The 100 MHz clock rate on the C28x fixed-point core delivers the throughput needed for time-critical control loops — think current-loop regulation in a servo drive or switching-cycle management in a digital power supply. The 256 KB Flash holds a substantial firmware image; the 18K x 16 RAM provides working space for lookup tables and data buffers. The 16-channel 12-bit ADC samples multiple analog feedback signals without external muxing, keeping the bill of materials compact.
The TMS320F2809GGMS is marked obsolete per the product status. No official successor is listed in the available records. Buyers should plan for last-time-buy or alternate sourcing strategies if long-term supply is needed.
