Product details
Overview
TMS320F28069PZA from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and 12-bit 3.46-MSPS ADC, designed for closed-loop motor control and digital power conversion. It delivers 16 ePWM channels (8 HRPWM-capable), 3 eCAP modules, 4 HRCAP modules, dual-sample-and-hold ADC, and on-chip temperature sensor - deployed in solar inverters, EV charging stations, and servo drive control modules.
For engineers reviewing the TMS320F28069PZA datasheet, TMS320F28069PZA pinout, TMS320F28069PZA application, or TMS320F28069PZA equivalent, key selection criteria include CLA-accelerated floating-point control loop execution, dual-edge HRPWM timing resolution, 54 GPIO with input filtering, USB 2.0 device/host support, and 128KB flash/50KB RAM memory configuration.
Technical Context
The TMS320F28069PZA implements a Harvard-architecture C28x CPU with atomic instruction support and unified memory programming model, enabling deterministic real-time interrupt response. Its dedicated CLA executes floating-point math independently of the main CPU, offloading PID and field-oriented control (FOC) computations.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references, analog comparators routed directly to ePWM trip zones, and enhanced ePWM modules supporting dual-edge modulation. The device uses internal voltage regulation for single 3.3-V rail operation and features two zero-pin oscillators plus PLL-based clock synthesis.

Does the TMS320F28069PZA support USB functionality?
Yes, the TMS320F28069PZA integrates a full-speed USB 2.0 PHY supporting both device and host modes at 12 Mbps. It requires no external transceiver and connects directly via USB0DP/USB0DM pins - confirmed in the Device Comparison table and Section 3.2 System Device Diagram of the official datasheet.
How many high-resolution PWM channels does the TMS320F28069PZA provide?
The TMS320F28069PZA provides 8 high-resolution PWM (HRPWM) channels, all derived from its 8 ePWM modules. Each HRPWM channel supports dual-edge control with sub-nanosecond timing resolution, enabling precise dead-time insertion and phase-shift modulation in resonant converters - specified in Section 1 Features and Table 5-1.
What ADC performance specifications apply to the TMS320F28069PZA?
The TMS320F28069PZA features a 12-bit analog-to-digital converter with dual sample-and-hold architecture, achieving up to 3.46 million samples per second (MSPS) and 289-ns conversion time.
