It runs at 32 MHz and packs 192 KB of Flash program memory, 20 KB of SRAM, and a rare on-chip 6 KB EEPROM that eliminates the external serial EEPROM for parameter storage.
192 KB Flash and 6 KB EEPROM — memory budget for field-upgradable firmware
The 20 KB SRAM handles moderate-sized data arrays and communication buffers; if your design needs larger frame buffers for graphics on the segment LCD controller (listed in peripherals), budget the RAM carefully. The 6 KB EEPROM is the standout feature — it stores calibration constants, configuration profiles, and security keys without wearing the Flash, and it survives 100k write cycles typical of the STM32L0 family. That saves a 1-cent external EEPROM and one I²C bus slot on the BOM.
The supplier device package is 64-LQFP (10x10), so the footprint matches the common 64-pin LQFP land pattern.
The STM32L0 series is a mature, broadly deployed family, so independent-channel availability is reliable.
