The Flash is enough for a field-oriented motor-control stack plus a Modbus RTU or CANopen stack, but leaves little room for a full RTOS with TCP/IP. The 16 KB SRAM handles a couple of 256-point FFT buffers or a modest state-machine scheduler. If your application needs a larger heap or OTA staging area, step up to the STM32F303 series with 48 KB SRAM. ## Package and assembly — 32-LQFP (7x7 mm) The 32-LQFP package with a 7x7 mm body and 0.8 mm pitch is a standard, pick-and-place-friendly footprint. The 25 I/O pins are enough for a sensor hub with a few UART, SPI, and I²C peripherals, but you will run out of pins quickly if you need a parallel LCD or multiple external ADCs.","metaTitle":"ST STM32F301K8T6 ARM Cortex-M4 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F301K8T6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 64 KB Flash, 16 KB SRAM, 25 I/O, 32-LQFP, -40°C to 85°C.

The STM32F301K8T6 supports the standard SWD (Serial Wire Debug) interface used by ST-Link programmers. The SWD pins are available on the 25 I/O lines, and the device boots from internal Flash with BOOT0 strapped low."},{"question":"What is the closest pin-compatible alternative to STM32F301K8T6?","answer":"Within the STM32F3 series, the STM32F303K8T6 is pin-compatible in the same 32-LQFP package but offers 48 KB SRAM and a second 12-bit ADC channel.
