GENERAL DESCRIPTION
The Z86193 is a CMOS ROMless Z8
®
microcontroller
enhanced with a hardwired 16-bit x 16-bit multiplier,
32-bit/16-bit divider, three 16-bit counter/timers, search
and merge instructions, Evaluation mode and a Bus
Request mode. The device is code compatible with other
Z8 family devices, yet it offers more powerful mathematical
capabilities, data searching capabilities, and bit manipu-
lation. The Z86193 is offered in a 64-pin VQFP package.
The Z86193 provides up to 16 output address lines permit-
ting an address space of up to 64 Kbytes each of Program
or Data memory. Eight address outputs are provided by a
de-multiplexed 8-bit Address Bus (A7-A0) or by a multi-
plexed 8-bit Address/Data Bus (AD7-AD0). The remaining
eight address lines (A15-A8) can be provided by the
software configuration of Port0 to output address.
The Z86193 includes a bus which differs from other Z8
devices. The Z86193 provides bus control signals /RD
(Read Strobe), /WR (Write Strobe), and ALE (Address
Latch Enable).
There are 464 8-bit registers located on-chip and orga-
nized as 444 general-purpose registers, 16 control and
status registers, one reserved register, and up to three I/O
port registers. The Register File is partitioned into two
Register Pages. Page0 contains 208 registers and Page1
contains 208 registers. The 48 other registers are common
to both Register Pages. The Register file is also divided into
29 working register groups of 16 registers each. Configu-
ration of the registers in this format allows the use of short
format instructions. There are 17 additional registers imple-
mented in the Expanded Register file in Banks D and E.
Two of the registers may be used as general-purpose,
while the other 15 are used to supply data and control
for the multiplier/divider unit and the additional
counter/timers.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.:
B//W (WORD is active Low); /B/W (BYTE is active Low, only).

Stress greater than those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This
is a stress rating only; operation of the device at any
condition above those indicated in the operational sec-
tions of these specifications is not implied. Exposure to
absolute maximum rating conditions for an extended pe-
riod may affect device reliability.
