cy62126esl mobl®1 - Mbit（64 K×16）静态RAM
分享资料个
The CY62126ESL is a high performance CMOS static RAM organized as 64K 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. The device also has an automatic power down feature that significantly reduces power consumption when addresses are not toggling. Placing the device into standby mode reduces power consumption by more than 99 percent when deselected （CE HIGH）。 The input and output pins （I/O0 through I/O15） are placed in a high impedance state when the device is deselected （CE HIGH）， the 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）。 To write to the device， take 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 A15）。 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 A15）。 To read from the device， take 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 appear on I/O0 to I/O7. If Byte High Enable （BHE） is LOW， then data from memory appears on I/O8 to I/O15. See the Truth Table on page 11 for a complete description of read and write modes. The CY62126ESL device is suitable for interfacing with processors that have TTL I/P levels. It is not suitable for processors that require CMOS I/P levels.
