes. The change indicator
is the last character in the FPO number. The FPO
number is the second line on the top side of the
device.
21
8XC196KB/8XC196KB16
The following differences exist between (-003) and
version (-002).
1. The 12 MHz and 16 MHz devices were combined in this data sheet. The 87C196KB 12 MHz
only data sheet (272035-001) is now obsolete.
2. Changes were made to the format of the data
sheet and the SFR descriptions were removed.
3. The -002 version of this data sheet was valid for
devices marked with a ‘‘B’’ or a ‘‘D’’ at the end
of the top side tracking number.
4. The OSCILLATOR errata was removed.
5. An errata was not documented in the -002 data
sheet for devices marked with a ‘‘B’’ or a ‘‘D’’.
This is the DIVIDE DURING HOLD/READY errata. When HOLD or READY is active and DIV/
DIVB is the last instruction in the queue, the divide result may be incorrect.
6. TXCH was changed from Min e 40 ns to Min e
20 ns.
7. TRLCL was changed from Min e 5 ns to Min e
4 ns.
9. IIL1 was changed from Max e b 6 mA to Max e
b 7 mA.
10. THAHBV was changed from Min e b 10 ns to
Min e b 15 ns.
Differences between the -002 and -001 data sheets.
1. The -001 version of this data sheet was valid for
devices marked with a ‘‘C’’ at the end of the top
side tracking number.
2. Added 64L SDIP and 80L QFP packages.
3. Added IIH1.
4. Changed TCHWH Min from b 10 ns to b 5 ns.
5. Changed TCHWH Max from a 10 ns to a 15 ns.
6. Changed TWLWH Min from TOSC b 20 ns to
TOSC b 15 ns.
7. Changed TWHQX Min from TOSC b 10 ns to
TOSC b 15 ns.
8. Changed TWHLH Min from TOSC b 10 ns to
TOSC b 15 ns.
9. Changed TWHLH Max from TOSC a 15 ns to
TOSC a 10 ns.
10. Changed TWHBX Min from TOSC b 10 ns to
TOSC b 15 ns.
11. Changed THVCH Min from 85 ns to 55 ns.
12. Remove THVCH Max.
13. Changed TCLHAL Min from b 10 ns to b 15 ns.
14. Changed TCLHAL Max from 20 ns to 15 ns.
15. Changed TCLBRL Min from b 10 ns to b 15 ns.
16. Changed TCLBRL Max from 20 ns to 15 ns.
17. Changed THAHAX Min from b 10 ns to b 15 ns.
18. Added HSI description to Functional Deviations.
19. Added Oscillator description to Functional Deviations.
