The industrial SFE series organized as a one rank 1024Mx72, high-speed memory array or two ranks 2048Mx72, high-speed memory array. The module uses nine 512Mx8(4GB), 1Gx8(8GB), eighteen 1Gx8 (16GB) DDR4 SDRAMs in BGA packages. This DIMM is manufactured using raw cards developed for broad industry use as reference designs. The use of these common design files minimizes electrical variation between suppliers. DDR4 SDRAM SODIMM provide a high-performance, flexible 8-byte interface in a space-saving footprint.
The DIMM is intended for use in applications operating of 1200MHz or 1333MHz clock speeds and achieves high-speed data transfer rates of 3200Mbps. Prior to any access operation, the device CAS latency and burst/length/operation type must be programmed into the DIMM by address inputs A0-A15(1Gx8) and I/O inputs BA0, BA1, BG0, BG1 using the mode register set cycle. The DIMM uses serial presence-detect implemented via a serial EEPROM using a standard IIC protocol.
