HB54A5129F2 Overview

256mb, 512mb registered ddr sdram dimm

DATA SHEET
256MB, 512MB Registered DDR SDRAM DIMM
HB54A2569F1 (32M words
×
72 bits, 1 Bank)
HB54A5129F2 (64M words
×
72 bits, 2 Banks)
Description
The HB54A2569F1, HB54A5129F2 are Double Data
Rate (DDR) SDRAM Module, mounted 256M bits DDR
SDRAM (HM5425801BTT) 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).
The HB54A2569F1 is organized as 32M
×
72
×
1 bank
mounted 9 pieces of 256M bits DDR SDRAM. The
HB54A5129F2 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.
