TMS320VC5509A Silicon Errata
1
Introduction
This document describes the silicon updates to the functional specifications for the TMS320VC5509A. The updates
are applicable to:
•
TMS320VC5509A (144-pin LQFP, PGE suffix)
•
TMS320VC5509A (179-pin MicroStar BGA, GHH suffix)
The advisory numbers in this document are not always sequential. Some advisory numbers have been removed as
they do not apply to the device revisions specified in this document. When items are moved or deleted, the remaining
numbers remain the same and are not resequenced.
Issues related to CPU operation are documented in the TMS320C55x DSP CPU Programmer's Reference
Supplement (literature number SPRU652).

Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP
devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS
(e.g., TMS320VC5509A). 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 (TMX / TMDX) through fully qualified production devices/tools (TMS / TMDS).
Device development evolutionary flow:
TMX
Experimental device that is not necessarily representative of the final device's electrical specifications
TMP
Final silicon die that conforms to the device's electrical specifications but has not completed quality and
reliability verification
TMS
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
TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS 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 ( TMX or TMP) 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.
