STM32F334R8T7

The STM32F334R8T7 is a STM32 F3 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M4 RISC core operating at a frequency of up to 72MHz and embedding a floating point unit (FPU), high-speed embedded memories (Flash memory up to 64kB and 16kB of SRAM) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The device offer a fast 12-bit ADCs, three comparators, an operational amplifier, three DAC channels, four general-purpose 16-bit timers, one general-purpose 32-bit timer, as well as standard and advanced communication interfaces - one I²C, one SPI, three USARTs and a CAN.
