Detailed Description

High-performance C2000 Delfino real-time control MCU for precision motor control, digital power, and industrial automation. Dual 32-bit C28x CPUs with floating-point and Control Law Accelerator for fast, deterministic control loops. Rich set of PWMs, ADCs, and communication interfaces. Supplied in a 176-pin HTQFP package. Stock available now at Y-IC (approx. 45,101 pcs, subject to prior sale).

Key Features

Dual C28x 32-bit CPUs with hardware floating-point for fast control math

Control Law Accelerator (CLA) for parallel real-time tasks

High-speed operation up to the high hundreds of MHz class for tight loop timing (refer to datasheet for the exact maximum frequency)

Integrated non-volatile flash and on-chip SRAM with ECC

High-resolution PWM (HRPWM), enhanced PWM (ePWM), eCAP, eQEP for precision motor and motion control

Multi-channel high-speed ADC subsystem for sensing current, voltage, position, and feedback signals (check datasheet for resolution and channel count)

Multiple serial interfaces: SPI, I2C, SCI/UART; CAN controllers for robust industrial communications

DMA, watchdog, timers, and event managers for deterministic scheduling

Security and safety features such as code security module and memory ECC/parity

Wide operating temperature range suited for industrial environments

Mature C2000 ecosystem: libraries, motor-control and digital-power SDKs, tools, and reference designs

Key Advantages

Deterministic, low-latency control ideal for FOC motor control and digital power loops

Dual-core + CLA concurrency increases control bandwidth without raising clock speed

Integrated precision PWMs and fast ADCs reduce external components and BOM cost

Strong EMC/EMI performance supported by peripheral design and TI reference layouts

Long lifecycle family with multiple pin-compatible options for easy scaling

Broad developer support and proven field reliability in industrial applications

Packaging

Package type: HTQFP-176 (TI code PTP); shipment option PT indicates Tape and Reel

Body style and size: thin QFP, approximately 24 mm x 24 mm body, 0.5 mm lead pitch (verify exact dimensions in the datasheet)

Pin count and layout: 176 leads including multiple GPIOs, power pins, ADC inputs, PWM outputs, and communication interfaces

Material and finish: Molded epoxy package, lead-free, RoHS-compliant (see TI finish options)

Moisture sensitivity: MSL per TI datasheet and label; observe standard QFP baking/handling practices

Thermal characteristics: Theta-JA/theta-JC values depend on board design and airflow; follow datasheet thermal data and TI layout guidelines; large ground planes and thermal spreading copper recommended

Electrical interface levels: 3.3 V I/O domain; core supplied by internal regulation (refer to datasheet for exact rails, current, and tolerances)

Lifecycle

Current status: In active production per TI’s C2000 family roadmap at the time of the latest public information

Not indicated as near end-of-life; production longevity typical for TI industrial MCUs

Pin-compatible or functionally similar alternatives to consider:

- TMS320F28379D (same family, higher-feature superset in many variants; often pin-compatible in 176-HTQFP)

- TMS320F28377S (single-core variant for cost/power reduction, similar pinout options)

- TMS320F28376D / TMS320F28375D (resource-optimized dual-core options)

- TMS320F2837xD in other packages such as 337-ball BGA (ZWT) when higher I/O density or different thermal profile is preferred

- Next-generation C2000 devices (e.g., F2838x series) for added peripherals like industrial Ethernet/EtherCAT; check migration notes

- Cost-optimized C2000 families (e.g., F28002x/F28003x/F28004x) when single-core and fewer peripherals suffice
