HYS64(72)V2100G(C)U-10
2M x 64/72 SDRAM-Module
The HYS64(72)V21)00G(C)U-10 are industry standard 168-pin 8-byte Dual in-line Memory
Modules (DIMMs) which are organised as 2M x 64 and 2M x 72 high speed memory arrays
designed with Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs
use eight 2M x 8 SDRAMs for the 2M x 64 organisation and an additional SDRAM for the 2M x 72
organisation. Decoupling capacitors are mounted on the PC board.
The DIMMs 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.
