The HYS 72Vxx3xxGR-7.5 are industry standard 168-pin 8-byte Dual in-line Memory Modules
(DIMMs) organized as 16M

72 high speed memory arrays
designed with Synchronous DRAMs (SDRAMs) for ECC applications. The 32M x 72 (256Mbyte)
registered DIMM module is available in two versions (12 or 13 row addresses). 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 E
2
PROM using
the 2-pin I
2
C 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.
