4. API Revision vs. Silicon Revision
The silicon revision can be determined by the lot trace code marked on the top of the package. The figure below
provides an example of the TMS320F280x markings. Some prototype devices may have markings different from
those illustrated. Refer to the TMS320F2808, TMS320F2806, TMS320F2802, TMS320F2801, UCD9501 DSP
Silicon Errata (literature number SPRZ171) for information on how to determine your device’s silicon revision.

Previous versions of the SDFlash algorithms are based on Flash APIs that are obsolete and no longer
recommended for use:
API Version 2.00: F2808_API_V200.lib, F2806_API_V200.lib, F2801_API_V200.lib
SDFlash Beta 4 used the V2.00 API. As of revision B silicon, this API will report a
STATUS_FAIL_API_SILICON_MISMATCH error. The flash will not be modified.
API Version 1.00 and earlier: F2808_API_V100.lib, F2806_API_V100.lib, F2801_API_V100.lib
For proper reliability and programming performance these APIs must not be used.

SDFlash V1.0 and earlier do not support the F2802 device. V1.1 is the first version to support the F2802.
