EDE5108GBSA

Features:

1.8V power supply
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
7.8s average periodic refresh interval
1.8V (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.
BGA package is lead free solder (Sn-Ag-Cu)
