The 34K x 16 RAM is split across multiple SARAM blocks, which lets the linker place time-critical variables and lookup tables without contention from DMA transfers. The 16-channel 12-bit ADC sequences conversions in the background while the C28x executes the control law.
The C28x core runs at 90 MHz, which is the clock rate that determines PWM update frequency and ADC conversion throughput in real-time control loops.
It belongs to the C2000 C28x Piccolo series, a family of 32-bit microcontrollers optimized for real-time control in motor drives, digital power, and industrial automation.
