EBS21RC2ACNA

DATA SHEET 2GB Registered SDRAM DIMM EBS21RC2ACNA (256M words × 72 bits, 2 banks) Description The EBS21RC2ACNA is 256M words × 72 bits, 2 banks Synchronous Dynamic RAM Registered Module, mounted 72 pieces of 256M bits SDRAM sealed in TCP package. This module provides high density and large quantities of memory in a small space without utilizing the surface mounting technology. Decoupling capacitors are mounted on power supply line for noise reduction. Note: Do not push the cover or drop the modules in order to protect from mechanical defects, which would be electrical defects. Features Fully compatible with 8 bytes DIMM: JEDEC standard outline 168-pin socket type dual in line memory module (DIMM)  PCB height: 41.91mm (1.65inch )  Lead pitch: 1.27mm 3.3V power supply Clock frequency: 133MHz (max.) LVTTL interface Data bus width: × 72 ECC Single pulsed /RAS 4 Banks can operates simultaneously and independently Burst read/write operation and burst read/single write operation capability Programmable burst length (BL): 1, 2, 4, 8 2 variations of burst sequence  Sequential  Interleave Programmable /CAS latency (CL): 2, 3 Registered inputs with one clock delay Byte control by DQMB Refresh cycles: 8192 refresh cycles/64ms 2 variations of refresh  Auto refresh  Self refresh 1 piece of PLL clock driver, 3 pieces of register driver and 1 piece of serial EEPROM (2k bits) for Presence Detect (SPD) on PCB.
