168-Pin Unbuffered DIMM Modules

Description

The HYS 64(72)V16300GU and HYS 64(72)V32220GU are industry-standard 168-pin 8-byte Dual

In-line Memory Modules (DIMMs) which are organized as 16M

× 64, 16M × 72 in 1 bank and

32M

× 64 and 32M × 72 in two banks of high-speed memory arrays designed with 128Mbit

Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use -7 speed

sorted 16M

× 8 SDRAM devices in TSOP54 packages to meet the PC133-222 requirements, -7.5

speed sorted for PC133-333 and use -8 components for the standard PC100-222 applications.

Decoupling capacitors are mounted on the PC board. The PC board design is in accordance with

INTEL’s Module Specification. The DIMMs have Serial Presence Detect, implemented with a serial

E

and the second 128 bytes are available to the end user. All INFINEON 168-pin DIMMs provide a

high performance, flexible 8-byte interface in a 133.35 mm long footprint, with 1.25“ (31.75 mm)

height.
