Module 2: Pin Strapping failures due to 1.8V core power slow ramp-up

DESCRIPTION

A small percentage (<1%) of devices can potentially encounter pin strapping failures with fast 3.3V supply rise times

(<150us) or slow core rail rise times, due to a large bulk storage capacitor value (10uF or greater) for the 1.8V core.

END USER IMPLICATIONS

When this errata occurs, pin strap values may not be correctly latched.

Work around

Reduce the 1.8V core bulk storage capacitor from 10uF to 1.0uF and ensure the 3.3V supply rise time is 250us

or greater.

PLAN

This errata is not planned to be corrected in a future revision.
