M80C186EB
Table 4. M80C186EB Pin Descriptions
Name
Type
Description
V
CC
POWER
connections consist of four pins which must be shorted
externally to a V
CC
board plane.
V
SS
GROUND
connections consist of six pins which must be shorted
externally to a V
SS
board plane.
CLKIN
I
CLocK INput
is an input for an external clock. An external oscillator
operating at two times the required M80C186EB operating frequency
can be connected to CLKIN. For crystal operation, CLKIN (along with
OSCOUT) are the crystal connections to an internal Pierce oscillator.
A(E)
OSCOUT
O
OSCillator OUTput
is only used when using a crystal to generate the
external clock. OSCOUT (along with CLKIN) are the crystal
connections to an internal Pierce oscillator. This pin is not to be used
as 2X clock output for non-crystal applications (i.e., this pin is N.C. for
non-crystal applications). OSCOUT does not float in ONCE mode.
H(Q)
R(Q)
P(Q)
CLKOUT
O
CLocK OUTput
provides a timing reference for inputs and outputs of
the processor, and is one-half the input clock (CLKIN) frequency.
CLKOUT has a 50% duty cycle and transistions every falling edge of
CLKIN.
H(Q)
R(Q)
P(Q)
RESIN
I
RESet IN
causes the M80C186EB to immediately terminate any bus
cycle in progress and assume an initialized state. All pins will be
driven to a known state, and RESOUT will also be driven active. The
rising edge (low-to-high) transition synchronizes CLKOUT with CLKIN
before the M80C186EB begins fetching opcodes at memory location
0FFFF0H.
A(L)
RESOUT
O
RESet OUTput
that indicates the M80C186EB is currently in the
reset state. RESOUT will remain active as long as RESIN remains
active.
H(0)
R(1)
P(0)
PDTMR
I/O
A(L)
H(WH)
R(Z)
P(1)
Power-Down TiMeR
pin (normally connected to an external
capacitor) that determines the amount of time the M80C186EB waits
after an exit from power down before resuming normal operation. The
duration of time required will depend on the startup characteristics of
the crystal oscillator.
NMI
I
Non-Maskable Interrupt
input causes a TYPE-2 interrupt to be
serviced by the CPU. NMI is latched internally.
A(E)
TEST/BUSY
I
TEST
is used during the execution of the WAIT instruction to
suspend CPU operation until the pin is sampled active (LOW). TEST
is alternately known as BUSY when interfacing with an M80C187
numerics coprocessor.
A(E)
AD15:0
I/O
S(L)
H(Z)
R(Z)
P(X)
These pins provide a multiplexed
Address
and
Data
bus. During the
address phase of the bus cycle, address bits 0 through 15 are
presented on the bus and can be latched using ALE. 8- or 16-bit data
information is transferred during the data phase of the bus cycle.
A18:16
A19/ONCE
These pins provide multiplexed
Address
during the address phase of
the bus cycle. Address bits 16 through 19 are presented on these
pins and can be latched using ALE. These pins are driven to a logic 0
during the data phase of the bus cycle. During a processor reset
(RESIN active), A19/ONCE is used to enable ONCE mode. A18:16
must not be driven low during reset or improper M80C186EB
operation may result.
