STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability: - bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each) - bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each) While other STM32F10x devices features only one bank with memory up to 512 Kbytes. In version V3.3.0, some functions were updated and new ones were added to support STM32F10x_XL devices. Thus some functions manages all devices, while other are dedicated for XL devices only. The table below presents the list of available functions depending on the used STM32F10x devices. *************************************************** * Legacy functions used for all STM32F10x devices * *************************************************** +----------------------------------------------------------------------------------------------------------------------------------+ | Functions prototypes |STM32F10x_XL|Other STM32F10x| Comments | | | devices | devices | | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_SetLatency | Yes | Yes | No change | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_HalfCycleAccessCmd | Yes | Yes | No change | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_PrefetchBufferCmd | Yes | Yes | No change | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_Unlock | Yes | Yes | - For STM32F10X_XL devices: unlock Bank1 and Bank2. | | | | | - For other devices: unlock Bank1 and it is equivalent | | | | | to FLASH_UnlockBank1 function. | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_Lock | Yes | Yes | - For STM32F10X_XL devices: lock Bank1 and Bank2. | | | | | - For other devices: lock Bank1 and it is equivalent | | | | | to FLASH_LockBank1 function. | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_ErasePage | Yes | Yes | - For STM32F10x_XL devices: erase a page in Bank1 and Bank2 | | | | | - For other devices: erase a page in Bank1 | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_EraseAllPages | Yes | Yes | - For STM32F10x_XL devices: erase all pages in Bank1 and Bank2 | | | | | - For other devices: erase all pages in Bank1 | |----------------------------------------------------------------------------------------------------------------------------------| |FLASH_EraseOptionBytes | Yes | Yes | No change | |--------------------------------------------------------------------
