STM32F334R8T6 LQFP-64 microcontroller ST original stock

describe
The STM32F334x4/6/8 series includes high-performance ARM ® cortex ®- The M4 32-bit RISC core operates with floating point units (FPUs) embedded at 72 MHz, high-speed embedded memory (64K bytes of flash memory, 12K bytes of SRAM), and a wide range of enhanced i/operations and peripherals connected to two APB buses.
The STM32F334x4/6/8 microcontroller provides two fast 12-bit ADCs (5Msps), up to three ultra fast comparators, an operational amplifier, three DAC channels, a low-power RTC, a high-resolution timer, a general-purpose 32-bit timer, a timer specifically designed for motor control, and four general-purpose 16-bit timers. They also have standard and advanced communication interfaces: one I2C, one SPI, up to three usarts, and one CAN.

The STM32F334x4/6/8 series uses a power supply of -40 to+85 ° C and -40 to+105 ° C, with a temperature range of 2.0 to 3.6 V. A comprehensive energy-saving mode allows for the design of low-power applications.

The STM32F334x4/6/8 series offers devices in 32, 48, and 64 pin packages.

Depending on the selected device, different sets of peripherals are also included.
