MX66C256

MX66C256 Very Low Power 32k x 8 CMOS SRAM FEATURES Vcc operation voltage : 5.0V Very low power consumption : 50 mA (Max.) write current 40 mA (Max.) read current 0.4uA (Typ.) CMOS standby current High speed access time : - 70 70ns (Max.) - 100 100ns (Max.) Input levels are CMOS-compatible Automatic power down when chip is deselected Three state outputs Fully static operation Data retention supply voltage as low as 2.0V Easy expansion with CE and OE options DESCRIPTION The MX66C256 is a high performance, very low power CMOS Static Random Access Memory organized as 32,768 words by 8 bits and operates at 5.0V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed and low power features with a typical CMOS standby current of 0.4uA and maximum access time of 70ns and 100 ns in 5V operation. Easy memory expansion is provided by an active LOW chip enable(CE), and active LOW output enable (OE) and three-state output drivers. The MX66C256 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The MX66C256 is available in the JEDEC standard 28 pin 330mil Plastic SOP, and 8mmx13.4mm TSOP (normal type).
