The 1 KB EEPROM is useful for calibration constants or configuration parameters that need byte-level writes.
The 10-channel 12-bit ADC handles analog sensor inputs directly, reducing external component count.
Housed in a 48-LQFP package (7x7 mm body), it offers 38 I/O lines. The LQFP footprint is widely supported in PCB tools and rework-friendly with a standard hot-air station.
It remains available for new designs and production.
Yes. The Cortex-M0+ core is designed for energy efficiency, the supply range works with common battery chemistries, and the 1.8 V minimum supply reduces power in always-on sensor nodes. The 32 KB Flash and 8 KB SRAM are sized for lightweight IoT protocol stacks and sensor fusion.
The STM32L031C8T6 doubles the Flash to 64 KB and the SRAM to 8 KB (same SRAM). Both share the same 48-LQFP footprint, supply range, temperature grade, and peripheral set. The C8 variant is the choice when firmware size exceeds 32 KB.
The maximum core clock speed is 32 MHz.
