GENERAL DESCRIPTION
The Z8602 Keyboard Controller (KBC
of sophistication to single-chip architecture. The Z8602 is a
member of the Z8 single-chip microcontroller family with 2
Kbytes of ROM.
The Z8602 KBC is housed in a 40-lead DIP, and is manufactured
in NMOS technology. Zilog’s microcontroller offers fast execu-
tion, more efficient use of memory, more sophisticated interrupt,
input/output bit-manipulation capabilities, and easy hardware/
software system expansion along with low cost and low power
consumption.
The KBC architecture is characterized by a flexible I/O scheme,
an efficient register, I/O, and a number of ancillary features that
are useful in many industrial and advanced scientific applica-
tions.
The device applications demand powerful I/O capabilities. The
KBC fulfills this with 32-pins dedicated to input and output.
These lines are grouped into four ports, each port consists of 8
lines, and are configurable under software control to provide
timing, status signals, and serial or parallel I/O ports.

The Z8602 offers low EMI emission achieved by means of
several modifications in the output drivers and clock circuitry of
the device.
There are two basic address spaces available to support this wide
range of configurations: Program Memory and 124 General-
Purpose Registers.
The KBC offers two on-chip counter/timers with a large number
of user selectable modes. This unburdens the program from
coping with real-time problems such as counting/timing.
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).
