GENERAL DESCRIPTION
The Z86C83/C84 Consumer Controller Processors
(CCP
™
) are full-featured members of the CMOS Z8 micro-
controller family offering a unique register-to-register ar-
chitecture that avoids accumulator bottlenecks for higher
code efficiency than RISC processors.
The Z86C83/C84 are designed to be used in a wide variety
of embedded control applications, such as appliances,
process controls, keyboards, security systems, battery
chargers, and automotive modules.
For applications requiring powerful I/O capabilities, the
Z86C83/C84 devices can have up to 21/17 (C83/C84
respectively) pins dedicated to input and output. These
lines are grouped into three ports, and are configured by
software to provide digital/analog I/O timing and status
signals.
An on-chip, half-flash 8-bit
±
1/2 Least Significant Bit (LSB)
A/D converter can multiplex up to eight analog inputs.
Unused analog inputs revert to standard digital I/O use.
Unique, programmable A
GND
offset control of the A/D
resistor ladder compresses the converter's dynamic range
for maximum effective 9-bit A/D resolution.
The Z86C84 has two 8-bit
±
1/2 LSB D/A converters. High
and low reference voltages provide precise control of the
output voltage range. Programmable gain for each D/A
converter provides a maximum effective 10-bit resolution
for many tasks.
On-chip 8-bit counter/timers with many user-selectable
modes simplify real-time tasks, such as counting, timing,
and generation of PWM signals.
The designer can prioritize six different maskable,
vectored, internal or external interrupts for efficient
interrupt handling and multitasking functions.

GENERAL DESCRIPTION
(Continued)
By means of an expanded register file, the designer has
access to additional control registers for configuring per-
ipheral functions including the A/D and D/A converters,
counter/timers, and I/O port functions (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).

Notice:
Stresses greater than those listed under Absolute
Maximum Ratings may cause permanent damage to the
device. This is a stress rating only; functional operation of
the device at any condition above those indicated in the
operational sections of these specifications is not implied.
Exposure to absolute maximum rating conditions for an
extended period may affect device reliability.
Total power dissipation should not exceed 770 mW for the
package. Power dissipation is calculated as follows:
Total Power Dissipation =
