EDE5104AGSE-5C-E

• Power supply:  VDD, VDDQ = 1.8V ± 0.1V
• Double-data-rate architecture: two data transfers per clock cycle
• Bi-directional, differential data strobe (DQS and /DQS) is transmitted/received with data,
   to be used in capturing  data at the receiver
• DQS is edge aligned with data for READs: center-aligned with data for WRITEs
• Differential clock inputs (CK and /CK)
• DLL aligns DQ and DQS transitions with CK transitions
• Commands entered on each positive CK edge: data and data mask referenced to both edges of DQS 
• Four internal banks for concurrent operation
• Data mask (DM) for write data
• Burst lengths: 4, 8
• /CAS Latency (CL): 3, 4, 5
• Auto precharge operation for each burst access
• Auto refresh and self refresh modes
• Average refresh period  7.8µs at 0°C  TC  +85°C 
                                          3.9µs at +85°C < TC +95°C
• SSTL_18 compatible I/O
• Posted CAS by programmable additive latency for better command and data bus efficiency
• Off-Chip-Driver Impedance Adjustment and On-Die-Termination for better signal quality
• Programmable RDQS, /RDQS output for making * 8 organization compatible to *4 organization
• /DQS, (/RDQS) can be disabled for single-ended Data Strobe operation.
• FBGA (µBGA) package with lead free solder (Sn-Ag-Cu)  RoHS compliant
