The STM32L0 series is well-established, with broad distribution support. ## Package and footprint — what fits the board The surface-mount package is standard for two-layer boards and reflow profiles. The supplier device package is 64-LQFP (10x10).","metaTitle":"ST STM32L053R8T7 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L053R8T7 32-bit MCU with ARM Cortex-M0+ core, 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, USB, -40°C to 105°C.
