Timing parameters For NOR/SRAM Banks.

Field Documentation

uint32_t FSMC_AccessMode
             Specifies the asynchronous access mode. 

This parameter can be a value of FSMC_Access_Mode

uint32_t FSMC_AddressHoldTime
        Defines the number of HCLK cycles to configure

the duration of the address hold time. This parameter can be a value between 0 and 0xF.

Note
This parameter is not used with synchronous NOR Flash memories.
uint32_t FSMC_AddressSetupTime
       Defines the number of HCLK cycles to configure

the duration of the address setup time. This parameter can be a value between 0 and 0xF.

Note
This parameter is not used with synchronous NOR Flash memories.
uint32_t FSMC_BusTurnAroundDuration
  Defines the number of HCLK cycles to configure

the duration of the bus turnaround. This parameter can be a value between 0 and 0xF.

Note
This parameter is only used for multiplexed NOR Flash memories.
uint32_t FSMC_CLKDivision
            Defines the period of CLK clock output signal, expressed in number of HCLK cycles.

This parameter can be a value between 1 and 0xF.

Note
This parameter is not used for asynchronous NOR Flash, SRAM or ROM accesses.
uint32_t FSMC_DataLatency
            Defines the number of memory clock cycles to issue

to the memory before getting the first data. The parameter value depends on the memory type as shown below:

  • It must be set to 0 in case of a CRAM
  • It is don't care in asynchronous NOR, SRAM or ROM accesses
  • It may assume a value between 0 and 0xF in NOR Flash memories with synchronous burst mode enable
uint32_t FSMC_DataSetupTime
          Defines the number of HCLK cycles to configure

the duration of the data setup time. This parameter can be a value between 0 and 0xFF.

Note
This parameter is used for SRAMs, ROMs and asynchronous multiplexed NOR Flash memories.
