Product details

What the STM32L083RZT6 brings to the BOM

The STM32L083RZT6 is an STMicroelectronics ultra-low-power 32-bit MCU built around the ARM Cortex-M0+ core, running at 32 MHz. It packs 192 KB of Flash, 20 KB of SRAM, and 6 KB of true EEPROM on-chip — enough for a sensor-fusion algorithm, a USB stack, and a small file system without external memory. With 51 GPIOs in the 64-LQFP package, it fits control panels and human-machine interfaces that need a moderate pin count.

Memory that simplifies the layout

The 6 KB EEPROM is a standout for production firmware: you can store calibration constants, serial numbers, or configuration data without an external I²C EEPROM. The 192 KB Flash and 20 KB RAM are sized for a FreeRTOS project with a USB CDC class and a modest display buffer. No external memory bus is needed, which keeps the PCB two-layer friendly.

Connectivity and peripherals for sensor hubs

The LCD controller drives a segment LCD directly, which saves a separate driver IC in metering or thermostat designs.
