The HYS 64V16302 is an industry standard 168-pin 8-byte Dual in-line Memory Module (DIMM) which is organized as 16M x 64 in an one bank high speed memory arrays designed with 256 Mbit Synchronous DRAMs for non-parity applications. The DIMMs use -7 speed sorted 16M x 16 organised 256Mbit SDRAM devices in TSOP54 packages to meet the PC133-222 requirements, 7.5 for PC133-333 and -8 parts for the standard PC100 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 2-pin I2C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128 bytes are available to the end user.
