External Memory

In addition to the Flash and RAM internal to the STM32F207IG (or STM32F407IG) MCU, the MCBSTM32F200/400 board contains the following external memory:

  • 2 MB External SRAM located at IC13. Note: If jumpers J10, J11 and J12 are configured for ETM Trace, only 1 MB of this SRAM is accessible.
  • 8 MB External NOR Flash located at IC16. Note: If jumpers J10, J11 and J12 are configured for ETM Trace, only 1 MB of this Flash is accessible.
  • 512 MB External NAND Flash located at IC14 (on the back side of the board).
  • 8 KB EEPROM with NFC (wireless near field communication) interface located at IC15. The NFC antenna is located at L10.
