31 / 71 page ![]() DocID023072 Rev 3 31/71 AN4088 Peripheral migration 70 Table 17. Flash differences between STM32F1 series and STM32F0 series(1) FLASH STM32F1 series STM32F0 series Main/Program memory Start Address 0x0800 0000 0x0800 0000 End Address up to 0x080F FFFF up to 0x0803 FFFF Granularity Page of 2 Kbytes size except for Low and Medium density Page of 1 Kbytes up to 32 Sector of 4 Kbytes: sector is 4 Pages of 1 Kbytes on STM32F03x, STM32F04x and STM32F05x or 2pages of 2Kbytes on STM32F07x. The STM32F09x has 31 sectors of 4 Kbytes and 1 sector of 132 Kbytes. EEPROM memory Start Address Available by SW emulation Available by software emulation End Address System memory Start Address 0x1FFF F000 0x1FFF EC00 on STM32F03/5x 0x1FFF C800 on STM32F07x 0x1FFF C400 on STM32F04x 0x1FFF D800 on STM32F09x End Address 0x1FFF F7FF 0x1FFF F7FF Option Bytes Start Address 0x1FFF F800 0x1FFF F800 End Address 0x1FFF F80F 0x1FFF F80B on STM32F03x, STM32F04x and STM32F05x 0x1FFF F80F on STM32F07x and STM32F09x Flash interface Start address 0x4002 2000 0x4002 2000 Programming procedure Same for all product lines Same as STM32F1 series for Flash program and erase operations. Different from STM32F1 series for Option byte programming(2) Read Protection Unprotection Read protection disable RDP = 0xA55A Level 0 no protection RDP = 0xAA Protection Read protection enable RDP != 0xA55A Level 1 memory protection RDP != (Level 2 & Level 0) Level 2: Lvl 1 +Debug disabled RDP = 0xCC(3) Write protection Protection by 4Kbytes Protection by sector(3) |
