Description
The HYS 72Vxx3xxGR-7 and -7.5 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs)
organized as 16M × 72, 32M x 72, 64M × 72, 128M × 72 and 256M x 72 high speed memory arrays designed with
Synchronous DRAMs (SDRAMs) for ECC applications. All control and address signals are registered on-DIMM
and the design incorporates a PLL circuit for the Clock inputs. Use of an on-board register reduces capacitive
loading on the input signals but are delayed by one cycle in arriving at the SDRAM devices. Decoupling capacitors
are mounted on the PC board. The DIMMs use a serial presence detects scheme implemented via a serial
E²PROM using the 2-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 Infineon 168-pin DIMMs provide a high performance, flexible 8-byte
interface in a 133.35 mm long footprint.
