CMOS standby current High speed access time : -55 55ns -70 70ns Automatic power down when chip is deselected Three state outputs and TTL compatible Fully static operation Data retention supply voltage as low as 1.5V Easy expansion with CE2, CE1, and OE options „ DESCRIPTION The STC62WV2568 is a high performance, very low power CMOS Static Random Access Memory organized as 262,144 words by 8 bits and operates from a wide range of 2.4V to 5.5V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed and low power features with a typical CMOS standby current of 0.3uA at 3.0V /25oC and maximum access time of 55ns at 3.0V /85oC. Easy memory expansion is provided by an active LOW chip enable (CE1), an active HIGH chip enable (CE2), and active LOW output enable (OE) and three-state output drivers. The STC62WV2568 has an automatic power down feature, reducing the power consumption...
