Fast Access times: 150ns @ 3.3V – 5V
x8/x16 PCMCIA standard interface
Packaged in PCMCIA type I or type II housing (type II
for cards with extended battery backup time), the WEDC
SRAM SRV30 series is based on high density and super
low power SRAM memory devices, providing densities
from 2MBytes to 16MBytes.
Low Power CMOS technology provides very low
power and reliable data retention characteristics
• standby current < 100µA typical
The SRV30 series of SRAM memory cards has a universal
wide power supply (3V to 5V) and operates at speeds as
high as 150ns. The cards are based on advanced CMOS
technology providing very low power and reliable data
retention characteristics. WEDC’s SRAM cards contain
a rechargeable lithium battery and recharge circuitry,
eliminating the need for replaceable batteries found in
many SRAM cards.
