Z86C83

The Z86C83/C84 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 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.
