Automotive-grade real-time control MCU — now obsolete
The TMS320F28332PTPQ is a 32-bit C28x Delfino microcontroller from Texas Instruments, rated for automotive applications with AEC-Q100 qualification. It runs at 100 MHz, carries 128 KB of Flash and 26K x 16 of RAM, and operates across the full -40°C to 125°C temperature range. The 176-pin HLQFP package with exposed pad supports surface-mount assembly and thermal dissipation in motor-drive and inverter designs.
100 MHz — enough for time-critical loops
The 100 MHz core speed on this C28x DSP-class MCU means it can handle nested control loops and PWM updates at microsecond intervals — typical for automotive inverter and DC-DC converter stages. The 88 GPIOs and integrated CAN, SPI, and SCI peripherals give it the I/O headroom for sensor fusion and actuator interfaces without external expanders.
AEC-Q100 — built for under-hood and chassis
The internal oscillator and POR reduce external BOM count in space-constrained ECU designs.
