GENERAL DESCRIPTION

The Z08617 Keyboard Controller is a member of the

Z8® single-chip microcontroller family with 4 Kbytes

of ROM. The device is housed in a 40-pin DIP package,

and is manufactured in NMOS technology. The Z08617

microcontroller offers fast execution, efficient use of

memory, sophisticated interrupt, input/output bit-

manipulation capabilities, and easy hardware/soft-

ware system expansion along with low cost and low

power consumption.

The Z08617 architecture is characterized by a flex-

ible I/O scheme, an efficient register, I/O, and a

number of ancillary features that are useful in many

industrial and advanced scientific applications.

For applications which demand powerful I/O capabili-

ties, the Z08617 provides 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 Z08617 offers low EMI emission which is achieved

by means of several modifications in the output

drivers and clock circuitry of the device.

There are two basic address spaces which are avail-

able to support this wide range of configurations:

Program Memory and 124 General-Purpose Registers.

The Z08617 offers two on-chip counter/timers with

a large number of user-selectable modes. This unbur-

dens the program from coping with real-time prob-

lems such as counting/timing (Figure 1).

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).
