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.
