Texas Instruments TMS320F28069UPZT

Overview

TMS320F28069UPZT 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, digital power conversion, and industrial actuation. It features 128KB flash, 50KB RAM, 8 ePWM modules (16 channels, 8 HRPWM-capable), 3 eCAP, 4 HRCAP, 2 eQEP, USB 2.0, eCAN, and 54 GPIOs - deployed in solar inverters, EV charging stations, and servo drives.

For engineers reviewing the TMS320F28069UPZT datasheet, TMS320F28069UPZT pinout, TMS320F28069UPZT application, or TMS320F28069UPZT equivalent, key selection criteria include HRPWM dual-edge modulation capability, on-chip CLA for independent floating-point control law execution, 12-bit ADC latency of 289 ns, VCU-accelerated CRC/Viterbi operations, and PowerPAD™ HTQFP-100 thermal performance in high-power density systems.

Technical Context

The TMS320F28069UPZT implements a Harvard bus architecture with atomic instruction execution and unified memory mapping, enabling deterministic real-time response. Its C28x CPU runs at 90 MHz (11.11-ns cycle time) and supports 16×16/32×32 MAC operations plus dual 16×16 MAC for motor control algorithms.

Control loop acceleration is achieved via a dedicated 32-bit floating-point CLA core that executes independently of the main CPU, while the Viterbi/Complex Math/CRC Unit (VCU) extends the instruction set for signal integrity and error detection in power electronics firmware.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28069UPZT?

The TMS320F28069UPZT operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This timing is confirmed in the device comparison table and supported by the on-chip PLL and dual zero-pin oscillators, enabling deterministic execution of control loops with sub-microsecond jitter in real-time applications such as motor phase current regulation.

Does the TMS320F28069UPZT include a floating-point unit and programmable control law accelerator?

Yes, the TMS320F28069UPZT integrates both a native single-precision floating-point unit (FPU) and a programmable control law accelerator (CLA). The CLA is a 32-bit floating-point co-processor that executes independently of the main C28x CPU, allowing parallel execution of time-critical control algorithms - a feature explicitly documented in the "Features" section and functional block diagram of the TMS320F28069UPZT datasheet.

What ADC specifications does the TMS320F28069UPZT support?

The TMS320F28069UPZT features a 12-bit analog-to-digital converter with dual sample-and-hold, capable of 3.46 million samples per second (MSPS) and a fixed 289-ns conversion time. It supports up to 16 input channels with ratio-metric VREFHI/VREFLO references, and its design enables simultaneous sampling across two banks - all confirmed in the "Features" and "Device Comparison" tables of the official datasheet.

Which communication interfaces are integrated into the TMS320F28069UPZT?

The TMS320F28069UPZT integrates two SCI/UART modules, two SPI modules, one I²C bus, one McBSP bus, one eCAN module, and one USB 2.0 interface supporting full-speed device and host modes. These peripherals are listed under "Serial port peripherals" in the datasheet features and verified in the device comparison table, with USB functionality confirmed for the "U" variant (TMS320F28069U).

What package type and thermal characteristics apply to the TMS320F28069UPZT?

The TMS320F28069UPZT uses a 100-pin PowerPAD™ HTQFP (PZP) package measuring 14.0 mm × 14.0 mm with an exposed thermal pad. As specified in the "Mechanical, Packaging, and Orderable Information" section, the PowerPAD must be soldered to the PCB ground plane to achieve optimal thermal conduction - delivering 2.8°C/W junction-to-board resistance for reliable operation at 1.2W dissipation.
