TI TMS320F28069PZT C2000 Real-Time Microcontroller

The TMS320F28069PZT is a 32-bit C2000 real-time microcontroller from Texas Instruments built for closed-loop control: motor drives, solar inverters, digital power supplies and UPS control boards. A 90 MHz C28x core with a single-precision floating-point unit is paired with a programmable Control Law Accelerator (CLA), so current and voltage loops can run independently of the main CPU. The PZT suffix identifies the 100-pin LQFP package in the T temperature grade.

Technical specifications

Reading the part number before you order

The F2806x datasheet covers the whole family, so the suffix matters. PZ is the 100-pin LQFP, while PZP is the 100-pin PowerPAD HTQFP and PN and PFP are the 80-pin packages; the footprints are not interchangeable. The final letter sets the grade: T is -40 to 105 degC junction, S is -40 to 125 degC, and Q is the automotive-qualified option. Variants such as the F28069F (InstaSPIN-FOC enabled), the F28069M (InstaSPIN-MOTION enabled, which TI no longer recommends for new designs) and the F28069U are different orderable parts, so match the full marking on the original chip, not just the number 28069. The datasheet notes that USB is present on the U, M and F versions, and TI names the F28004x series as the roadmap option for users of the F2806x.

Where the F28069 is used

Texas Instruments lists AC drive control modules, servo drive control, string inverters, three-phase UPS, EV charging power modules, welding machines, CNC control and air-conditioner outdoor units among its target uses. In practice it is a frequent control chip on inverter, drive and UPS boards that are repaired or replaced in service. For a pure floating-point control job with a larger package and more memory, compare it with the TI TMS320F28335PGFA digital signal controller, and see other parts in controllers and data acquisition.

Documents and quotation

The linked document is the Texas Instruments F2806x real-time microcontrollers datasheet (SPRS698J). Before ordering, confirm the full orderable part number, package, temperature grade and date code against the board being repaired, and note that a replacement chip arrives blank and needs the application firmware to be programmed through JTAG. Because the 28069 sits in a multi-device datasheet, the table above gives the figures that apply to the full-featured 28069 variants; the electrical limits, pin multiplexing and timing tables remain in the document.
