STM32F301K6U6TR — compact Cortex-M4 with 72 MHz and 32 KB Flash
The STMicroelectronics STM32F301K6U6TR is a 32-bit ARM Cortex-M4 microcontroller from the STM32F3 series, clocked at 72 MHz with 32 KB of Flash and 16 KB of SRAM. It packs 24 I/O lines, a 12-bit ADC with 11 channels, a single 12-bit DAC, and connectivity including I2C, SPI, UART/USART, IrDA, and LINbus into a compact package with exposed pad.
At 72 MHz the Cortex-M4 delivers single-cycle multiply-accumulate and hardware divide. The FPU handles float math without software emulation.
