Description
The HYS 64V32300GU and HYS 72V32300GU are industry standard 168-pin 8-byte Dual in-line
Memory Modules (DIMMs) which are organized as 32M
脳
64 and 32M
脳
72 in 1 memory bank high
speed memory arrays designed with 256M Synchronous DRAMs (SDRAMs) for non-parity and
ECC applications. The DIMMs use -7 speed sorted 32M
脳
8 SDRAM devices in TSOP54 packages
to meet the PC133-222 requirement, -7.5 components for PC133-333 and -8 components for the
standard PC100 applications. Decoupling capacitors are mounted on the PC board. The PC board
design is according to INTEL鈥檚 module specification. The DIMMs have a serial presence detect,
implemented with a serial E
2
PROM using the 2-pin I
2
C protocol. The first 128 bytes are utilized by
the DIMM manufacturer 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鈥?(31.75 mm) height.
