Product details

32 MHz Cortex-M0+ with 192 KB Flash — the ultra-low-power baseline

The STM32L082CZU6 is an STMicroelectronics ultra-low-power 32-bit MCU built around the ARM Cortex-M0+ core running at 32 MHz. It carries 192 KB of Flash program memory, 20 KB of SRAM, and an integrated 6 KB EEPROM — enough for moderate firmware stacks and persistent parameter storage without an external serial EEPROM.

Peripherals and connectivity for sensor-node and human-interface designs

Connectivity covers I²C, IrDA, LINbus, SPI, UART/USART, and USB — enough for a sensor hub, a simple HMI with segment LCD, or a USB-to-serial bridge. The 40 GPIOs in the 48-UFQFN package give reasonable headroom for parallel interfaces and button/LED matrices.

The device integrates a 13-channel 12-bit ADC and two 12-bit DACs, sufficient for reading analog sensors (temperature, pressure, battery voltage) and generating control voltages or audio waveforms.

Package and thermal management — 48-UFQFN with exposed pad

The exposed pad also provides a low-inductance ground return — critical for the USB interface's signal integrity.

STMicroelectronics lists the STM32L082CZU6 as an active product (current lifecycle stage). The base product number STM32L082 covers a family of Flash and package options; this specific variant (CZU6) is the 48-UFQFN, -40 to 85°C grade.

Frequently asked questions

What is the maximum clock frequency of STM32L082CZU6?

The core runs at 32 MHz maximum. At this speed the Flash requires zero wait states for single-cycle access; the Cortex-M0+ pipeline keeps most instructions at one cycle.

What is the closest pin-compatible alternative to STM32L082CZU6 in the STM32L0 family?

Within the STM32L0 series, the STM32L081CZU6 and STM32L083CZU6 share the same 48-UFQFN footprint and pinout. The L081 drops the LCD driver and EEPROM; the L083 adds a second ADC and more LCD segments. Verify the peripheral set against your firmware requirements before substituting.
