DATA SHEET
512MB Unbuffered SDRAM DIMM
EBS52EC8APFA (64M words × 72 bits, 2 banks)
Description
The EBS52EC8APFA is 64M words × 72 bits, 2 banks
Synchronous Dynamic RAM Unbuffered Module,
mounted 18 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.

(DIMM)
PCB height: 34.93mm (1.38inch )
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
• Byte control by DQMB
• Refresh cycles: 8192 refresh cycles/64ms
• 2 variations of refresh
Auto refresh
Self refresh
