Description
The HB54A2569F1U, HB54A5129F2U are Double
Data Rate (DDR) SDRAM Module, mounted 256M bits
DDR SDRAM (HM5425801BTT) sealed in TSOP
package, and 1 piece of serial EEPROM (2k bits
EEPROM) for Presence Detect (PD).
The HB54A2569F1U is organized as 32M
×

×
1
bank mounted 9 pieces of 256M bits DDR SDRAM.
The HB54A5129F2U is organized as 32M
×
72
×
2
banks mounted 18 pieces of 256M bits DDR SDRAM.
Read and write operations are performed at the cross
points of the CK and the /CK. This high-speed data
transfer is realized by the 2 bits prefetch-pipelined
architecture. Data strobe (DQS) both for read and
write are available for high speed and reliable data bus
design. By setting extended mode register, the on-chip
Delay Locked Loop (DLL) can be set enable or disable.
An outline of the products is 184-pin socket type
package (dual lead out). Therefore, it makes high
density mounting possible without surface mount
technology. It provides common data inputs and
outputs. Decoupling capacitors are mounted beside
each TSOP on the module board.
