Functional Description[1]
The CY7C197D is a high-performance CMOS static RAM organized as 256K words by 1 bit. Easy memory expansion is provided by an active LOW Chip Enable (CE) and three-state drivers. The CY7C197D has an automatic power-down feature, reducing the power consumption when deselected.

• Pin- and function-compatible with CY7C197B
• High speed
    — tAA = 10 ns
• CMOS for optimum speed/power
• Low active power
    — ICC = 60 mA @ 10 ns
• Low CMOS standby power
    — ISB2 = 3 mA
• TTL-compatible inputs and outputs
• Data retention at 2.0V
• Automatic power-down when deselected
• Available in Pb-Free Packages
