TMS320F28335PGFA

Texas Instruments C2000™ Delfino™ — 32-Bit Digital Signal Controller, 150 MHz with Floating-Point Unit

Product Overview

The TMS320F28335PGFA is a high-performance 32-bit digital signal controller (DSC) from Texas Instruments' C2000™ Delfino™ family. Built on a 150 MHz C28x CPU with an integrated hardware IEEE-754 single-precision Floating-Point Unit (FPU), it delivers 150 MIPS of real-time processing throughput for closed-loop control applications. The device packs 512 KB of on-chip Flash memory and 68 KB of RAM, a 16-channel 12-bit ADC with 80 ns conversion time, 18 PWM outputs (6 with high-resolution 150 ps micro-step control), and a rich peripheral set including CAN 2.0B, SPI, I2C, SCI/UART, McBSP, and a 16/32-bit External Memory Interface (EMIF). Housed in a compact 176-pin LQFP (24×24 mm) package and rated for the full industrial temperature range (−40°C to +85°C), the TMS320F28335PGFA is engineered for demanding motor drives, digital power conversion, renewable energy systems, and advanced industrial automation.

Applications

Why Choose TMS320F28335PGFA

The C2000 Delfino series has been the de-facto standard for real-time closed-loop control for over a decade. Unlike general-purpose MCUs that require software floating-point libraries (slow, non-deterministic), the TMS320F28335PGFA executes single-precision floating-point math in hardware — one instruction per clock cycle. This means complex algorithms like Park/Clarke transforms, PID loops with anti-windup, and sensorless FOC (Field-Oriented Control) run with deterministic timing, critical for motor control and power conversion where a few microseconds of jitter can cause instability. The on-chip 12-bit ADC's dual sample-and-hold and 80 ns conversion time enable simultaneous current and voltage sensing without external ADCs. Combined with the 150 ps high-resolution PWM, this chip can directly drive GaN and SiC power stages in modern high-frequency converters. With a mature ecosystem — Code Composer Studio IDE, controlSUITE libraries, TI's Digital Power and Motor Control SDKs — development time is measured in weeks, not months.
