What this part is and where it fits
The TMS320F28378SPTPS is a 32-bit C28x Delfino microcontroller from Texas Instruments, built for real-time control in motor drives, digital power, and industrial servo applications. It runs at 200 MHz on a single C28x core, with 1 MB of Flash program memory and 82K x 16 of RAM.
Mixed-signal converters on-chip
Twenty 12-bit ADCs and nine 16-bit ADCs plus a single 12-bit DAC are integrated. That covers three-phase current sensing (two ADCs per phase for offset cancellation), a DC-link voltage measurement, and an analog output for a torque command or analog tachometer — all without external ADC chips. The 16-bit converters handle the precision channel for resolver-to-digital or strain-gauge readout.
Connectivity and I/O for fieldbus and sensor links
CAN, USB, SPI, I²C, McBSP, SCI, UART/USART, and a uPP (universal parallel port) are all on the peripheral list. That means you can hang a CANopen fieldbus, a USB service port, and a high-speed SPI ADC on the same die without external bridge chips. The 97 GPIOs leave room for encoder inputs, relay drivers, and panel LEDs.
