Product details

Ultra-low-power Cortex-M0+ with on-chip LCD and EEPROM

The STM32L083CZT6 provides 192 KB of Flash, 20 KB of SRAM, and 6 KB of hardware EEPROM.

192 KB Flash and 6 KB EEPROM — memory budget for code and calibration data

The 192 KB Flash (192K x 8) is sized for a full application stack — RTOS, USB stack, LCD driver, and sensor fusion algorithms — with room left for a small OTA staging buffer. The 6 KB EEPROM is a hardware EEPROM array, not a Flash-emulation trick, so you can write individual bytes without block-erase cycles. That matters for designs that store calibration constants, serial numbers, or configuration parameters that change infrequently over a 10-year product life.

No extended-temperature variant is needed for most industrial sensor nodes.

Active lifecycle — no supply risk for new production

STMicroelectronics lists the STM32L083CZT6 as Active.

Frequently asked questions

Does STM32L083CZT6 support USB and LCD simultaneously?

Yes. The STM32L083CZT6 includes both a USB 2.0 FS interface (with integrated PHY) and a segment LCD driver as on-chip peripherals. The two can operate concurrently, subject to pin multiplexing — the 48-LQFP package provides 40 I/O lines, so the system architect should verify that the required LCD segment count and USB D+/D− pins do not conflict with other I/O needs.

How does STM32L083CZT6 compare to STM32L073CZT6?

The STM32L073CZT6 is a pin-compatible alternative in the same 48-LQFP package. The key difference is that the L083 includes a 6 KB hardware EEPROM and a segment LCD driver, while the L073 omits both. If your design does not need the LCD controller or dedicated EEPROM, the L073 is a cost-optimized second source. Both share the same Cortex-M0+ core, 192 KB Flash, 20 KB RAM, and peripheral set otherwise.
