Dual-core C28x DSP for real-time control at 200 MHz
The TMS320F28374DPTPT is a dual-core 32-bit C28x digital signal controller clocked at 200 MHz. On-chip data converters integrate 20 channels of 12-bit ADC and three 12-bit DACs, enough to sample phase currents, DC-link voltage, and rotor position without external analog front-ends in many designs. The 97 GPIOs and connectivity suite — CAN, I²C, SPI, UART, USB, McBSP, and the Universal Parallel Port (uPP) — cover industrial fieldbus bridging and high-speed data offload to an FPGA or external ADC.
Lifecycle and sourcing — what the record shows
Analog integration — 20 ADC channels and 3 DAC outputs
The 20-channel 12-bit ADC can sample all three motor phase currents, the DC-link voltage, and multiple temperature sensors in a single conversion sequence. The three 12-bit DACs can output analog reference voltages or feed a compensation ramp into an external comparator — useful for peak-current-mode control without extra components.
