Description The EBS25UC8APMA is 32M words × 64 bits, 1 bank Synchronous Dynamic RAM Micro Dual In-line Memory Module (Micro DIMM), mounted 8 pieces of 256M bits SDRAM sealed in µBGA 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 Micro DIMM: JEDEC standard outline • 144-pin socket type micro dual in line memory module (Micro DIMM) - PCB height: 30.00mm (1.18inch ) - Lead pitch: 0.50mm • 3.3V power supply • Clock frequency: 100MHz/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, Full page • 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
