STMicroelectronics STM32L052R8Tx
ARM Cortex-M0+, 32 MHz, 64 kB ROM, 8 kB RAM
The STM32L0 devices provides 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. Typical applications include application control and user interfaces, handheld equipment, A/V receivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs - CRC calculation unit, 96-bit unique ID - USB 2.0 crystal-less, battery charging detection and LPM - True RNG and firewall protection
