General description
The ultra-low-power STM32L052x6/8 microcontrollers incorporate the connectivity power ofthe universal serial bus (USB 2.0 crystal-less) with the high-performance Arm Cortex-M0+32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), highspeed embedded memories (64 Kbytes of Flash program memory, 2 Kbytes of dataEEPROM and 8 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.The STM32L052x6/8 devices provide high power efficiency for a wide range ofperformance. It is achieved with a large choice of internal and external clock sources, aninternal voltage adaptation and several low-power modes.The STM32L052x6/8 devices offer several analog features, one 12-bit ADC with hardwareoversampling, one DAC, two ultra-low-power comparators, several timers, one low-powertimer (LPTIM), three general-purpose 16-bit timers and one basic timer, one RTC and oneSysTick which can be used as timebases. They also feature two watchdogs, one watchdogwith independent clock and window capability and one window watchdog based on busclock.Moreover, the STM32L052x6/8 devices embed standard and advanced communicationinterfaces: up to two I2C, two SPIs, one I2S, two USARTs, a low-power UART (LPUART),and a crystal-less USB. The devices offer up to 24 capacitive sensing channels to simplyadd touch sensing functionality to any application.
