HYS64V8000GU Siemens, HYS64V8000GU Datasheet - Page 2

• Manufacturer Part Number: HYS64V8000GU
• Description: 3.3V 8M x 64-Bit SDRAM Module 3.3V 8M x 72-Bit SDRAM Module
• Manufacturer: Siemens

The HYS64(72)V8000GU-10 are industry standard 168-pin 8-byte Dual in-line Memory Modules
(DIMMs) which are organised as 8M x 64 and 8M x 72 high speed memory arrays designed with
Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use eight 8M x
8 SDRAMs for the 8M x 64 organisation and an additional SDRAM for the 8M x 72 organisation.
Decoupling capacitors are mounted on the PC board.
The DIMMs have a serial presence detect, implemented with a serial E
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.
