Features and Applications

The CY7C199D is a high performance CMOS static RAM organized as 32,768 words by 8-bits. Easy memory expansion is provided by an active LOW chip enable (CE), an active LOW output enable (OE) and tri-state drivers.

This device has an automatic power-down feature, reducing the power consumption when deselected. The input and output pins (I/O0 through I/O7) are placed in a high impedance state when the device is deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE LOW and WE LOW). Write to the device by taking chip enable (CE) and write enable (WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A14).
