Field Documentation

CASLatency

uint32_t FMC_SDRAM_InitTypeDef::CASLatency

Defines the SDRAM CAS latency in number of memory clock cycles. This parameter can be a value of FMC SDRAM CAS Latency.

ColumnBitsNumber

uint32_t FMC_SDRAM_InitTypeDef::ColumnBitsNumber

Defines the number of bits of column address. This parameter can be a value of FMC SDRAM Column Bits number.

InternalBankNumber

uint32_t FMC_SDRAM_InitTypeDef::InternalBankNumber

Defines the number of the device's internal banks. This parameter can be of FMC SDRAM Internal Banks Number.

MemoryDataWidth

uint32_t FMC_SDRAM_InitTypeDef::MemoryDataWidth

Defines the memory device width. This parameter can be a value of FMC SDRAM Memory Bus Width.

ReadBurst

uint32_t FMC_SDRAM_InitTypeDef::ReadBurst

This bit enable the SDRAM controller to anticipate the next read commands during the CAS latency and stores data in the Read FIFO. This parameter can be a value of FMC SDRAM Read Burst.

ReadPipeDelay

uint32_t FMC_SDRAM_InitTypeDef::ReadPipeDelay

Define the delay in system clock cycles on read data path. This parameter can be a value of FMC SDRAM Read Pipe Delay.

RowBitsNumber

uint32_t FMC_SDRAM_InitTypeDef::RowBitsNumber

Defines the number of bits of column address. This parameter can be a value of FMC SDRAM Row Bits number.

SDBank

uint32_t FMC_SDRAM_InitTypeDef::SDBank

Specifies the SDRAM memory device that will be used. This parameter can be a value of FMC SDRAM Bank

SDClockPeriod

uint32_t FMC_SDRAM_InitTypeDef::SDClockPeriod

Define the SDRAM Clock Period for both SDRAM devices and they allow to disable the clock before changing frequency. This parameter can be a value of FMC SDRAM Clock Period.

WriteProtection

uint32_t FMC_SDRAM_InitTypeDef::WriteProtection

Enables the SDRAM device to be accessed in write mode. This parameter can be a value of FMC SDRAM Write Protection.
