HYS 64(72)V16200/3222(0)0/64220GU
SDRAM Modules
The HYS 64/72V1600, HYS 64/72V32220, HYS 64/72V32200 and HYS 64/72V64220 are industry
standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organized as 16M × 64,
16M × 72, 32M × 64 and 32M × 72 in 1 bank and 32M × 64, 32M × 72, 64M × 64 and 64M × 72 in
two banks high speed memory arrays designed with 128M and 256M Synchronous DRAMs
(SDRAMs) for non-parity and ECC applications. The DIMMs use -8 and -8B speed sort for 16M × 8
and 32M × 8 SDRAM devices in TSOP-54 packages to meet the PC100 requirement. Decoupling
capacitors are mounted on the PC board. The PC board design is according to INTEL’s PC 100
module specification.
The DIMMs have a 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 SIEMENS 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.
