					Description  
					The HYS 64(72)V16300GU and HYS 64(72)V32220GU are industry-standard 168-pin 8-byte Dual  
					In-line Memory Modules (DIMMs) which are organized as 16M × 64, 16M × 72 in 1 bank and  
					32M × 64 and 32M × 72 in two banks of high-speed memory arrays designed with 128Mbit  
					Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use -7 speed  
					sorted 16M × 8 SDRAM devices in TSOP54 packages to meet the PC133-222 requirements, -7.5  
					speed sorted for PC133-333 and use -8 components for the standard PC100-222 applications.  
					Decoupling capacitors are mounted on the PC board. The PC board design is in accordance with  
					INTEL’s Module Specification. The DIMMs have Serial Presence Detect, implemented with a serial  
					E2PROM 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 INFINEON 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.
