STM32F301: the cheapest C-M4 in full production!
New STM32F301/302/303 microcontrollers based on the ARM® Cortex®-M4 core with Floating-Point Unit (FPU) are in full production and now in stock at distributors:
STM32F3 devices combine the 72MHz ARM Cortex-M4 core featuring DSP instruction set and FPU with high-performance analog peripherals to bring advanced integration to entry-level mixed-signal control applications.
- STM32F301: The market-first sub-dollar Cortex-M4 devices with FPU in volume production brings 32KBytes to 64KBytes on-chip Flash and 16KByte of SRAM.
- STM32F302 and STM32F303: offer extended Flash density from 32KBytes to 256KBytes. STM32F303 offers higher performance (90DMIPS) thanks to its (CCM-SRAM), which provides a “routine boost” equivalent to >100MHz CPU frequency execution from Flash. Additional STM32F3 devices with up to 512KBytes of Flash will be introduced later this year.
To help engineers try out new ideas and quickly create prototypes, there are:
- The new mbed-compatible STM32F302 Nucleo board, available at $10.32 (NUCLEO-F302R8)
- The existing STM32F303 Discovery kit (STM32F3DISCOVERY)
