CPU and Peripheral Overview

Z8 Encore! XP® F082A Series

Product Specification

operate in ONE-SHOT, CONTINUOUS, GATED, CAPTURE, CAPTURE RESTART,

COMPARE, CAPTURE and COMPARE, PWM SINGLE OUTPUT and PWM DUAL

OUTPUT modes.

General-Purpose Input/Output

The Product Line MCUs feature 6 to 25 port pins (Ports A–D) for general- purpose input/

output (GPIO). The number of GPIO pins available is a function of package and each pin

is individually programmable. 5 V tolerant input pins are available on all



I/Os on 8-pin devices and most I/Os on other package types.

Direct LED Drive

The 20- and 28-pin devices support controlled current sinking output pins capable of driv-

ing LEDs without the need for a current limiting resistor. These LED drivers are indepen-

dently programmable to four different intensity levels.

Flash Controller

The Flash Controller programs and erases Flash memory. The Flash Controller supports

several protection mechanisms against accidental program and erasure, plus factory serial-

ization and read protection.

Non-Volatile Data Storage

The nonvolatile data storage (NVDS) uses a hybrid hardware/software scheme to imple-

ment a byte programmable data memory and is capable of over 100,000 write cycles.

Devices with 8KB of Flash memory do not include the NVDS feature.

Interrupt Controller

The Z8 Encore! XP F082A Series products support up to 20 interrupts. These interrupts

consist of 8 internal peripheral interrupts and 12 general-purpose I/O pin interrupt sources.

The interrupts have three levels of programmable interrupt priority.

Reset Controller

The Z8 Encore! XP F082A Series products can be reset using the RESET pin, Power-On

Reset, Watchdog Timer (WDT) time-out, STOP Mode exit, or Voltage Brown-Out (VBO)
