CY62127DV30 MoBL 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 by 90% when addresses are not toggling. The Temperature ranges device can be put into standby mode reducing power Industrial: 40 C to 85 C consumption by more than 99% when deselected (CE HIGH or Very high speed: 55 ns both BHE and BLE are HIGH). The input/output pins (I/O 0 through I/O ) are placed in a high-impedance state when: 15 Wide voltage range: 2.2 V to 3.6 V deselected (CE HIGH), outputs are disabled (OE HIGH), both Pin compatible with CY62127BV byte high enable and byte low enable are disabled (BHE, BLE HIGH) or during a write operation (CE LOW and WE LOW). Ultra-low active power Writing to the device is accomplished by taking chip enable (CE) Typical active current: 0.85 mA at f = 1 MHz and write enable (WE) inputs LOW. If byte low enable (BLE) is Typical active current: 5 mA at f = f MAX LOW, then data from I/O pins (I/O through I/O ), is written into 0 7 Ultra-low standby power the location specified on the address pins (A through A ). If 0 15 byte high enable (BHE) is LOW, then data from I/O pins (I/O 8 Easy memory expansion with CE and OE features through I/O ) is written into the location specified on the address 15 pins (A through A ). Automatic power-down when deselected 0 15 Reading from the device is accomplished by taking Available in Pb-free 48-ball FBGA and 44-pin TSOP Type II chip enable (CE) and output enable (OE) LOW while forcing the packages write enable (WE) HIGH. If byte low enable (BLE) is LOW, then data from the memory location specified by the address pins Functional Description appear on I/O to I/O . If byte high enable (BHE) is LOW, then 0 7 data from memory appear on I/O to I/O . See the truth table at 8 15 The CY62127DV30 is a high-performance CMOS static RAM the back of this datasheet for a complete description of read and organized as 64 K words by 16-bits. This device features write modes. advanced circuit design to provide ultra-low active current.
