240Pin DDR3 1333 UDIMM 1GB Based on 128Mx8 AQD-D31GN13-SX Advantech AQD-D31GN13-SX Datasheet Rev. 1.1 2013-09-24 1 240Pin DDR3 1333 UDIMM 1GB Based on 128Mx8 AQD-D31GN13-SX Description Pin Identification Pin Identification AQD-D31GN13-SX is a DDR3 Unbuffered, non-ECC Symbol Function high-speed, low power memory module that use 8 pcs of 128Mx8bits DDR3 SDRAM in FBGA package and a 2048 A0~A13, BA0~BA2 Address/Bank input bits serial EEPROM on a 240-pin printed circuit board. DQ0~DQ63 Bi-direction data bus. AQD-D31GN13-SX is a Dual In-Line Memory Module and DQS0~DQS7 Data strobes is intended for mounting into 240-pin edge connector /DQS0~/DQS7 Differential Data strobes sockets. CK0, /CK0,CK1, /CK1 Clock Input. (Differential pair) Synchronous design allows precise cycle control with the CKE0, CKE1 Clock Enable Input. use of system clock. Data I/O transactions are possible ODT0, ODT1 On-die termination control line on both edges of DQS. Range of operation frequencies, programmable latencies allow the same device to be /S0, /S1 DIMM rank select lines. useful for a variety of high bandwidth, high performance /RAS Row address strobe memory system applications. /CAS Column address strobe /WE Write Enable Features DM0~DM7 Data masks/high data strobes RoHS compliant products.
