STM32L083CZT6TR packs 192 KB of Flash, 20 KB of SRAM, and 6 KB of embedded EEPROM, saving an external EEPROM chip on the BOM for parameter storage or calibration data.
With 40 I/O lines in a 48-LQFP package (7x7 mm), it provides enough pins for sensor aggregation, small displays, and control loops without needing a larger package.
The only difference is the packaging format: STM32L083CZT6TR is supplied in Tape & Reel (TR) for automated pick-and-place assembly, while the STM32L083CZT6 typically ships in trays or tubes. The silicon, package, and specifications are identical.
Yes, the TR suffix explicitly indicates Tape & Reel packaging, suitable for high-volume SMT assembly lines.
The core is rated for a maximum clock speed of 32 MHz.
