Product Specification

Pin Description

Overview

The Z8 Encore! XP® F08xA Series products are available in a variety of packages styles

and pin configurations. This chapter describes the signals and available pin configurations

for each of the package styles. For information regarding the physical package specifica-

tions, refer to the chapter “Packaging” on page 206.

Available Packages

Table 2 identifies the package styles that are available for each device in the Z8 Encore!

XP® F08xA Series product line.

Pin Configurations

Figures 2 and 4 illustrate the pin configurations for all of the packages available in the Z8

Encore! XP® F08xA Series. Refer to Table 3 for a description of the signals. The analog

input alternate functions (ANAx) are not available on the Z8F081A devices. The analog

supply pins (AVDD and AVSS) are also not available on these parts, and are replaced by

PB6 and PB7.

At reset, all Port A, B and C pins default to an input state. In addition, any alternate func-

tionality is not enabled, so the pins function as general purpose input ports until pro-

grammed otherwise. At powerup, the Port D0 pin defaults to the RESET alternate

function.

The pin configurations listed are preliminary and subject to change based on manufactur-

ing limitations.
