HYS64(72)V4200/8220GU
SDRAM-Modules
The HYS64(72)V4200 and HYB64(72)V8220 are an industry standard 168-pin 8-byte Dual in-line Memory Module
(DIMM) which are organised as 4M x 64, 4M x 72 in an one bank and 8M x 64, 8M x72 in two banks high speed
memory arrays designed with 64Mbit Synchronous DRAMs (SDRAMs Die Rev.B) for non-parity and ECC
application. The DIMMs use -8 and -8B speed sort 4M x 16 SDRAM devices in TSOP54 packages to meet the
PC100 requirements and -10 parts for 66 MHz bus speed applications. Decoupling capacitors are mounted on the
PC board. The PC board design is according to INTEL’s 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 t.d.b. height.
