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 -7.5 speed
sorted 16M × 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.
