Product details
Overview
TMS320F28069UPZPS from Texas Instruments is a 90-MHz C28x-based real-time microcontroller with integrated FPU, CLA, and VCU, delivering deterministic control for high-precision motor drives and digital power conversion. It features 128KB flash, 50KB RAM, 16-channel 12-bit ADC (3.46 MSPS), 8 HRPWM channels, eCAN, USB 2.0, and operates from a single 3.3-V supply in –40°C to 125°C industrial temperature range.
For engineers reviewing the TMS320F28069UPZPS datasheet, TMS320F28069UPZPS pinout, TMS320F28069UPZPS application, or TMS320F28069UPZPS equivalent, key selection criteria include its dual-core architecture (C28x + CLA), on-chip analog integration (comparators, DACs, temperature sensor), and support for closed-loop control in solar inverters, servo drives, and EV charging modules.
Technical Context
The TMS320F28069UPZPS implements a Harvard bus architecture with atomic instruction execution and unified memory mapping, enabling efficient C/C++ code deployment. Its CLA executes floating-point math independently of the CPU, offloading time-critical control loops such as field-oriented control (FOC) or PID tuning.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric reference support, three eQEP modules for position feedback, and eight ePWM modules with HRPWM capability for sub-nanosecond timing resolution-critical for SiC/GaN gate drive synchronization and dead-time compensation.

The TMS320F28069UPZPS is rated for –40°C to +125°C (S-grade), making it suitable for industrial environments with elevated ambient temperatures, such as enclosed motor drive cabinets or outdoor solar power conditioning units. This extended range exceeds standard commercial-grade MCUs and ensures reliable operation without forced cooling in many power electronics applications.
Does the TMS320F28069UPZPS include a hardware floating-point unit?
Yes, the TMS320F28069UPZPS integrates a native single-precision floating-point unit (FPU) alongside the C28x CPU core. This enables direct execution of IEEE 754-compliant floating-point arithmetic without software emulation, significantly accelerating mathematical operations used in motor control algorithms, filter design, and system identification routines within the TMS320F28069UPZPS.
How many high-resolution PWM channels does the TMS320F28069UPZPS support?
The TMS320F28069UPZPS supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel provides sub-nanosecond resolution for fine dead-time adjustment and phase-shifted control-essential for minimizing switching losses in SiC and GaN-based power stages used in modern TMS320F28069UPZPS-based designs.
Is USB functionality available on the TMS320F28069UPZPS?
Yes, the TMS320F28069UPZPS includes a full-speed USB 2.0 interface supporting both device and host modes. It integrates a physical layer (PHY) and supports enumeration, HID, CDC, and custom class implementations-enabling direct PC communication for firmware updates, real-time debug streaming, and parameter configuration without external USB-to-UART bridges in the TMS320F28069UPZPS system.
