REVISION HISTORY This silicon errata revision history highlights the technical changes made to the SPRZ231 revision to make it an SPRZ231A revision. Scope: Applicable updates to the C64x device family, specifically relating to the DM643 device, have been incorporated. Differences between the actual silicon revisions 2.0 and earlier specification values and the data sheet values specified in the TMS320C643 Video/Imaging Fixed-Point Digital Signal Processor data manual (literature number SPRS269 or higher) have been documented. Updated values for the A-500 (extended temperature) device have also been incorporated. Added the device-specific information supporting the TMS320DM643 silicon revisions 2.0, 1.2, 1.1, and 1.0 devices, which are in the production data (PD) stage of development.
