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 E
2
PROM using the two pin I
2
C 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.
