HYS72V16220GU-8

The HYS72V16220GU-8 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organized as 8M x 64, 8M x 72 in 1 bank and 16M x 64 and 16M x72 in two banks high speed memory arrays designed with 64M Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use -8 and -8B speed sort  8M 8 SDRAM devices in TSOP-54 packages to meet the PC100 requirement. Modules which use -10 parts are suitable for PC66 applications only. Decoupling capacitors are mounted on the PC board. The PC board design of the HYS72V16220GU-8 is according to INTEL's PC SDRAM Rev. 1.0 module specification. The DIMMs have a serial presence detect, implemented with a serial E2PROM using the two pin I²C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128 bytes are available to the end user.

All SIEMENS 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.
