HB52R1289E22-A6B/B6B
1 GB Registered SDRAM DIMM
128-Mword × 72-bit, 100 MHz Memory Bus, 2-Bank Module
(36 pcs of 64 M × 4 Components)
PC100 SDRAM
E0017H20 (Ver. 2.0)

Description
The HB52R1289E22 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 HB52R1289E22 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 HB52R1289E22 is 168-pin socket type
package (dual lead out). Therefore, the HB52R1289E22 makes high density mounting possible without
surface mount technology. The HB52R1289E22 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.
