CY7C199C
256K 32K x 8 Static RAM
• Fast access time 12 ns
• Wide voltage range 5.0V ± 10% 4.5V to 5.5V
• CMOS for optimum speed/power
• Inputs and Outputs
• 2.0V Data Retention
• Low CMOS standby power
• Automated Power-down when deselected
• Available in Pb-free and non Pb-free 28-pin 300-Mil

Molded SOJ, 28-pin 300-Mil DIP and 28-pin TSOP I packages

The CY7C199C is a high-performance CMOS Asynchronous SRAM organized as 32K by 8 bits that supports an asynchronous memory interface. The device features an automatic power-down feature that significantly reduces power consumption when deselected.
