Description
The HB52RF1289E2U 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 HB52RF1289E2U
is a 64M × 72 × 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 HB52RF1289E2U is 168-pin socket
type package (dual lead out). Therefore, the HB52RF1289E2U makes high density mounting possible
without surface mount technology. The HB52RF1289E2U provides common data inputs and outputs.
Decoupling capacitors 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.
