Description
The HB52RF1289E2 belongs to 8-byte DIMM (Dual In-line Memory Module) family, and has been devel-
oped as an optimized main memory solution for 8-byte processor applications. The HB52RF1289E2 is a 64M

2-bank Synchronous Dynamic RAM Module, mounted 36 pieces of 256-Mbit SDRAM
(HM5225405BTB) sealed in TCP package, 1 piece of PLL clock driver, 3 pieces register driver and 1 piece
of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the HB52RF1289E2 is 168-pin socket
type package (dual lead out). Therefore, the HB52RF1289E2 makes high density mounting possible without
surface mount technology. The HB52RF1289E2 provides common data inputs and outputs. Decoupling ca-
pacitors are mounted beside TCP on the module board.
Note: Do not push the cover or drop the modules in order to protect from mechanical defects, which would
be electrical defects.
