GENERAL DESCRIPTION
The Z86418 is a member of the Z8
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 10 mA current sinking per pin (3 pins maximum).
MCU family of CMOS
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
Z86418 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 125 bytes
of general-purpose registers.
The Z86418 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 Z86418 counter/timers off-load
system real-time tasks such as counting/timing and in-
put/output data communications for increased system effi-
ciency.
Note:
example: B/W, in which WORD is active Low; or B/W, in
which BYTE is active Low.
All Signals with an overline, “ ”, are active Low. For
