Description

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 I2C, 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 a 2.0 to 3.6 V power supply. A comprehensive set of power-saving

modes allows 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.
