Specifications
Bus state controller
(BSC)
•
Address space divided into five areas (CS0 to CS4, max. linear 32 Mbytes
each)
Memory types such as DRAM, synchronous DRAM, burst ROM, can
be specified for each area
Two synchronous DRAM spaces (CS2, CS3); CS3 also supports
DRAM
Bus width (8, 16, 32 bits) can be selected for each area
Wait state insertion control for each area
Control signal output for each area
Endian can be set for CS2 and CS4
•
Cache
Cache area/cache-through area selection by access address
Selection of write-through or write-back mode
•
Refresh
functions
CAS
-before-
RAS
refreshing (auto refreshing) or self-refreshing
Refresh interval settable by means of refresh counter and clock select
setting
Concentrated refreshing according to refresh count setting
(1, 2, 4, 6, 8)
Refresh request output possible (REFOUT)
•
Direct DRAM interface
Multiplexed row address/column address output
Fast page mode burst transfer and continuous access when reading
EDO mode
TP cycle generation to secure
RAS
precharge time
•
Direct synchronous DRAM interface
Multiplexed row address/column address output
Bank-active mode (valid for CS3 only)
Selection of burst read/single write mode or burst read/burst write
mode
•
Bus arbitration (
BRLS
,
BGR
)
•
Refresh counter can be used as interval timer
Interrupt request generated on compare match (CMI interrupt request
signal)
