STM32L052K8T7

The STM32L052K8T7 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.

• 0.95 DMIPS/MHz
• 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
