Overview
TMS320F28069PZA from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and advanced motor control peripherals including 16-channel ePWM (8 HRPWM-capable), 3 eCAP, 4 HRCAP, 2 eQEP, and 12-bit 3.46-MSPS ADC - deployed in solar inverters, EV charging power modules, and servo drive control.
For engineers reviewing the TMS320F28069PZA datasheet, TMS320F28069PZA pinout, TMS320F28069PZA application, or TMS320F28069PZA equivalent, key selection considerations include its 100-pin LQFP package, single 3.3-V supply operation, 128KB flash/50KB RAM memory map, USB 2.0 device/host support, and AEC-Q100-qualified variants for automotive-grade thermal robustness.
Technical Context
The TMS320F28069PZA implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory model, coupled to a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its VCU extends the instruction set for complex math, CRC, and Viterbi operations.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric reference support, analog comparators with internal 10-bit DACs routed directly to ePWM trip zones, and enhanced HRPWM modules enabling dual-edge modulation for high-frequency digital power control.

FAQ
What is the maximum operating frequency of the TMS320F28069PZA?
The TMS320F28069PZA operates at a maximum CPU frequency of 90 MHz, corresponding to an 11.11-ns instruction cycle time. This frequency is achieved using the internal PLL with either an external crystal (X1/X2) or one of the two on-chip zero-pin oscillators. All timing-critical peripherals - including ePWM, ADC, and CLA - are fully synchronized to this clock domain.
Does the TMS320F28069PZA support USB functionality?
Yes, the TMS320F28069PZA integrates a full-speed USB 2.0 controller supporting both device and host modes. It includes dedicated USB0DP and USB0DM pins, on-chip transceivers, and DMA-accessible endpoints. The USB module supports standard class drivers (CDC, HID, MSC) and is commonly used for firmware updates, debug communication, and host-side data logging in motor control systems.
How many high-resolution PWM channels does the TMS320F28069PZA provide?
The TMS320F28069PZA provides 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel delivers sub-nanosecond duty-cycle resolution using the MEP (Minimum Edge Pulse) technology, enabling precise gate driver timing for SiC/GaN-based power stages in high-frequency digital power converters.
What analog-to-digital converter specifications apply to the TMS320F28069PZA?
The TMS320F28069PZA features a 12-bit ADC with dual sample-and-hold architecture, achieving up to 3.46 million samples per second (MSPS). It supports 16 input channels (ADCINA0–7, ADCINB0–7), ratio-metric referencing (VREFHI/VREFLO), and hardware-triggered simultaneous sampling - critical for three-phase current sensing in motor control applications.
Is the TMS320F28069PZA pin-compatible with other F2806x family members?
Yes, the TMS320F28069PZA in the 100-pin LQFP (PZ) package shares identical pinout and electrical characteristics with other PZ-package F2806x variants including TMS320F28069M and TMS320F28069F. This enables direct hardware reuse across designs targeting different feature sets (e.g., CLA-only vs. InstaSPIN-enabled) without PCB layout changes.
