On-chip memory includes 128 KB of Flash for program storage, 20 KB of SRAM for data and stack, and a separate 6 KB EEPROM block — the dedicated EEPROM means you can store calibration constants or configuration parameters without wearing out the Flash, which is a common pain point on cheaper MCUs that emulate EEPROM in Flash. ## Peripherals and I/O — enough to talk to the outside world The built-in brown-out detect and POR eliminate the need for a separate supervisor IC in most designs.","metaTitle":"STM32L081CBT6 MCU, ARM Cortex-M0+, 32 MHz, 128KB Flash","metaDescription":"Active STM32L0 MCU: 32 MHz Cortex-M0+, 128KB Flash, 20K RAM, 6K EEPROM, 1.65V–3.6V, -40°C to 85°C, 48-LQFP.
