HYM72V4005GU-50

The HYM72V4005GU-50 are industry standard 168-pin 8-byte Dual In-Line Memory Modules (DIMMs) which are organized as 4M x 64 and 4M x 72 high speed memory arrays designed with EDO DRAMs for non-parity and ECC applications. 2k refresh with 11 / 11 addressing and 4k refresh modules with 12 / 10 addressing are available. The DIMMs use sixteen 4M x 4 EDO DRAMs for the 4M x 64 organisation and eighteen 4M x 4 DRAMs for the 4M x 72 organisation, both in TSOPII packages. Decoupling capacitors are mounted on the PC board.

The DIMMs of the HYM72V4005GU-50 use optional serial presence detects implemented via a serial E 2PROM using the two pin I²C 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 of the HYM72V4005GU-50  provide a high performance, flexible 8-byte interface in a 133,35 mm long spacesaving footprint.
