Description
The HB52E649E12 belongs to 8-byte DIMM (Dual In-line Memory Module) family, and has been developed
as an optimized main memory solution for 8-byte processor applications. The HB52E649E12 is a 64M

1-bank Synchronous Dynamic RAM Registered Module, mounted 18 pieces of 256-Mbit SDRAM
(HM5225405BTT) sealed in TSOP package, 1 piece of PLL clock driver, 2 pieces of register driver and 1
piece of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the HB52E649E12 is 168-pin sock-
et type package (dual lead out). Therefore, the HB52E649E12 makes high density mounting possible without
surface mount technology. The HB52E649E12 provides common data inputs and outputs. Decoupling ca-
pacitors are mounted beside each TSOP on the module board.
