HYS64V8220GU-8

The HYS64V8220GU-8 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 of the HYS64V8220GU-8 have a serial presence detect, implemented with a serial E²PROM using the two pin I2^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 of the HYS64V8220GU-8 provide a high performance, flexible 8-byte interface in a 133,35 mm long footprint, with t.d.b. height.
