Functional Description The CY62147CV25/30/33 are high-performance CMOS static RAMs organized as 256K words by 16 bits. These devices feature 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 devices also have 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: — CY62147CV25: 2.2V–2.7V — CY62147CV30: 2.7V–3.3V — CY62147CV33: 3.0V–3.6V • Pin Compatible with CY62147V • Ultra-low active power — Typical active current: 1.5 mA @ f = 1 MHz — Typical active current: 5.5 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
