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