CYK256K16MCCB  
MoBL3™  
4-Mbit (256K x 16) Pseudo Static RAM  
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:  
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).  
Features  
• Wide voltage range: 2.70V–3.30V  
• Access time: 55 ns, 60 ns and 70 ns  
• Ultra-low active power  
— Typical active current: 1 mA @ f = 1 MHz  
— Typical active current: 8 mA @ f = fmax (70-ns speed)  
• Ultra low standby power  
Writing to the device is accomplished by taking 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 A17).  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
• Offered in a 48-ball BGA package  
Reading from the device is accomplished by taking 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.  
Functional Description[1]  
The CYK256K16MCCB is a high-performance CMOS Pseudo  
static RAM organized as 256K words by 16 bits that supports  
an asynchronous memory interface. 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
