Overview
DATA SHEET 512M bits DDR2 SDRAM EDE5108AGBG (64M words × 8 bits) Specifications • Density: 512M bits • Organization ⎯ 16M words × 8 bits × 4 banks • Package: 60-ball FBGA www.
DataSheet4U.
com ⎯ Lead-free (RoHS compliant) • Power supply: VDD, VDDQ = 1.
8V ± 0.
1V • Data rate: 667Mbps/533Mbps (max.
) • 1KB page size ⎯ Row address: A0 to A13 ⎯ Column address: A0 to A9 • Four internal banks for concurrent operation • Interface: SSTL_18 • Burst lengths (BL): 4, 8 • Burst type (BT): ⎯ Sequential (4, 8) ⎯ Interleave (4, 8) • /CAS Latency (CL): 3, 4, 5 • Precharge: auto precharge option for each burst access • Driver strength: normal/weak • Refresh: auto-refresh, self-refresh Features • Double-data-rate architecture; two data transfers per clock cycle • The high-speed data transfer is realized by the 4 bits prefetch pipelined architecture • Bi-directional differential data strobe (DQS and /DQS) is transmitted/received with data for capturing data at the receiver • DQS is edge-aligned with data for READs; centeraligned 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 • Data mask (DM) for write data • Posted /CAS by programmable additive latency for better command and data bus efficiency • Off-Chip-Driver Impedance Adjustment and On-DieTermination 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 • Refresh cycles: 8192 cycles/64ms ⎯ Average refresh period 7.
8μs at 0°C ≤ TC ≤ +85°C 3.
9μs at +85°C < TC ≤ +95°C • Operating case temperature range ⎯ TC = 0°C to +95°C Document No.
