TMS320F28034PNT - 60MHz C2000 Piccolo MCU, 128KB Flash | TI
The Texas Instruments TMS320F28034PNT is a 32-bit C28x microcontroller from the C2000 Piccolo family, running at 60 MHz with 128 KB of on-chip flash and 20 KB of SRAM, housed in an 80-pin LQFP (12x12 mm) package. It targets real-time control applications such as industrial motor drives, digital power conversion, solar inverters, and switched-mode power supplies, integrating a Control Law Accelerator (CLA) co-processor for offloading deterministic control loops from the main CPU. Per the TI product page, the device is part of the C2000 line optimized for processing, sensing, and actuation to improve closed-loop performance.
A microcontroller (MCU) is a compact integrated circuit that combines a processor core, volatile and non-volatile memory, and programmable peripherals on a single die. The C28x core is a 32-bit fixed-point DSP-style architecture tuned for deterministic, low-latency math on real-time control loops. Within TI's portfolio the C2000 Piccolo series sits below the Premium-performance Delfino MCUs and above the C2000 Entry-performance line, all sharing the C28x ISA for code portability across motor control, digital power, and sensing designs.
Key features include a 60 MHz C28x CPU, 128 KB single-bank flash with 64K x 16 organization, 20 KB RAM, a 12-bit ADC with up to 16 input channels and a 0 to 3.3 V fixed full-scale range that supports ratio-metric VREFHI/VREFLO references, plus ePWM, eQEP, eCAP, SPI, SCI (UART), I2C, and CAN interfaces. Analog comparators with internal 10-bit references can be routed directly to the PWM outputs for fast overcurrent/overvoltage protection, while the ADC interface has been optimized for low overhead and latency.
The architecture combines a C28x main CPU with the CLA co-processor, enabling parallel execution of closed-loop math such as field-oriented control (FOC) state calculations. The on-chip voltage regulator produces the internal 1.8 V core from an external 3.3 V supply, simplifying board design but requiring the bypass network specified in the datasheet.
Typical applications include FOC for AC induction motors and BLDC motors, LLC and PFC stages of telecom and server power supplies, solar micro-inverters, and industrial servo drives. The combination of high-resolution PWM, fast ADC, and CLA makes this MCU a strong fit for digital control loops running at tens of kilohertz.
A key design tip: place the 1.8 V regulator bulk and bypass capacitors exactly as shown in the datasheet reference design, since the internal LDO powers the core and any ripple will translate into reduced ADC performance and noise on the PWM edge timing.
This page synthesizes TI datasheet parameters, drop-in alternatives within the LQFP-80 footprint, and practical design notes beyond what the manufacturer datasheet provides, helping engineers quickly validate the part for their real-time control application.
