204Pin DDR3L 1600 SO-DIMM 2GB Based on 256Mx8 AQD-SD3L2GN16-SQ Advantech AQD-SD3L2GN16-SQ Datasheet Rev. 1.1 2013-09-24 1 204Pin DDR3L 1600 SO-DIMM 2GB Based on 256Mx8 AQD-SD3L2GN16-SQ Description Pin Identification Pin Identification AQD-SD3L2GN16-SQ is a DDR3 Unbuffered SO-DIMM, Symbol Function non-ECC, high-speed, low power memory module that use 8pcs of 256Mx8bits DDR3L low voltage SDRAM in A0~A14, BA0~BA2 Address/Bank input FBGA package and a 2048 bits serial EEPROM on a DQ0~DQ63 Data Input / Output. 204-pin printed circuit board. AQD-SD3L2GN16-SQ is a DQS0~DQS7 Data strobes Dual In-Line Memory Module and is intended for /DQS0~/DQS7 Differential Data strobes mounting into 204-pin edge connector 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 /CS0, /CS1 DIMM Rank Select Lines. useful for a variety of high bandwidth, high performance /RAS Row Address Strobe memory system applications. /CAS Column Address Strobe Features /WE Write Enable RoHS compliant products.
