This document describes the silicon updates to the functional specifications for the TMS320F2802x and TMS320F2802xx microcontrollers (MCUs).

The updates are applicable to:

• 38-pin Thin Shrink Small-Outline Package, DA Suffix
• 48-pin Low-Profile Quad Flatpack, PT Suffix

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all [TMS320] DSP devices and support tools. Each TMS320™ DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (for example, TMS320F28027). 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).

Support tool development evolutionary flow:

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.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, DA) and temperature range (for example, T).

Figure 3-1 and Figure 3-2 provide examples of the 2802x device markings and define each of the markings. The silicon revision can be determined by the symbols marked on the top of the package as shown in Figure 3-1 and Figure 3-2 (see Table 3-1). Some prototype devices may have markings different from those illustrated. Figure 3-3 and Figure 3-4 show the device nomenclature.
