90 MHz C28x core — what it buys the control loop
The TMS320F28063PNT is a 32-bit single-core C28x DSP microcontroller from Texas Instruments running at 90 MHz. It carries 128 KB of on-chip flash and 34K x 16 of RAM, enough to run a field-oriented motor-control or digital-power loop without external memory. The 80-LQFP package (12x12 mm) is a common footprint that can be hand-soldered in a pinch — no hot-air station required, which matters when you are swapping one in the field.
Industrial temp range and on-chip peripherals
The peripheral set includes CAN, I²C, SPI, UART, and McBSP for serial communication, plus a 12-channel 12-bit ADC, PWM timers, and a watchdog timer — all the blocks you need for a single-chip motor drive or a digital power supply controller.
TI lists the TMS320F28063PNT as Active. That means no last-time-buy clock ticking, no end-of-life notice looming.
