EBE51UD8ABFA Overview
Description
The EBE51UD8ABFA is 64M words × 64 bits, 1 rank DDR2 SDRAM unbuffered module, mounting 8 pieces of 512M bits DDR2 SDRAM sealed in FBGA (µBGA) package. Read and write operations are performed at the cross points of the CK and the /CK.
Key Features
- 240-pin socket type dual in line memory module (DIMM) PCB height: 30.0mm Lead pitch: 1.0mm Lead-free
- 1.8V power supply
- Data rate: 533Mbps/400Mbps (max.)
- 1.8V (SSTL_18 compatible) I/O
- 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: 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
