CY62167EV18 MoBL 16-Mbit (1 M 16) Static RAM 16-Mbit (1 M 16) Static RAM automatic power down feature that reduces power consumption Features by 99 percent when addresses are not toggling. Place the device into standby mode when deselected (CE HIGH or CE LOW or Very high speed: 55 ns 1 2 both BHE and BLE are HIGH). The input and output pins (I/O 0 Wide voltage range: 1.65 V to 2.25 V through I/O ) are placed in a high impedance state when: the 15 device is deselected (CE HIGH or CE LOW) outputs are 1 2 Ultra low standby power disabled (OE HIGH) both Byte High Enable and Byte Low Typical standby current: 1.5 A Enable are disabled (BHE, BLE HIGH) and a write operation is Maximum standby current: 12 A in progress (CE LOW, CE HIGH and WE LOW). 1 2 Ultra low active power To write to the device, take Chip Enables (CE LOW and CE 1 2 Typical active current: 2.2 mA at f = 1 MHz 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 0 7 Easy memory expansion with CE , CE , and OE features 1 2 written into the location specified on the address pins (A through 0 Automatic power down when deselected A ). If Byte High Enable (BHE) is LOW, then data from I/O pins 19 (I/O through I/O ) is written into the location specified on the 8 15 CMOS for optimum speed and power address pins (A through A ). 0 19 Offered in Pb-free 48-ball very fine ball grid array (VFBGA) To read from the device, take Chip Enables (CE LOW and CE 1 2 packages HIGH) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data Functional Description from the memory location specified by the address pins appears on I/O to I/O . If Byte High Enable (BHE) is LOW, then data from 0 7 The CY62167EV18 is a high performance CMOS static RAM memory appears on I/O to I/O .
