SPEAr320S
14/113
Doc ID 022508 Rev 2
The BootROM firmware has been tested with the following external serial memory
components:
●
Micron M25P and M45P families (SPI Flash)
●
STMicroelectronics M95 family (SPI EEPROM), except for M95040, M95020 and
M95010
●
ATMEL AT25F family (SPI Flash)
●
YMC Y25F family (SPI Flash)
●
Microchip/SST SST25LF family (SPI Flash)
2.5
Parallel NAND Flash controller (FSMC)
SPEAr320S integrates a flexible static memory controller able to manage external parallel
NAND Flash memories.
Main features:
●
8-/16-bit external data bus; 16-bit only supported when Mode 3 (expanded automation
mode) chip configuration is selected by software.
●
Support for up to 4 memory banks
●
Independent timing configuration and chip select signal for each memory bank
●
Fully programmable timings:
–
wait states (up to 31)
–
bus turnaround cycles (up to 15)
–
output enable and write enable delays (up to 15)
●
External asynchronous wait control
●
Internal AHB bus burst transfer support to reduce Flash memory access time
The BootROM firmware directly supports the external NAND Flash components shown in
Table 2.
