CY62126ESL MoBL Automotive 1-Mbit (64 K 16) Static RAM 1-Mbit (64 K 16) Static RAM applications such as cellular telephones. The device also has an Features automatic power down feature that significantly reduces power consumption when addresses are not toggling. Placing the Very high speed: 45 ns device into standby mode reduces power consumption by more Wide voltage range: 2.2 V to 3.6 V and 4.5 V to 5.5 V than 99 percent when deselected (CE HIGH). The input and output pins (I/O through I/O ) are placed in a high impedance 0 15 Ultra low standby power state when the device is deselected (CE HIGH), the outputs are Typical standby current: 1 A disabled (OE HIGH), both Byte High Enable and Byte Low Maximum standby current: 4 A Enable are disabled (BHE, BLE HIGH) or during a write operation (CE LOW and WE LOW). Ultra low active power Typical active current: 1.3 mA at f = 1 MHz To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data Easy memory expansion with CE, and OE features from I/O pins (I/O through I/O ) is written into the location 0 7 Automatic power down when deselected specified on the address pins (A through A ). If Byte High 0 15 Enable (BHE) is LOW, then data from I/O pins (I/O through 8 Complementary metal oxide semiconductor (CMOS) for I/O ) is written into the location specified on the address pins 15 optimum speed and power (A through A ). 0 15 Available in Pb-free 44-Pin thin small outline package (TSOP) II To read from the device, take Chip Enable (CE) and Output package Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory Functional Description location specified by the address pins appear on I/O to I/O . If 0 7 Byte High Enable (BHE) is LOW, then data from memory The CY62126ESL is a high performance CMOS static RAM appears on I/O to I/O . See the Truth Table on page 11 for a 8 15 organized as 64K words by 16 bits. This device features complete description of read and write modes. advanced circuit design to provide ultra low active current.
