mbed_official 354:e67efb2aab0e 16 =============================================================================
mbed_official 354:e67efb2aab0e 17 ##### FSMC peripheral features #####
mbed_official 354:e67efb2aab0e 18 =============================================================================
mbed_official 354:e67efb2aab0e 19 [..] The Flexible static memory controller (FSMC) includes following memory controllers:
mbed_official 354:e67efb2aab0e 20 (+) The NOR/PSRAM memory controller
mbed_official 354:e67efb2aab0e 21
mbed_official 354:e67efb2aab0e 22 [..] The FSMC functional block makes the interface with synchronous and asynchronous static
mbed_official 354:e67efb2aab0e 23 memories and SDRAM memories. Its main purposes are:
mbed_official 354:e67efb2aab0e 24 (+) to translate AHB transactions into the appropriate external device protocol.
mbed_official 354:e67efb2aab0e 25 (+) to meet the access time requirements of the external memory devices.
mbed_official 354:e67efb2aab0e 26
mbed_official 354:e67efb2aab0e 27 [..] All external memories share the addresses, data and control signals with the controller.
mbed_official 354:e67efb2aab0e 28 Each external device is accessed by means of a unique Chip Select. The FSMC performs
mbed_official 354:e67efb2aab0e 29 only one access at a time to an external device.
mbed_official 354:e67efb2aab0e 30 The main features of the FSMC controller are the following:
mbed_official 354:e67efb2aab0e 31 (+) Interface with static-memory mapped devices including:
mbed_official 354:e67efb2aab0e 32 (++) Static random access memory (SRAM).
mbed_official 354:e67efb2aab0e 33 (++) NOR Flash memory.
mbed_official 354:e67efb2aab0e 34 (++) PSRAM (4 memory banks).
mbed_official 354:e67efb2aab0e 35 (+) Independent Chip Select control for each memory bank.
mbed_official 354:e67efb2aab0e 36 (+) Independent configuration for each memory bank.
mbed_official 354:e67efb2aab0e 37
mbed_official 354:e67efb2aab0e 38 =============================================================================
mbed_official 354:e67efb2aab0e 39 ##### How to use NORSRAM device driver #####
mbed_official 354:e67efb2aab0e 40 =============================================================================
mbed_official 354:e67efb2aab0e 41
mbed_official 354:e67efb2aab0e 42 [..]
mbed_official 354:e67efb2aab0e 43 This driver contains a set of APIs to interface with the FSMC NORSRAM banks in order
mbed_official 354:e67efb2aab0e 44 to run the NORSRAM external devices.
mbed_official 354:e67efb2aab0e 45
mbed_official 354:e67efb2aab0e 46 (+) FSMC NORSRAM bank reset using the function FSMC_NORSRAM_DeInit()
mbed_official 354:e67efb2aab0e 47 (+) FSMC NORSRAM bank control configuration using the function FSMC_NORSRAM_Init()
mbed_official 354:e67efb2aab0e 48 (+) FSMC NORSRAM bank timing configuration using the function FSMC_NORSRAM_Timing_Init()
mbed_official 354:e67efb2aab0e 49 (+) FSMC NORSRAM bank extended timing configuration using the function
mbed_official 354:e67efb2aab0e 50 FSMC_NORSRAM_Extended_Timing_Init()
mbed_official 354:e67efb2aab0e 51 (+) FSMC NORSRAM bank enable/disable write operation using the functions
mbed_official 354:e67efb2aab0e 52 FSMC_NORSRAM_WriteOperation_Enable()/FSMC_NORSRAM_WriteOperation_Disable()
mbed_official 354:e67efb2aab0e 53
