CY7C197
256Kx1 Static RAM
Features
• High speed — 12 ns • CMOS for optimum speed/power • Low active power — 880 mW • Low standby power — 220 mW • TTL-compatible inputs and outputs • Automatic power-down when deselected vided by an active LOW Chip Enable (CE) and three-state drivers.
The CY7C197 has an automatic power-down feature, reducing the power consumption by 75% when deselected.
Writing to the device is accomplished when the Chip Enable (CE) and Write Enable (WE) inputs are both LOW.
Data on the input pin (DIN) is written into the memory location specified on the address pins (A0 through A17).
Reading the device is accomplished by taking chip enable (CE) LOW while Write Enable (WE...
