Product details

Memory sizing — the BOM-fit check

128 KB Flash is the mid-range option in the STM32L0 family; it holds a FreeRTOS kernel, a USB stack, and a modest application layer without pushing the link map. The 20 KB SRAM is tight for large frame buffers but adequate for typical sensor fusion and control loops. The 6 KB EEPROM is the real space-saver: it stores device serial numbers, calibration coefficients, and fail-safe parameters without needing a separate memory IC or wasting Flash pages for emulation.

Housed in a 100-pin LQFP (14x14 mm body), this is a hand-solderable and rework-friendly package — no hidden balls, no stencil alignment drama.

ST lists the STM32L083VBT6TR as Active. That means ongoing production, no last-time-buy window to chase, and standard lead times through distribution. For a production BOM this removes the single-source anxiety that haunts NRND or EOL parts. The base product number is STM32L083, so any future die shrinks or package variants will carry the same base code.

Frequently asked questions

What is the difference between STM32L083VBT6 and STM32L083VBT6TR?

The two parts are electrically and mechanically identical. The TR suffix denotes Tape & Reel packaging for automated assembly lines; the non-TR version ships in trays or tubes. There is no difference in silicon, firmware, or operating specifications.

Can STM32L083VBT6TR be used as a replacement for STM32L083VBT6?

Yes, it is a direct drop-in replacement. The only change is the shipping medium — the die, package, pinout, and firmware are identical. A BOM already qualified with the tray version can switch to the TR variant without re-qualification.
