| bogdanm | 0:9b334a45a8ff | 16 | ============================================================================== |
| bogdanm | 0:9b334a45a8ff | 17 | ##### FMC peripheral features ##### |
| bogdanm | 0:9b334a45a8ff | 18 | ============================================================================== |
| bogdanm | 0:9b334a45a8ff | 19 | [..] The Flexible memory controller (FMC) includes three memory controllers: |
| bogdanm | 0:9b334a45a8ff | 20 | (+) The NOR/PSRAM memory controller |
| bogdanm | 0:9b334a45a8ff | 21 | (+) The NAND memory controller |
| bogdanm | 0:9b334a45a8ff | 22 | (+) The Synchronous DRAM (SDRAM) controller |
| bogdanm | 0:9b334a45a8ff | 23 | |
| bogdanm | 0:9b334a45a8ff | 24 | [..] The FMC functional block makes the interface with synchronous and asynchronous static |
| bogdanm | 0:9b334a45a8ff | 25 | memories, SDRAM memories, and 16-bit PC memory cards. Its main purposes are: |
| bogdanm | 0:9b334a45a8ff | 26 | (+) to translate AHB transactions into the appropriate external device protocol |
| bogdanm | 0:9b334a45a8ff | 27 | (+) to meet the access time requirements of the external memory devices |
| bogdanm | 0:9b334a45a8ff | 28 | |
| bogdanm | 0:9b334a45a8ff | 29 | [..] All external memories share the addresses, data and control signals with the controller. |
| bogdanm | 0:9b334a45a8ff | 30 | Each external device is accessed by means of a unique Chip Select. The FMC performs |
| bogdanm | 0:9b334a45a8ff | 31 | only one access at a time to an external device. |
| bogdanm | 0:9b334a45a8ff | 32 | The main features of the FMC controller are the following: |
| bogdanm | 0:9b334a45a8ff | 33 | (+) Interface with static-memory mapped devices including: |
| bogdanm | 0:9b334a45a8ff | 34 | (++) Static random access memory (SRAM) |
| bogdanm | 0:9b334a45a8ff | 35 | (++) Read-only memory (ROM) |
| bogdanm | 0:9b334a45a8ff | 36 | (++) NOR Flash memory/OneNAND Flash memory |
| bogdanm | 0:9b334a45a8ff | 37 | (++) PSRAM (4 memory banks) |
| bogdanm | 0:9b334a45a8ff | 38 | (++) 16-bit PC Card compatible devices |
| bogdanm | 0:9b334a45a8ff | 39 | (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of |
| bogdanm | 0:9b334a45a8ff | 40 | data |
| bogdanm | 0:9b334a45a8ff | 41 | (+) Interface with synchronous DRAM (SDRAM) memories |
| bogdanm | 0:9b334a45a8ff | 42 | (+) Independent Chip Select control for each memory bank |
| bogdanm | 0:9b334a45a8ff | 43 | (+) Independent configuration for each memory bank |
| bogdanm | 0:9b334a45a8ff | 44 | |
