512MB Registered DDR SDRAM DIMM
HB54A5129F1U-A75B/B75B/10B (64M words × 72 bits, 1 Bank)
Description
Features
The HB54A5129F1U is a 64M × 72 × 1 bank Double
Data Rate (DDR) SDRAM Module, mounted 18 pieces
of 256Mbits DDR SDRAM (HM5425401BTT) sealed in
TSOP package, 1 piece of PLL clock driver, 2 pieces of
register driver and 1 piece of serial EEPROM (2k bits
EEPROM) for Presence Detect (PD). 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-bit 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.
