HYM 64(72)V1605/45GU-50/-60
16M x 64/72 DRAM Module
The HYM64(72)V1605/45GU-50/-60 are industry standard 168-pin 8-byte Dual In-Line Memory
Modules (DIMMs) which are organized as 16M x 64 and 16M x 72 high speed memory arrays
designed with EDO DRAMs for non-parity and ECC applications. 4k refresh with 12 / 12 addressing
and 8k refresh modules with 13 / 11 addressing are available. The DIMMs use sixteen 16M x 4 EDO
DRAMs for the 16M x 64 organisation and eighteen 16M x 4 DRAMs for the 16M x 72 organisation,
both in TSOPII packages. Decoupling capacitors are mounted on the PC board.
The DIMMs use optional serial presence detects implemented via 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 of serial PD data are available to the customer.
All 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133,35 mm long space-
saving footprint.
