Key Features
- 200 MHz C28x CPU with IEEE 754 single-precision floating-point unit for real-time control algorithms without software emulation overhead
- 512 KB flash and integrated ADC, DAC, and DMA channels enabling complete power converter control on a single chip
- 100-pin HTQFP (14x14 mm) package with JTAG boundary scan for in-circuit debugging and production test
Applications
The TMS320F28374SPZPS is optimized for digital power supply control, three-phase motor drives, and solar inverter designs where fast ADC sampling and floating-point PID loops must execute within a few microseconds per control cycle. Its integrated DAC and DMA channels minimize latency between sensing and actuation, making it a leading choice for grid-tied inverters, servo controllers, and UPS systems demanding sub-microsecond interrupt response at 200 MHz.

Frequently Asked Questions
What CPU performance does TMS320F28374SPZPS deliver and how does floating-point support benefit motor control firmware?
The TMS320F28374SPZPS runs its C28x core at 200 MHz and includes a hardware IEEE 754 single-precision floating-point unit. This allows PID controllers, Park and Clarke transforms, and space-vector PWM algorithms to execute in floating-point without emulation, reducing control loop latency to under 5 µs for 3-phase motor drive applications compared to fixed-point implementations that require manual scaling.
How much flash memory does TMS320F28374SPZPS provide and how does that constrain firmware complexity?
The TMS320F28374SPZPS integrates 512 KB (256K x 16) of on-chip flash. This is sufficient for a full real-time control application including interrupt service routines, communication stacks such as CAN or SCI, and lookup tables for efficiency maps, while leaving room for calibration data storage — making external flash unnecessary for most digital power converter or servo drive firmware projects.
Which package does TMS320F28374SPZPS use and how does its footprint compare to larger pin-count DSC options?
The TMS320F28374SPZPS is housed in a 100-pin HTQFP package measuring 14 x 14 mm, which is more compact than 176-pin or 337-ball BGA packages used by higher-end C28x devices. It supports JTAG boundary scan for production test, and the exposed-pad thermal design aids heat dissipation at the 200 MHz operating frequency, keeping junction temperature within safe limits at full computational load.
