DATA SHEET
512MB Registered DDR SDRAM DIMM
HB54A5129F1-B75B/10B (64M words × 72 bits, 1 Rank) _Description
The HB54A5129F1 is a 64M × 72 × 1 rank Double Data
Rate (DDR) SDRAM Module, mounted 18 pieces of
256Mbits DDR SDRAM sealed in TSOP package, 1
piece of PLL clock driver, 2 pieces of register driver
Eand 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
O^{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).
L _{Therefore, it makes high density mounting possible}
without surface mount technology. It provides common
data inputs and outputs. Decoupling capacitors are
Product ^{mounted beside each TSOP on the module board.}
