CY62137VLL-70ZE Description

The CY62137V is a high-performance CMOS static RAM organized as 128K words by 16 bits. This device features advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery Life? (MoBL®) in portable applications such as cellular telephones. The device also has an automatic power-down feature that reduces power consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected (/CE HIGH) or when /CE is LOW and 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), /BHE and /BLE 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 will appear on I/O0 to I/O7. If Byte High Enable (/BHE) is LOW, then data from memory will appear on I/O8 to I/O15. See the truth table at the back of this data sheet for a complete description of read and write modes.
