STM32F050K4U6A

Description

The STM32F050xx family incorporates the high-performance ARM Cortex™-M0 32-bit RISC core operating at a 48 MHz maximum frequency, high-speed embedded memories (Flash memory up to 32 Kbytes and SRAM up to 4 Kbytes), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (one I2C, one SPI, one I2S, and one USART), one 12-bit ADC, up to five general-purpose 16-bit timers, a 32-bit timer and an advanced-control PWM timer.
