CY621472EV30 4-Mbit 256 K x 16 Static RAM 4-Mbit 256 K x 16 Static RAM • Very high speed 45 ns • Temperature range Industrial °C to +85 °C • Wide voltage range V to V • Ultra low standby power Typical standby current 1 uA Maximum standby current 7 uA Industrial • Ultra low active power Typical active current 2 mA at f = 1 MHz • Easy memory expansion with CE1, CE2, and OE Features • Automatic power down when deselected • Complementary metal oxide semiconductor CMOS for optimum speed and power • Available in Pb-free 44-pin thin small outline package TSOP II package • Byte power down feature Functional Description The CY621472EV30 is a high performance CMOS static RAM SRAM organized as 256K words by 16 bits. This device features advanced circuit design to provide ultra low active current. It is ideal for providing More Battery Life in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption when addresses are not toggling. Placing the device into standby mode reduces power consumption by more than 99 percent when deselected CE1 HIGH or CE2 LOW or both BLE and BHE are HIGH . The input and output pins I/O0 through I/O15 are placed in a high impedance state when: • Deselected CE1 HIGH or CE2 LOW • Outputs are disabled OE HIGH • Both Byte High Enable and Byte Low Enable are disabled BHE, BLE HIGH • Write operation is active CE1 LOW and CE2 HIGH and WE LOW To write to the device, take Chip Enable CE1 LOW and CE2 HIGH and Write Enable WE inputs LOW. If Byte Low Enable BLE is LOW, then data from I/O pins I/O0 through I/O7 is written into the location specified on the address pins A0 through A17 . If Byte High Enable BHE is LOW, then data from I/O pins I/O8 through I/O15 is written into the location specified on the address pins A0 through A17 . To read from the device, take Chip Enable CE1 LOW and CE2 HIGH and Output Enable OE LOW while forcing the Write Enable WE HIGH. If Byte Low Enable BLE is LOW, then data from the memory location specified by the address pins appear on I/O0 to I/O7. If Byte High Enable BHE is LOW, then data from memory appears on I/O8 to I/O15. See the Truth Table on page 10 for a complete description of read and write modes.
