HYS64V32220GU-8B

The HYS64V32220GU-8B are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organized as 16M x64, 16M ´ 72, 32M x64 and 32M x72 in 1 bank and 32M x 64, 32M x72, 64M x 64 and 64M x72 in two banks high speed memory arrays designed with 128M and 256M Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use -8 and -8B speed sort for 16M ´ 8 and 32M ´ 8 SDRAM devices in TSOP-54 packages to meet the PC100 requirement. Decoupling capacitors are mounted on the PC board. The PC board design is according to INTEL's PC 100 module specification.

The DIMMs of the HYS64V32220GU-8B 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 of the HYS64V32220GU-8B provide a high performance, flexible 8-byte interface in a 133.35 mm long footprint, with 1.25" (31.75 mm) height.
