The STM32L041G6U6STR: 32 MHz ARM Cortex-M0+ core with 32 KB Flash and 10x12-bit ADC.
32 KB Flash, 8K x 8 RAM, 1K x 8 EEPROM.
28-UFQFPN (4x4 mm) package with 23 I/O.
Within the STM32L0 series, pin-compatible alternatives include the STM32L031G6U6 (32 KB Flash, no EEPROM) and the STM32L051G8U6 (64 KB Flash, 2 KB EEPROM). Both share the same 28-UFQFPN footprint and supply voltage range, but differ in memory density and peripheral set. Verify the exact memory and feature requirements before substituting.
The part is lead-free and suitable for lead-free reflow processes.
