The HYS 64(72)V8300GU and HYS 64(72)V16220GU are industry-standard 168-pin 8-byte Dual
In-line Memory Modules (DIMMs) which are organized as 8M × 64, 8M × 72 in 1 bank and 16M × 64
and 16M × 72 in two banks of high-speed memory arrays designed with 64M Synchronous DRAMs
(SDRAMs) for non-parity and ECC applications. The DIMMs use -7.5 speed sorted 8M × 8 SDRAM
devices in TSOP54 packages to meet the PC133-333 requirements 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 PC SDRAM Rev. 1.0 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.
