It carries 8K x 8 of SRAM and a separate 2K x 8 EEPROM block for non-volatile parameter storage, running from a 1.65 V to 3.6 V supply. The part is housed in a 48-LQFP package with 37 I/O, includes a 10-channel 12-bit ADC, and is specified over the -40°C to 105°C industrial temperature range. Typical applications include battery-powered sensors, industrial control nodes, metering, and IoT edge devices where low power draw and a wide supply range are critical. ## End-of-life status — sourcing reality for this STM32L051C8T7TR This order code is flagged end-of-life (EOL) in the distribution channel. While the manufacturer's product status shows Active, the hot-stage EOL indicator means last-time-buy windows may be closing for some supply routes. For new BOM entries or long-production-run designs, a pin-compatible alternative within the STM32L0 family should be evaluated for continuity.","metaTitle":"ST STM32L051C8T7TR ARM Cortex-M0+ MCU, 32MHz, 64KB Flash","metaDescription":"STMicroelectronics STM32L051C8T7TR: 32-bit ARM Cortex-M0+ MCU at 32MHz, 64KB Flash, 8K x 8 RAM, 2K x 8 EEPROM, 48-LQFP, -40 to 105°C.
