It carries 64 KB of Flash program memory, 8 KB of SRAM, and 2 KB of embedded EEPROM — enough for a modest sensor-fusion or battery-monitoring firmware image without external storage. The 1.65 V to 3.6 V supply range lets it run directly from two alkaline cells or a single Li-ion, skipping the boost regulator. On-chip peripherals include a 12-bit ADC with 10 channels, a 12-bit DAC, I²C, SPI, UART/USART, USB, and an LCD driver, making it a fit for handheld instruments, IoT edge nodes, and low-power data loggers. ## Industrial temperature range — deployment context 64 KB of Flash and 8 KB of RAM define the firmware ceiling. The 2 KB EEPROM holds calibration constants.","metaTitle":"ST STM32L053C8U6D ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L053C8U6D 32-bit MCU, 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, industrial temp -40°C to 85°C.
