The HYS 64V8301 is an industry standard 168-pin 8-byte Dual in-line Memory Module (DIMM)
which is organized as 8M × 64 in an one bank high speed memory arrays designed with 128 Mbit
Synchronous DRAMs for non-parity applications. The DIMMs use -7.5 speed sorted 4M × 16
SDRAM devices in TSOP54 packages to meet the PC133-333 requirements 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.
All Infineon 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133.35 mm
long footprint.,
