##### FMC peripheral features #####
|
|
==============================================================================
|
|
[..] The Flexible memory controller (FMC) includes following memory controllers:
|
|
(+) The NOR/PSRAM memory controller
|
|
(+) The NAND/PC Card memory controller
|
|
|
|
[..] The FMC functional block makes the interface with synchronous and asynchronous static
|
|
memories and 16-bit PC memory cards. Its main purposes are:
|
|
(+) to translate AHB transactions into the appropriate external device protocol
|
|
(+) to meet the access time requirements of the external memory devices
|
|
|
|
[..] All external memories share the addresses, data and control signals with the controller.
|
|
Each external device is accessed by means of a unique Chip Select. The FMC performs
|
|
only one access at a time to an external device.
|
|
The main features of the FMC controller are the following:
|
|
(+) Interface with static-memory mapped devices including:
|
|
(++) Static random access memory (SRAM)
|
|
(++) Read-only memory (ROM)
|
|
(++) NOR Flash memory/OneNAND Flash memory
|
|
(++) PSRAM (4 memory banks)
|
|
(++) 16-bit PC Card compatible devices
|
|
(++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
|
|
data
|
|
(+) Independent Chip Select control for each memory bank
|
|
(+) Independent configuration for each memory bank
|
|
