Functional Description The CY62146CV30 is a high-performance CMOS static RAM organized as 256K words by 16 bits. This device features advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery Life™ (MoBL™) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces power consumption by 80% when addresses are not toggling. Features • High speed: — 55 ns and 70 ns availability • Voltage range: — CY62146CV30: 2.7V – 3.3V • Pin compatible with CY62146V • Ultra-low active power — Typical active current: 1.5 mA @ f = 1 MHz — Typical active current: 7 mA @ f = fmax (70 ns speed) • Low standby power • Easy memory expansion with CE and OE features • Automatic power-down when deselected • CMOS for optimum speed/power
