The STM32L052R8T6 is an ultra-low-power STM32 L0 series 32-bit Microcontroller incorporates the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance ARM Cortex-M0+ RISC core operating at a 32MHz frequency. It features a memory protection unit (MPU), high-speed embedded memories (64kB of Flash program memory, 2kB of data EEPROM and 8kB of RAM) plus an extensive range of enhanced I/Os and peripherals. This device provide high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation and several low-power modes.

- Ultra-safe, low-power BOR (brownout reset) with 5 selectable thresholds
- Ultralow-power POR/PDR
- Programmable voltage detector (PVD)
- 1 to 25MHz Crystal oscillator
- 32kHz Oscillator for RTC with calibration
- High-speed internal 16MHz factory-trimmed RC (±1%)
- Internal low-power 37kHz RC
- Internal multispeed low-power 65kHz to 4.2MHz RC
- Internal self calibration of 48MHz RC for USB
- PLL for CPU clock
