Functional DescriptionThe CY62256N is a high performance CMOS static RAMorganized as 32K words by 8 bits. Easy memory expansion isprovided by an active LOW chip enable (CE) and active LOWoutput enable (OE) and tristate drivers. This device has anautomatic power-down feature, reducing the power consumptionby 99.9 percent when deselected.An active LOW write enable signal (WE) controls thewriting/reading operation of the memory. When CE and WEinputs are both LOW, data on the eight data input/output pins(I/O0 through I/O7) is written into the memory location addressedby the address present on the address pins (A0 through A14).Reading the device is accomplished by selecting the device andenabling the outputs, CE and OE active LOW, while WE remainsinactive or HIGH. Under these conditions, the contents of thelocation addressed by the information on address pins arepresent on the eight data input/output pins.The input/output pins remain in a high impedance state unlessthe chip is selected, outputs are enabled, and write enable (WE)is HIGH.For a complete list of related documentation, click here.
