Hardware Description
MFC 2000 Multifunctional Peripheral Controller 2000
4.1.1.3 External Memory Space
The external memory space (up to 48 M) consists of ROM, DRAM/ARAM, Flash memory, SRAM, modem, and
variable-use spaces with assigned chip selects. Most external chip selects have programmable address ranges,
start locations, wait states, and read and write strobe timing. SRAM and DRAM/ARAM chip select controls are
battery-backed up. Refer to Figure 4-1 for the MFC2000 memory map and to Figure 4-2 for the internal memory
map.
External memory spaces include the following:
ROMCSn, ROM (4 M)
CS5n, general (4 M)
FCS0n, NOR type Flash memory (2 M)
FCS1n, NOR type Flash memory (2 M)
Address location for generating FWRn and
FRDn for the NAND type Flash memory
(Reserved)
MCSn, modem (128 K)
P80_CSn
SDAA_CSn
CS4n, optional general (128 K)
CS3n, optional general (128 K)
CS2n, optional general (512 K)
CS1n, general (1 M)
CS0n, SRAM or general (2 M)
SDRAM (For internal and Countach Imaging DSP
Subsystem) (16 M)
RAS0n, DRAM or ARAM (16 M)
RAS1n, DRAM or ARAM (16 M)
