Z86C84

The Z86C83/C84 Z86C84 Consumer Controller Processors (CCP™ ) are full-featured members of the CMOS Z8 microcontroller family offering a unique register-to-register architecture that avoids accumulator bottlenecks for higher code efficiency than RISC processors.

The Z86C83/C84 Z86C84 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 Z86C84 can prioritize six different maskable, vectored, internal or external interrupts for efficient interrupt handling and multitasking functions.
