The 16-channel 12-bit ADC and single 12-bit DAC cover most sensor-input and analog-output needs for a control loop or data-acquisition front end. If your design needs more than 51 GPIOs, you'll need to step up to a larger package variant. ## Peripherals and connectivity The internal oscillator means you can skip the external crystal if the timing accuracy requirements are loose, but for USB operation you'll still want a resonator or external clock. ## Package and footprint Housed in a 64-LQFP (10x10 mm) with a 0.5 mm pitch, this is a hand-solderable package if you have a steady hand and a fine tip. The surface-mount footprint is standard for two-layer boards; no hidden thermal pad to worry about. ## Lifecycle and supply ST continues to manufacture the STM32L0 family, and the STM32L053R8T3 remains a current catalog item.","metaTitle":"STM32L053R8T3 STMicro ARM Cortex-M0+ MCU, 32MHz, 64KB Flash","metaDescription":"STM32L053R8T3 32-bit ARM Cortex-M0+ MCU, 32MHz, 64KB Flash, 8KB SRAM, 2KB EEPROM, -40 to 125°C.
