Introduction

1.5.40

Voltage regulator / Power Management Unit (PMU)

The on-chip voltage regulator module provides the following features:



Single external rail required



Single high supply required: nominal 3.3 V both for packaged and Known Good Die

option

–

Packaged option requires external ballast transistor due to reduced dissipation

capacity at high temperature but can use embedded transistor if power dissipation

is maintained within package dissipation capacity (lower frequency of operation)

–

Known Good Die option uses embedded ballast transistor as dissipation capacity

is increased to reduce system cost



All I/Os are at same voltage as external supply (3.3 V nominal)



Duplicated Low-Voltage Detectors (LVD) to guarantee proper operation at all stages

(reset, configuration, normal operation) and, to maximize safety coverage, one LVD

can be tested while the other operates (on-line self-testing feature)

1.5.41

Built-In Self-Test (BIST) capability

This device includes the following protection against latent faults:



Boot-time Memory Built-In Self-Test (MBIST)



Boot-time scan-based Logic Built-In Self-Test (LBIST)



Run-time ADC Built-In Self-Test (BIST)



Run-time Built-In Self Test of LVDs
