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