FAQ

What is the maximum operating frequency of the TMS320F28034PNT?

The TMS320F28034PNT operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67 ns instruction cycle time. This speed is achieved using the internal PLL with an external crystal or oscillator input on X1/X2 pins, and is fully supported across its specified temperature range (–40°C to 105°C). The TMS320F28034PNT maintains timing integrity under worst-case voltage and temperature conditions per TI's published electrical characteristics.

Does the TMS320F28034PNT include a hardware accelerator for control algorithms?

Yes, the TMS320F28034PNT integrates a programmable Control Law Accelerator (CLA) - a 32-bit floating-point math coprocessor that executes control loops independently of the main C28x CPU. This allows concurrent execution of time-critical tasks such as PID regulators or observers, reducing CPU load and improving system responsiveness without requiring software-based floating-point libraries.

How many PWM channels does the TMS320F28034PNT support, and what resolution is available?

The TMS320F28034PNT supports 12 enhanced PWM (ePWM) channels, each with high-resolution extension (HRPWM) capable of sub-nanosecond timing adjustment. Each ePWM module provides complementary A/B outputs with programmable dead-band, trip-zone protection, and event-triggered ADC start - essential for SiC/GaN gate driver timing in high-frequency power converters.

What analog-to-digital converter specifications does the TMS320F28034PNT provide?

The TMS320F28034PNT features a 12-bit successive-approximation ADC with 16 input channels, 4.6 MSPS maximum sampling rate, and dual sample-and-hold capability. It supports ratio-metric references (VREFHI/VREFLO), operates over the full 0–3.3 V input range, and includes hardware synchronization with ePWM events - enabling precise current/voltage feedback acquisition in real-time power control loops.

Is the TMS320F28034PNT pin-compatible with other devices in the F2803x family?

Yes, the TMS320F28034PNT in the 80-pin LQFP (PN) package shares identical pinout and signal mapping with other PN-suffix F2803x variants including TMS320F28030PNT, TMS320F28031PNT, TMS320F28032PNT, TMS320F28033PNT, and TMS320F28035PNT. This enables hardware reuse across designs with varying memory, PWM, or CLA requirements without PCB redesign.
