Ultra-low-power MCU for battery and industrial edge nodes
The STM32L072KZU7 is an ultra-low-power 32-bit MCU built around the ARM Cortex-M0+ core running at 32 MHz. It packs 192 KB of Flash, 20 KB of SRAM, and 6 KB of true EEPROM — enough to run a sensor-fusion algorithm, log calibration data, and hold a real-time operating system without external memory.
Peripherals that save board space and BOM cost
The part integrates a 10-channel 12-bit ADC and two 12-bit DACs, so an external ADC is unnecessary for most analog sensor interfaces. The internal oscillator keeps the crystal off the BOM for non-critical timing.
Package and thermal handling
The 25 I/O count fits compact sensor boards and control modules where every square millimeter counts.
STMicroelectronics lists the STM32L072KZU7 as Active.
