Description
The EBE10RD4ABFA is a 128M words × 72 bits, 1 rank DDR2 SDRAM Module, mounting 18 pieces of DDR2 SDRAM sealed in FBGA (μBGA?) package. Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 4bits prefetch-pipelined architecture. Data strobe (DQS and /DQS) both for read and write are available for high speed and reliable data bus design.
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.)
? 1.8 V (SSTL_18 compatible) I/O
? Double-data-rate architecture: two data transfers per clock cycle
? Bi-directional, 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 referenced to both edges of DQS
? Four internal banks for concurrent operation (Component)
? Burst length: 4, 8
? /CAS latency (CL): 3, 4, 5
? Auto precharge option for each burst access
? Auto refresh and self refresh modes
? 7.8μs average periodic refresh interval
? 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
? /DQS can be disabled for single-ended Data Strobe operation
? 1 piece of PLL clock driver, 2 pieces of register driver and 1 piece of serial EEPROM (2k bits EEPROM) for
Presence Detect (PD)
