Product details

STM32L083CBT6 — ultra-low-power Cortex-M0+ with integrated LCD and EEPROM

The STMicroelectronics STM32L083CBT6 is a 32-bit ARM Cortex-M0+ MCU from the STM32L0 series, built for battery-powered and energy-harvesting applications. It runs at 32 MHz and packs 128 KB of Flash program memory, 20 KB of SRAM, and a separate 6 KB EEPROM block for parameter storage without external parts. The wide 1.8 V to 3.6 V supply range lets it run directly from two alkaline cells or a single Li-ion cell, and the industrial temperature grade (-40°C to 85°C) covers outdoor sensor nodes, metering, and industrial control panels.

What the memory and peripherals mean for your BOM

The 128 KB Flash and 6 KB EEPROM store firmware and configuration data. The 20 KB SRAM supports moderate buffering.

Frequently asked questions

What is the difference between STM32L083CBT6 and STM32L083C8T6?

The STM32L083C8T6 has 64 KB of Flash and 10 KB of RAM, while the STM32L083CBT6 doubles those to 128 KB Flash and 20 KB RAM. Both share the same 48-LQFP package, pinout, and peripheral set.

What is the difference between STM32L083CBT6 and STM32L073CBT6?

The STM32L073CBT6 lacks the integrated LCD driver and the separate EEPROM block that the STM32L083CBT6 includes. Both have 128 KB Flash and 20 KB RAM, but the L073 uses a different memory map and peripheral set.

Can STM32L083CBT6 run on batteries?

Yes. The 1.8 V to 3.6 V supply range allows direct operation from two alkaline cells, a single Li-ion cell, or a LiFePO4 cell without an external regulator. The ultra-low-power architecture draws under 100 µA in sleep mode with LCD retention.

What is the datasheet for STM32L083CBT6?

The full datasheet and reference manual are available from STMicroelectronics. The base product number is STM32L083; the document covers the entire STM32L083xx family including this variant.
