CY7C1024DV33 3-Mbit (128K 24) Static RAM Features Functional Description High speed The CY7C1024DV33 is a high performance CMOS static RAM organized as 128 K words by 24 bits. This device has an t = 10 ns AA automatic power-down feature that significantly reduces power Low active power consumption when deselected. I = 175 mA at f = 100 MHz CC To write to the device, enable the chip (CE LOW, CE HIGH, 1 2 Low CMOS standby power and CE LOW), while forcing the Write Enable (WE) input LOW. 3 I = 25 mA SB2 To read from the device, enable the chip by taking CE LOW, CE 1 2 HIGH, and CE LOW while forcing the Output Enable (OE) LOW 3 Operating voltages of 3.3 0.3 V and the Write Enable (WE) HIGH. See the Truth Table on page 2.0 V data retention 7 for a complete description of Read and Write modes. The 24 I/O pins (I/O to I/O ) are placed in a high impedance Automatic power-down when deselected 0 23 state when the device is deselected (CE HIGH, CE LOW, or 1 2 Transistor-transistor logic (TTL) compatible inputs and outputs CE HIGH) or when the output enable (OE) is HIGH during a 3 write operation. (CE LOW, CE HIGH, CE LOW, and WE 1 2 3 Easy memory expansion with CE , CE , and CE features 1 2 3 LOW).
