TMS320F28335PGFA

The TMS320F28335PGFA from Texas Instruments is a C2000™ Delfino™ real-time microcontroller integrating a 32-bit C28x DSP core with a single-precision floating-point unit, architected for closed-loop control applications. Operating at 150 MHz, the device provides 512 KB of embedded Flash memory and extensive integrated control peripherals, including high-resolution pulse-width modulators, a 12-bit analog-to-digital converter with up to 16 channels, and multiple communication interfaces such as CAN, SPI, I2C, and SCI. Its advanced interrupt management, fast context switching, and dedicated math acceleration enable tight real-time performance in digital power conversion, motor control, and sensing systems, all within a 176-pin LQFP footprint.

Typical end uses span industrial servo drives, solar and wind inverter systems, uninterruptible power supplies, and automotive electric powertrain subsystems. The microcontroller is also deployed in high-reliability aerospace and defense platforms where deterministic control and signal processing are critical, including actuation, power management, and avionics feedback loops. From a procurement perspective, this part is generally supplied in industrial and automotive temperature grades, with Texas Instruments’ product longevity program supporting sustained availability for extended life cycles; however, designers targeting military or space-grade applications should verify qualification status, as the commercial PGFA suffix does not guarantee compliance with full MIL-STD screening. Long lead times and global allocation constraints can influence supply planning, making preferred sourcing channels and lifecycle monitoring advisable for production continuity.
