Overview
TMS320F28064PNT from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and advanced motor control peripherals including 14 ePWM channels (7 HRPWM-capable), 3 eCAP modules, 2 eQEP modules, and a 12-bit 3.46-MSPS ADC - designed for closed-loop digital power and motor drive applications such as solar inverters and servo drives.
For engineers reviewing the TMS320F28064PNT datasheet, TMS320F28064PNT pinout, TMS320F28064PNT application, or TMS320F28064PNT equivalent, key selection criteria include its 14-channel ePWM count, 54 GPIOs with input filtering, 64KB on-chip Flash, 34KB SARAM, and support for InstaSPIN-FOC™ firmware acceleration in high-precision motion control systems.
Technical Context
The TMS320F28064PNT implements a Harvard-architecture C28x CPU with atomic instruction execution, unified memory model, and hardware-accelerated floating-point math via dedicated FPU and CLA cores. Its peripheral set is optimized for deterministic real-time control: ePWM modules support dual-edge modulation and trip-zone protection, while the ADC features dual sample-and-hold and ratio-metric reference support for precision current sensing.
System-level integration includes two internal zero-pin oscillators, programmable PLL, watchdog timer, and missing-clock detection. The device supports single 3.3-V supply operation with integrated POR/BOR and voltage regulator, eliminating external sequencing requirements - critical for cost-sensitive industrial power electronics designs.
