TMS320F28034PNT - 60MHz C2000 Piccolo MCU | Texas Instruments
MPN: TMS320F28034PNT ✓ نشطTMS320F28034PNT نظرة عامة
A microcontroller (MCU) is a compact integrated circuit that combines a processor core, memory, and programmable input/output peripherals on a single chip. The C28x core is a 32-bit fixed-point DSP optimized for real-time control, offering high-speed math capabilities essential for closed-loop systems. The TMS320F28034PNT belongs to the C2000 family, which is specifically designed for applications requiring precise, deterministic control.
Key features include a 60 MHz C28x CPU, 128 KB flash, 20 KB RAM, a 12-bit ADC with up to 16 channels, and multiple communication interfaces such as SPI, SCI (UART), I2C, and CAN. The device also includes ePWM modules, eQEP, eCAP, and a watchdog timer. The Control Law Accelerator (CLA) is a co-processor that can execute control algorithms independently, freeing the main CPU for other tasks.
The TMS320F28034PNT operates from a 3.3V I/O supply with an internal 1.8V core, and supports a temperature range of -40°C to 105°C. It is code-compatible with other C28x devices, allowing software reuse across the family. The device is available in a lead-free, RoHS-compliant LQFP-80 package.
Typical applications include field-oriented control (FOC) of AC induction and BLDC motors, digital power supplies (e.g., LLC converters), solar inverters, and industrial drives. The high-performance ADC and PWM modules make it ideal for precise current and voltage sensing and control.
When designing with this MCU, ensure proper decoupling of the 3.3V and 1.8V supplies, and consider using the internal voltage regulator with external capacitors as specified in the datasheet. The JTAG interface is essential for debugging and programming, and should be routed with appropriate signal integrity.

ملاحظات التصميم
The TMS320F28034PNT requires a 3.3V I/O supply and a 1.8V core supply. The core supply can be generated internally using the on-chip voltage regulator, but external capacitors are required as specified in the datasheet. Ensure proper decoupling with 100nF and 10uF capacitors close to the VDD and VDDIO pins to minimize noise and voltage transients.
For the LQFP-80 package, ensure adequate thermal relief and grounding. The exposed pad (if present) should be soldered to a large copper area for heat dissipation. Route JTAG signals with controlled impedance and keep them short to avoid signal integrity issues. Place the crystal oscillator close to the X1/X2 pins with proper load capacitors.
A common mistake is neglecting the internal voltage regulator's capacitor requirements, leading to unstable core voltage. Also, ensure the ADC reference pins (VREFHI/VREFLO) are properly bypassed with capacitors to achieve accurate conversions. Avoid exceeding the absolute maximum ratings on any pin, especially during programming.
