240PIN DDR3 1600 UDIMM JM1600KLN-2G 2048MB With 256Mx8 CL11 Description Placement The JM1600KLN-2G is a 256M x 64bits DDR3-1600 unbuffered DIMM. The JM1600KLN-2G consists of 8pcs 256Mx8bits DDR3 SDRAMs in FBGA packages and a 2048 bits serial EEPROM on a 240-pin printed circuit board. The JM1600KLN-2G is a Dual In-Line Memory Module and is intended for mounting into 240-pin edge connector sockets. B Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operation frequencies, E D programmable latencies allow the same device to be F useful for a variety of high bandwidth, high performance A memory system applications. Features • RoHS compliant products. • JEDEC standard 1.5V ± 0.075V Power supply • VDDQ=1.5V ± 0.075V • Clock Freq: 800MHZ for 1600Mb/s/Pin. • Programmable CAS Latency: 6, 7, 8, 9, 10, 11 • Programmable Additive Latency (Posted /CAS): 0, C G H I M J K CL-2 or CL-1 clock • Programmable /CAS Write Latency (CWL) = 8 • 8 bit pre-fetch • Bi-directional Differential Data-Strobe • Internal calibration through ZQ pin • On Die Termination with ODT pin • Serial presence detect with EEPROM • Asynchronous reset Transcend Information Inc.
