Packaged in PCMCIA type I housing the WEDC SRAM
SEA series is based on 1 or 4Mbit SRAM memories,
providing densities from 128 Kbytes to 512 Kbytes.
Low Power CMOS technology provides very low
power and reliable data retention characteristics
• Operating current 80mA maximum
The SEA series of SRAM memory cards requires a 5V
power supply and operates at speeds to 150ns. The cards
are based on advanced CMOS technology providing very
low power and reliable data retention characteristics.
