Description
The HB52F649E1 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 HB52F649E1 is a 64M

72
×
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, 3 pieces of register driver and 1
piece of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the HB52F649E1 is 168-pin socket
type package (dual lead out). Therefore, the HB52F649E1 makes high density mounting possible without
surface mount technology. The HB52F649E1 provides common data inputs and outputs. Decoupling
capacitors are mounted beside each TSOP on the module board.
