STM32F334R8T7

STM32F334R8T7 is a STM32 F3 series, mainstream mixed signals microcontroller (MCU) from the STM32F303 family. It incorporates the high-performance Arm® Cortex®-M4 32-bit RISC core operating at up to 72MHz frequency embedding a floating point unit (FPU), high-speed embedded memories and an extensive range of enhanced I/Os and peripherals connected to dual APB buses. This MCU offers two fast 12-bit ADCs, up to three ultra-fast comparators, an operational amplifier, three DAC channels, a low-power RTC, one high-resolution timer, one general-purpose 32-bit timer, one timer dedicated to motor control, and four general-purpose 16-bit timers, 26 normal I/Os (TC, TTa), 25 5V tolerant I/Os (FT,FTf), 18 capacitive sensing channels. It also features standard and advanced communication interfaces: one I2C, one SPI, up to three USARTs and one CAN.
