Kbytes
stated
factory programmed ROM
In this documeDntatthaeS8h0eCe19t46UKC.cwoilml refer to all products unless
otherwise
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 tem-
perature range of 0 C to a70 C With the extended (Express) temperature range option operational charac-
teristics are guaranteed over the temperature range of b40 C to a85 C Unless otherwise noted the specifi-
cations are the same for both options

Name and Function
Main supply voltage (5V)
Digital circuit ground (0V) There are multiple VSS pins all of which must be connected
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
Reference ground for the A D converter Must be held at nominally the same potential as
VSS
Timing pin for the return from powerdown circuit This pin also supplies the programming
voltage on the EPROM device
Input of the oscillator inverter and of the internal clock generator
Output of the oscillator inverter
Output of the internal clock generator The frequency of CLKOUT is the oscillator
frequency
Reset input and open drain output
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
A positive transition causes a vector through 203EH
Output high during an external memory read indicates the read is an instruction fetch INST
is valid throughout the bus cycle INST is activated only during external memory accesses
and output low for a data fetch
Input for memory select (External Access) EA equal high causes memory accesses to
locations 2000H through 5FFFH to be directed to on-chip ROM EPROM EA equal to low
causes accesses to those locations to be directed to off-chip memory Also used to enter
programming mode

ADV it goes inactive high at the end of the bus cycle ALE ADV is activated only during
external memory accesses
Read signal output to external memory RD is activated only during external memory reads
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
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 written BHE WRH is activated only during external
memory writes
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
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
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
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
8-bit quasi-bidirectional I O port
8-bit multi-functional port All of its pins are shared with other functions in the 80C196KC
Pins 2 6 and 2 7 are quasi-bidirectional
