I decided to have a look at the STM32H7x3 series running at 480Mhz. The Nucleo board uses the 144 pin ZI version, but they also have a 100 pin V version. 100 pin is attractive because it gives me access to external memory, Ethernet and more + if I should go for a 100 pin I can as well chose the top-notch – they don’t cost that much more and 1Mb Flash + 1Mb SRAM is convenient.

We all know that Raspberry PI is superior if you want large displays, but I am looking for smaller, embedded displays where I find Raspberry PI to be clumsy due to wiring needs + it’s a few options of interest with this larger MCU.

  • 480 Mhz M7 core
  • double precision FPU
  • Up to 2Mb Flash
  • 1Mb SRAM
  • Fast SPI Memory and external memory
  • 4 x DMA controllers
  • 4 x I2C
  • 8 x USART/UART
  • 6 x SPI up to 150Mhz
  • 4 x SAI
  • 2 x SD/SDIO/MMC
  • 2 x USB
  • Ethernet
  • 22 x Timers
  • 3 x 16 bit ADC’s
  • 2 x 12 bit DAC’s
  • 2 x Op amps
  • 1 x digital filer
  • Graphics accelerator
  • Camera interface
  • And more

 My interest in this is only experimental at the moment.
