Silicon Errata
SPRZ357J–August 2011–Revised July 2014
F28M35x Concerto™ MCU Silicon Errata
1 Introduction
This document describes the silicon updates to the functional specifications for the F28M35x
microcontrollers (MCUs).
The updates are applicable to:
• 144-pin PowerPAD™ Thermally Enhanced Thin Quad Flatpack, RFP Suffix
2 Device and Development Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
Concerto MCU devices and support tools. Each Concerto MCU commercial family member has one of
three prefixes: x, p, or no prefix (for example, xF28M35H52C1RFPT). Texas Instruments recommends
two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent
evolutionary stages of product development from engineering prototypes (with prefix x for devices and
TMDX for tools) through fully qualified production devices and tools (with no prefix for devices and TMDS
for tools).
xF28M35... Experimental device that is not necessarily representative of the final device's
electrical specifications
pF28M35... Final silicon die that conforms to the device's electrical specifications but has
not completed quality and reliability verification
F28M35... Fully qualified production device
Support tool development evolutionary flow:
TMDX Development-support product that has not yet completed Texas Instruments internal
qualification testing
TMDS Fully qualified development-support product
Devices with prefix x or p and TMDX development-support tools are shipped against the following
disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices and TMDS development-support tools have been characterized fully, and the quality
and reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices with prefix of x or p have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate still is undefined. Only qualified production devices are
to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, RFP) and temperature range (for example, T).
