HB52R329E2-D

256 MB Registered SDRAM DIMM

32-Mword × 72-bit, 100 MHz Memory Bus, 2-Bank Module

(36 pcs of 16 M × 4 Components)

PC100 SDRAM

ADE-203-966 (Z)

Preliminary, Rev. 0.0

Nov. 3, 1998

Description

The HB52R329E2 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 HB52R329E2 is a

16M × 72 × 2-bank Synchronous Dynamic RAM Module, mounted 36 pieces of 64-Mbit SDRAM

(HM5264405DTB) sealed in TCP package and 1 piece of PLL clock driver (CDC2510B), 3 pieces register

driver (ALVC162835), 1 piece of inverter and 1 piece of serial EEPROM (2-kbit EEPROM) for Presence

Detect (PD). An outline of the HB52R329E2 is 168-pin socket type package (dual lead out). Therefore,

the HB52R329E2 makes high density mounting possible without surface mount technology. The

HB52R329E2 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.

PLL clock driver (CD2510B) of Hitachi is the same characteristics as TI’s one (CD2510A).
