Product details

Memory and peripherals — what fits in 32 KB

The 1 KB EEPROM is a genuine hardware EEPROM, not emulated Flash, so you can store calibration constants or configuration bytes without wearing out a Flash sector.

Temperature range and environment

The 48-UFQFPN package with exposed pad helps pull heat out when the core is running flat-out at 32 MHz, though in practice most designs will clock down to save power.

Lifecycle and supply position

For BOM planning that is one less headache — no need to qualify a drop-in replacement or stockpile for an EOL notice.

Frequently asked questions

What is the closest pin-compatible alternative to STM32L041C6U6?

Within the STM32L0 series, pin-compatible alternatives exist with different Flash/RAM densities — for example, the STM32L031 and STM32L051 families share the same 48-pin UFQFPN footprint. The exact memory and peripheral set varies, so check the specific part's datasheet for peripheral compatibility before substituting.
