CY62158EV30 MoBL 8-Mbit (1024 K 8) Static RAM 8-Mbit (1024 K 8) Static RAM Features Functional Description Very high speed: 45 ns The CY62158EV30 is a high performance CMOS static RAM organized as 1024K words by 8 bits. This device features Wide voltage range: 2.20 V3.60 V advanced circuit design to provide ultra low active current. This Pin compatible with CY62158DV30 is ideal for providing More Battery Life (MoBL ) in portable applications such as cellular telephones. The device also has an Ultra low standby power automatic power down feature that significantly reduces power Typical standby current: 2 A consumption. Placing the device into standby mode reduces Maximum standby current: 8 A power consumption significantly when deselected (CE HIGH or 1 CE LOW). The eight input and output pins (I/O through I/O ) Ultra low active power 2 0 7 are placed in a high impedance state when the device is Typical active current: 1.8 mA at f = 1 MHz deselected (CE HIGH or CE LOW), the outputs are disabled 1 2 Easy memory expansion with CE , CE , and OE features 1 2 (OE HIGH), or a write operation is in progress (CE LOW and 1 CE HIGH and WE LOW). 2 Automatic power down when deselected To write to the device, take Chip Enables (CE LOW and CE 1 2 CMOS for optimum speed/power HIGH) and Write Enable (WE) input LOW. Data on the eight I/O pins (I/O through I/O ) is then written into the location specified Offered in Pb-free 48-ball VFBGA and 44-pin TSOP II 0 7 on the address pins (A through A ). packages 0 19 To read from the device, take Chip Enables (CE LOW and CE 1 2 HIGH) and OE LOW while forcing the WE HIGH. Under these conditions, the contents of the memory location specified by the address pins appear on the I/O pins. See Truth Table on page 11 for a complete description of read and write modes.
