DATA SHEET
256MB SDRAM S.O.DIMM
EBS25EC8APSA (32M words × 72 bits, 1 bank)
Description
The EBS25EC8APSA is 32M words × 72 bits, 1 bank
Synchronous Dynamic RAM Small Outline Dual In-line
Memory Module (S.O.DIMM), mounted 9 pieces of
256M bits SDRAM (EDS2508APTA) 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 S.O.DIMM: JEDEC
standard outline
• 144-pin socket type small outline dual in line memory
module (S.O.DIMM)
PCB height: 38.10mm (1.5inch )
Lead pitch: 0.80mm
• 3.3V power supply
• Clock frequency: 100MHz 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, 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
