The STM32F334x4/6/8 family incorporates the high-performance Arm ® Cortex ® -M4 32-bit RISC core operating at up to 72 MHz frequency embedding a floating point unit (FPU), high-speed embedded memories (up to 64 Kbytes of Flash memory, up to 12 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The STM32F334x4/6/8 microcontrollers offer 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 32-bit timer, one timer dedicated to motor control, and four general-purpose 16-bit timers. They also feature standard and advanced communication interfaces: one I 2 C, one SPI, up to three USARTs and one CAN. The STM32F334x4/6/8 family operates in the –40 to +85 °C and –40 to +105 °C temperature ranges from 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allow the design of low-power applications. The STM32F334x4/6/8 family offers devices in 32, 48 and 64-pin packages. Depending on the device chosen, different sets of peripherals are included.
