GENERAL DESCRIPTION
The Z86318 is a member of the Z8® MCU family of CMOS
microcontrollers. This device offers on-board pull-up and
pull-down resistors (ROM mask-option programmable on a
nibble basis), a scalable trip-point buffer to accommodate
opto-transistor outputs, and high drive ports capable of up
to 20 mA current sinking per pin (3 pins maximum).
The Z86318 features I/O Ports (IOL = 20 mA at VOL =
0.8V, 3 pins max.) to provide increased current sinking ca-
pabilities. These devices also offer users a selection of
ROM mask options, which include a permanently enabled
Watch-Dog Timer that ensures operational reliability
across a broad range of application environments.
For applications requiring powerful I/O capabilities, the
Z86318 provides dedicated input and output lines that are
grouped into three ports. These ports can be configured by
means of ROM mask options (nibble-programmable) as
pull ups, pull downs, or neither. There are two basic ad-
dress spaces available. Program Memory, and 124 bytes
of general-purpose registers.
The Z86318 devices provide two on-chip 8-bit programma-
ble counter/timers with a large number of user-selectable
modes. Each counter/timer is driven by its own 6-bit pro-
grammable prescaler. The Z86318 counter/timers off-load
system real-time tasks such as counting/timing and in-
put/output data communications for increased system effi-
ciency.
Notes: All Signals with a preceding front slash, “/”, are ac-
tive Low, e.g.; B//W (WORD is active Low); /B/W (BYTE is
active Low, only).

Note:
*The Z86318 is functional to VLV voltage. The minimum operational VDD is determined by the value of the VLV voltage at
ambient temperature. The VLV voltage increases as temperature decreases.
