The STM32F334K8U6 is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at a maximum frequency of 72 MHz. It features up to 64 KB of Flash memory and 12 KB of SRAM, with an additional 4 KB of SRAM for critical code and data. The device supports a wide voltage range from 2.0 to 3.6 V and includes various low-power modes for energy efficiency. This microcontroller is equipped with two 12-bit ADCs capable of handling up to 21 channels, as well as three 12-bit DACs. It also includes multiple timers, including a high-resolution timer (HRTIM) with 10 PWM outputs and various fault inputs. Communication interfaces include CAN, SPI, and up to three USARTs, making it suitable for a range of applications. The STM32F334K8U6 supports advanced features such as capacitive sensing channels, ultra-fast rail-to-rail analog comparators, and an operational amplifier that can be configured in programmable gain amplifier mode. It is available in multiple package options, including a compact 32-UFQFPN (5x5 mm) package, making it suitable for space-constrained designs.
