TEXAS INSTRUMENTS TMS320F28335PGFA C2000™ Delfino™ 32-bit MCU
TEXAS INSTRUMENTS TMS320F28335PGFA Product Overview
The TMS320F28335PGFA is a high-performance 32-bit floating-point microcontroller from Texas Instruments' C2000™ Delfino™ series, designed for real-time industrial control applications requiring advanced signal processing and precise analog integration. The device features the C28x core with floating-point unit (FPU) , enabling faster code execution and simplified development compared to fixed-point devices.
Rated for a core supply voltage of 1.9 V (1.805 V to 1.995 V) and I/O supply of 3.3 V, it operates at a maximum system clock of 150 MHz with a cycle time of 6.67 ns. On-chip memory includes 512 KB of flash, 68 KB of SRAM, and 8 KB of boot ROM. The device integrates a 12-bit ADC with 16 channels and 80 ns conversion time, along with up to 18 PWM outputs supporting high-resolution PWM (HRPWM). Operating temperature range is -40°C to +85°C. Housed in a 176-pin LQFP package with surface mount termination. Mass is approximately 1.5 g.

TEXAS INSTRUMENTS TMS320F28335PGFA Key Advantages
The TMS320F28335PGFA employs the C28x core with floating-point unit (FPU) , delivering 150 MHz real-time processing with up to 2x performance improvement over fixed-point devices in common control algorithms such as PID and Kalman filters. The 512 KB on-chip flash and 68 KB SRAM enable code storage and data processing without external memory in many applications.
The 12-bit ADC with dual sample-and-hold and 80 ns conversion time enables simultaneous sampling of current and voltage signals, critical for motor control and power conversion applications. The 6 HRPWM channels with 150 ps resolution provide precise control of power switching devices. The integrated DMA controller enables data movement without CPU intervention, freeing processor bandwidth for control loop execution. The dual CAN modules and extensive serial communication interfaces (SCI, SPI, McBSP, I²C) provide connectivity for industrial networks and peripheral devices.
