TMS320F28335PGFA: Texas Instruments C2000 Delfino DSC

The Industry Standard for Motor Control, Power Electronics & Renewable Energ

In precision power control applications, microseconds matter. When a solar inverter needs to track maximum power points in real time, or a servo drive must execute a field-oriented control loop within a single PWM period, only a purpose-built real-time digital signal controller can deliver. The TMS320F28335PGFA from Texas Instruments is exactly that device — the benchmark Digital Signal Controller (DSC) of the C2000 Delfino family that has defined industrial real-time control for over a decade.

The global digital signal controller market continues to grow at a CAGR of over 8% through 2030, driven by expanding industrial automation, EV infrastructure, and renewable energy deployment. The TMS320F28335PGFA is at the heart of this trend.

What Is the TMS320F28335PGFA?

The TMS320F28335PGFA is a 32-bit floating-point Digital Signal Controller (DSC) that bridges the gap between a microcontroller and a DSP. Built on Texas Instruments' C2000 real-time control platform with a C28x core, it combines high-speed DSP computation with MCU-style peripheral integration — enabling engineers to implement advanced closed-loop control algorithms directly in firmware, without a separate DSP chip.

It is widely used in industrial motor drives, servo systems, solar inverters, EV charging stations, UPS systems, and robotics platforms where deterministic sub-microsecond control response is mandatory.

Key Specifications

Why the Hardware FPU Changes Everything

The IEEE 754 single-precision FPU allows the TMS320F28335PGFA to execute complex mathematical transforms — Park and Clarke transformations, PI/PID control loops, SVPWM calculations — in a single clock cycle without the overhead of fixed-point scaling. This eliminates an entire category of development complexity and dramatically shortens firmware development timelines for motor control and power conversion applications.

18 PWM Channels Including 6 High-Resolution HRPWM

The 6 High-Resolution PWM (HRPWM) outputs deliver sub-nanosecond duty-cycle resolution — critical for digital power supplies and multi-level inverters where standard PWM resolution is insufficient for tight voltage and current regulation.

Application Areas

Industrial Motor Drives & Servo Systems

The TMS320F28335PGFA is the de facto standard DSC for field-oriented control (FOC) of AC induction motors and permanent magnet synchronous motors (PMSM). Its 18 PWM channels, dual 12-bit ADC sequencers, and 150 MHz compute speed enable real-time current control loops with update rates exceeding 100 kHz, delivering the dynamic performance required by CNC machine tools, industrial robots, and precision servo amplifiers.

Solar Inverters & Renewable Energy Systems

In grid-tied solar inverters, the TMS320F28335PGFA manages MPPT algorithms, DC-AC conversion, reactive power compensation, and grid synchronization — all simultaneously. Its HRPWM outputs provide the duty-cycle precision required for high-efficiency multilevel topologies, while its CAN and SCI interfaces enable communication with SCADA and energy management systems.

EV Charging Infrastructure

The C2000 platform is widely used in Level 2 and DC fast-charging stations. The TMS320F28335PGFA controls the power factor correction (PFC) stage, DC-DC conversion, battery state estimation, and communication protocols (CAN, Modbus) — handling the complete power conversion chain in a single device.

Uninterruptible Power Supplies (UPS)

High-frequency PWM switching, real-time load monitoring, and fast transient response make the TMS320F28335PGFA ideal for online double-conversion UPS systems protecting data centers, hospitals, and industrial facilities from power disturbances.

Industrial Robotics & Motion Control

Multi-axis coordinated motion requires simultaneous management of multiple encoder feedback loops, PWM outputs, and communication buses. The TMS320F28335PGFA handles all of these in parallel, making it the core processor in high-axis-count servo controllers and collaborative robot joint modules.

Digital Power Supplies

Switching regulators, LLC resonant converters, and telecom rectifiers all benefit from the HRPWM's sub-nanosecond resolution and the fast ADC for voltage/current sensing — enabling tight output regulation even under dynamic load conditions.

Industry Context: C2000 and the Real-Time Control Market

Texas Instruments positions the C2000 family as the industry's leading real-time control platform, with over 10 billion C2000 devices shipped. In 2024 and 2025, TI continues to invest in the C2000 ecosystem through updated software libraries (C2000Ware), hardware design kits, and reference designs for EV charging and industrial drives. While newer C2000 devices such as the TMS320F28379D offer dual-core capability, the TMS320F28335PGFA remains heavily in demand due to its massive installed base, long product lifecycle, and the enormous body of existing firmware built on the C28x architecture.
