Asynchronous SRAMs

ISSI Asynchronous SRAMs are offered in x8, x16, and x32 configurations. These devices are available in high-speed, low-power, high-speed/low-power, PowerSaver lower power, and automotive versions with long-term support offered by ISSI's commitment to the continued development of these products. ISSI Asynchronous SRAMs feature a wide offering of densities (64K to 16M), speeds (8ns to 55ns), supply voltages (1.65V to 5V), and temperature ranges (commercial, industrial, and automotive). These devices are available in a variety of packages (BGA, SOJ, SOP, sTSOP, and TSOP) to fit a variety of design needs.
