Product details

What this DSP brings to a real-time control loop

The Texas Instruments TMS320F2811PBKA is a 32-bit fixed-point C28x DSP clocked at 150 MHz, with 256 KB of Flash program memory and 18K x 16 words of RAM. It is AEC-Q100 qualified for automotive applications, making it a fit for under-hood motor control, powertrain, and power conversion designs where deterministic loop timing matters. The 150 MHz core delivers a single-cycle 32×32-bit multiply-accumulate — the throughput needed for sensorless field-oriented control or digital power loops without an external FPGA.

At 150 MHz, the C28x executes a 32-bit MAC in one clock cycle. The fixed-point architecture requires Q-format scaling.

Surface-mount assembly is straightforward with lead-free reflow profiles.

Frequently asked questions

What is the difference between TMS320F2811PBKA and TMS320F2812PBKA?

The TMS320F2812PBKA typically offers a larger Flash memory (256 KB vs 128 KB) and additional RAM, but both share the same 150 MHz C28x core, 128-LQFP package, and AEC-Q100 qualification. The F2811PBKA is the lower-density variant for cost-sensitive designs where 256 KB Flash suffices.

What is the pinout of TMS320F2811PBKA?

The TMS320F2811PBKA uses a 128-pin LQFP (14x14 mm) with 56 general-purpose I/O. The pinout is documented in the official TI datasheet, which we can provide upon request.
