The STM32F301K6T6: 32 KB Flash and 16K x 8 SRAM, 25 I/O, and peripherals including DMA, I²S, POR, PWM, WDT.
32 KB Flash (32K x 8) and 16K x 8 SRAM. On-chip data converters: 8-channel 12-bit ADC and one 12-bit DAC.
The STM32F301K6T6 is rated for a maximum operating speed of 72 MHz. At this frequency the flash wait state must be set to 1 before raising the core clock, or the part will hard-fault on the first branch instruction.
A functional alternative in the STM32 portfolio is the STM32L151CBU6A, which runs a Cortex-M3 core at 32 MHz with 37 I/O and USB connectivity. The trade-off is a lower clock speed and different peripheral mix — the series targets ultra-low-power operation, not the signal-processing throughput of the F3's Cortex-M4 at 72 MHz.
