STM32F334K8U6

STM32F334K8U6 is a high-performance Arm® Cortex®-M4 32bit 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 two APB buses. This microcontroller offers two fast 12-bit ADCs (5 Msps), up to three ultra-fast comparators, an operational amplifier, three DAC channels, a low-power RTC, one high-resolution timer, one general-purpose 32bit timer, one timer dedicated to motor control, and four general-purpose 16-bit timers. They also feature standard and advanced communication interfaces: one I2C, one SPI, up to three USARTs and one CAN.
