STM32F042K4U6 Datasheet PDF - ST Microelectronics

●The STM32F042K4U6 is an entry level STM32 F0 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M0 RISC core operating at a 48MHz frequency, high speed embedded memories (Flash memory up to 16kB and SRAM up to 6KB) and an extensive range of enhanced peripherals and I/Os. This device offer standard communication interfaces (one I²C, one SPI, one I²S, one HDMI CEC and two USARTs), one USB full-speed device (crystal-less), one CAN, one 12-bit ADC, four 16-bit timers, one 32-bit timer and an advanced control PWM timer.
