Overview

Z8 Encore! XP® 4K Series

Product Specification

Non-Volatile Data Storage

The non-volatile 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.

Internal Precision Oscillator

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

nal components.

Crystal Oscillator

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

external crystal, ceramic resonator or RC network.

10-Bit Analog-to-Digital Converter

The optional analog-to-digital converter (ADC) converts an analog input signal to a 10-bit

binary number. The ADC accepts inputs from eight different analog input pins in both sin-

gle-ended and differential modes. The ADC also features a unity gain buffer when high

input impedance is required.

Low-Power Operational Amplifier

The optional low-power operational amplifier (LPO) is a general-purpose amplifier prima-

rily targeted for current sense applications. The LPO output may be routed internally to the

ADC or externally to a pin.

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.

Temperature Sensor

The optional Temperature Sensor produces an analog output proportional to the device

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