HYS72V4220GU-10

The HYS72V4220GU-10 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organised as 2M x 64, 2M x 72 in 1 bank and 4M x 64 and 4M x 72 in two banks high speed memory arrays designed with Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use -8 speed sort 2M x 8 SDRAM devices in TSOP44 packages to meet the PC100 requirement. Modules HYS72V4220GU-10 which use -10 parts are suitable for PC66 applications only. Decoupling capacitors are mounted on the PC board. The PC board design is according to INTEL' s PC SDRAM Rev.1.0 module specification.

The DIMMs of the HYS72V4220GU-10 have a serial presence detect, implemented with a serial E 2PROM 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
