com can be put into standby mode when deselected (CE HIGH or both BHE and BLE are HIGH).
The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when the chip is deselected (CE HIGH), or when the outputs are disabled (OE HIGH), or when 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 asserting Chip Enable (CE LOW) and Write Enable (WE) input 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 A17).
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 asserting Chip Enable (CE LOW) 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.
Refer to the truth table for a complete description of read and write modes.
• Automatic power-down when deselected • CMOS for optimum speed/power • Offered in a 48-ball BGA Package Functional Description[1] The CYK128K16MCCB is a high-performance CMOS Pseudo Static RAM organized as 128K words by 16 bits that supports an asynchronous memory interface.
