The 2 KB EEPROM saves an external serial EEPROM for calibration constants or configuration data that must survive a reset. Peripherals include brown-out detect, reset, DMA, I²S, PWM, watchdog timers, and a 12-bit ADC with 16 channels plus a 12-bit DAC. With 51 general-purpose I/O lines in the 64-TFBGA package, most designs will have spare pins for expansion or diagnostics. ## Package and storage note for the 64-TFBGA Store the reels dry — MSL 3 out of the bag means bake before reflow if the moisture-barrier bag has been open past the floor-life window.","metaTitle":"STM32L053R6H6 ARM Cortex-M0+ MCU, 32KB Flash, 8KB RAM, 32MHz","metaDescription":"STMicroelectronics STM32L053R6H6 32-bit ARM Cortex-M0+ MCU, 32KB Flash, 8KB RAM, 32MHz, 64-TFBGA.
