Product details

Memory and ADC — sizing for the BOM

256 KB of Flash holds a full motor-control firmware image plus a bootloader and calibration tables; 34 KB of RAM supports three-phase current data arrays, a Modbus buffer, and a real-time trace log. The 12-bit ADC with 16 multiplexed channels samples all three phase currents plus DC-link voltage and temperature in one trigger event — no external mux needed. If your application requires more than 256 KB of code space or 16-bit ADC resolution, this part is not the fit; look at the Delfino or newer Piccolo families.

Texas Instruments has marked the TMS320F28066UPZT as obsolete. No last-time-buy windows remain through the factory channel.

Frequently asked questions

Is TMS320F28066UPZT obsolete?

Yes, Texas Instruments has classified the TMS320F28066UPZT as obsolete. It is no longer available through the factory channel and must be sourced through independent distribution.

What is the replacement for TMS320F28066UPZT?

The closest pin-compatible functional replacement is the TMS320F28067, which shares the same 100-LQFP package, 90 MHz C28x core, and 256 KB Flash. Verify firmware timing compatibility before substituting.

What are the key specifications of TMS320F28066UPZT?

90 MHz C28x core, 256 KB Flash, 34 KB RAM, 54 I/O, 16-channel 12-bit ADC, CAN/USB/SPI/UART, 1.71–1.995 V supply, -40°C to 105°C operating range, 100-LQFP package.
