Description The EBS52UC8APFA is 64M words × 64 bits, 2 banks Synchronous Dynamic RAM Registered Module, mounted 16 pieces of 256M bits SDRAM sealed in TSOP 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. Features • Fully compatible with 8 bytes DIMM: JEDEC standard outline • 168-pin socket type dual in line memory module (DIMM) - PCB height: 34.93mm (1.38inch ) - Lead pitch: 1.27mm • 3.3V power supply • Clock frequency: 133MHz (max.) • LVTTL interface • Data bus width: × 64 non-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 • Byte control by DQMB • Refresh cycles: 8192 refresh cycles/64ms • 2 variations of refresh - Auto refresh - Self refresh
