CY7C168A-20PXC Infineon

CY7C168A 4 K 4 RAM 4 K 4 RAM Features Functional Description The CY7C168A is a high-performance CMOS static RAM Automatic power-down when deselected organized as 4096 by 4-bits. Easy memory expansion is Complementary metal oxide semiconductor (CMOS) for provided by an active LOW chip enable (CE) and three-state optimum speed/power drivers. The CY7C168A has an automatic power-down feature, reducing the power consumption by 77% when deselected. High speed Writing to the device is accomplished when the chip select (CE) t = 20 ns AA and write enable (WE) inputs are both LOW. Data on the four Low active power data input/output pins (I/O through I/O ) is written into the 0 3 495 mW memory location specified on the address pins (A through A ). 0 11 Low standby power Reading the device is accomplished by taking the chip enable (CE) LOW, while write enable (WE) remains HIGH. Under these 110 mW conditions, the contents of the location specified on the address TTL-compatible inputs and outputs pins will appear on the four data input/output pins (I/O through 0 I/O ). V of 2.2 V 3 IH The input/output pins remain in a high-impedance state when Capable of withstanding greater than 2001 V electrostatic chip enable (CE) is HIGH or write enable (WE) is LOW. discharge A die coat is used to insure alpha immunity.
