CPU and Peripheral Overview

Z8 Encore! XP® F082A Series

Product Specification

Internal Precision Oscillator

The internal precision oscillator (IPO) is a trimmable clock source that requires no exter-

nal components.

Temperature Sensor

The optional temperature sensor produces an analog output proportional to the device tem-

perature. This signal can be sent to either the ADC or the analog comparator.

Analog Comparator

The analog comparator compares the signal at an input pin with either an internal pro-

grammable voltage reference or a second input pin. The comparator output can be used to

drive either an output pin or to generate an interrupt.

External Crystal Oscillator

The crystal oscillator circuit provides highly accurate clock frequencies with the use of an

external crystal, ceramic resonator or RC network.

Low Voltage Detector

The low voltage detector (LVD) is able to generate an interrupt when the supply voltage

drops below a user-programmable level. The LVD is available on 8-pin devices only.

On-Chip Debugger

The Z8 Encore! XP F082A Series products feature an integrated on-chip debugger (OCD)

accessed via a single-pin interface. The OCD provides a rich-set of debugging capabilities,

such as reading and writing registers, programming Flash memory, setting breakpoints and

executing code.

Universal Asynchronous Receiver/Transmitter

The full-duplex universal asynchronous receiver/transmitter (UART) is included in all Z8

Encore! XP package types. The UART supports 8- and 9-bit data modes and selectable

parity. The UART also supports multi-drop address processing in hardware. The UART

baud rate generator (BRG) can be configured and used as a basic 16-bit timer.

Timers

Two enhanced 16-bit reloadable timers can be used for timing/counting events or for

motor control operations. These timers provide a 16-bit programmable reload counter and
