GENERAL DESCRIPTION

The Z86C83/C84 Consumer Controller Processors

(CCP

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

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.
