CY62167EV30 MoBL 16-Mbit (1 M 16 / 2 M 8) Static RAM 16-Mbit (1 M 16 / 2 M 8) Static RAM device features an advanced circuit design that provides an ultra Features low active current. Ultra low active current is ideal for providing More Battery Life (MoBL ) in portable applications such as TSOP I package configurable as 1 M 16 or 2 M 8 SRAM cellular telephones. The device also has an automatic power Very high speed: 45 ns down feature that reduces power consumption by 99 percent when addresses are not toggling. Place the device into standby Temperature ranges mode when deselected (CE HIGH or CE LOW or both BHE and 1 2 Industrial: 40 C to +85 C BLE are HIGH). The input and output pins (I/O through I/O ) 0 15 Automotive-A: 40 C to +85 C are placed in a high impedance state when: the device is Wide voltage range: 2.20 V to 3.60 V deselected (CE HIGH or CE LOW), outputs are disabled (OE 1 2 HIGH), both Byte High Enable and Byte Low Enable are disabled Ultra-low standby power (BHE, BLE HIGH), or a write operation is in progress (CE LOW, 1 Typical standby current: 1.5 A CE HIGH and WE LOW). 2 Maximum standby current: 12 A To write to the device, take Chip Enables (CE LOW and CE 1 2 Ultra-low active power HIGH) and Write Enable (WE) input LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O through I/O ) is Typical active current: 2.2 mA at f = 1 MHz 0 7 written into the location specified on the address pins (A through 0 Easy memory expansion with CE , CE , and OE Features 1 2 A ). If Byte High Enable (BHE) is LOW, then data from the I/O 19 pins (I/O through I/O ) is written into the location specified on 8 15 Automatic power-down when deselected the address pins (A through A ). 0 19 CMOS for optimum speed and power To read from the device, take Chip Enables (CE LOW and CE 1 2 HIGH) and Output Enable (OE) LOW while forcing the Write Offered in Pb-free 48-ball VFBGA and 48-pin TSOP I packages Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins appears Functional Description on I/O to I/O . If Byte High Enable (BHE) is LOW, then data from 0 7 The CY62167EV30 is a high performance CMOS static RAM memory appears on I/O to I/O .
