CY62137CV18

CY62137CV18 MoBL2™ 128K x 16 Static RAM Features High Speed — 55 ns and 70 ns availability Low voltage range: — CY62137CV18: 1.65V−1.95V Pin Compatible w/ CY62137V18/BV18 Ultra-low active power — Typical Active Current: 0.5 mA @ f = 1 MHz — Typical Active Current: 1.5 mA @ f = fmax (70 ns speed) Low standby power Easy memory expansion with CE and OE features Automatic power-down when deselected CMOS for optimum speed/power power consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected (CE HIGH or both BLE and BHE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE LOW, and WE LOW). Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7), is written into the location specified on the address pins (A0 through A16). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A16). Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins...
