DATA SHEET
128M bits Mobile RAM
EDL1216CASA (8M words × 16 bits)
Description
The EDL1216CA is a 128M bits Mobile RAM organized as 2,097,152 words × 16 bits × 4 banks. The Mobile RAM achieved low power consumption and high-speed data transfer using the pipeline architecture. All inputs and outputs are synchronized with the positive edge of the clock. This product is packaged in 54-ball FBGA (µBGA).
