PIN DESCRIPTIONS
Symbol
Name and Function
VCC
Main supply voltage (a5V)
VSS VSS VSS
Digital circuit ground (0V) There are three VSS pins all of which MUST be
connected to a single ground plane
VREF
Reference for the AD converter (a5V) VREF is also the supply voltage to the
analog portion of the AD converter and the logic used to read Port 0 Must be
connected for AD and Port 0 to function
VPP
Programming voltage for the EPROM parts It should be a125V for
programming It is also the timing pin for the return from powerdown circuit
Connect this pin with a 1 mF capacitor to VSS anda1MX resistor to VCC If this
function is not used VPP may be tied to VCC
ANGND
Reference ground for the AD converter Must be held at nominally the same
potential as VSS
XTAL1
Input of the oscillator inverter and the internal clock generator
XTAL2
Output of the oscillator inverter
P27CLKOUT
Output of the internal clock generator The frequency is
the oscillator
frequency It has a 50% duty cycle Also LSIO pin
RESET
Reset input to the chip Input low for at least 16 state times will reset the chip The
subsequent low to high transition resynchronizes CLKOUT and commences a 10-
state time sequence in which the PSW is cleared bytes are read from 2018H and
201AH loading the CCBs and a jump to location 2080H is executed Input high for
normal operation RESET has an internal pullup
P57BUSWIDTH
Input for bus width selection If CCR bit 1 is a one and CCR1 bit 2 is a one this pin
dynamically controls the Bus width of the bus cycle in progress If BUSWIDTH is
low an 8-bit cycle occurs If BUSWIDTH is high a 16-bit cycle occurs If CCR bit 1
is ‘‘0’’ and CCR1 bit 2 is ‘‘1’’ all bus cycles are 8-bit if CCR bit 1 is ‘‘1’’ and CCR1
bit 2 is ‘‘0’’ all bus cycles are 16-bit CCR bit 1 e ‘‘0’’ and CCR1 bit 2 e ‘‘0’’ is
illegal Also an LSIO pin when not used as BUSWIDTH
NMI
A positive transition causes a non-maskable interrupt vector through memory
location 203EH Used by Intel (GND this pin)
P51INST
Output high during an external memory read indicates the read is an instruction
fetch INST is valid throughout the bus cycle INST is active only during external
memory fetches during internal EP ROM fetches INST is held low Also LSIO
when not INST
EA
Input for memory select (External Access) EA equal to a high causes memory
accesses to locations 2000H through 5FFFH to be directed to on-chip EPROM
ROM EA equal to a low causes accesses to these locations to be directed to off-
chip memory EA ea125V causes execution to begin in the Programming
Mode EA latched at reset
P50ALEADV
Address Latch Enable or Address Valid output as selected by CCR Both pin
options provide a latch to demultiplex the address from the addressdata bus
When the pin is ADV it goes inactive (high) at the end of the bus cycle ADV can
be used as a chip select for external memory ALEADV is active only during
external memory accesses Also LSIO when not used as ALE
