Reading from the device is accomplished by taking Chip En-  
able (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/O to I/O . If Byte High Enable (BHE) is LOW,

— 1430 mW (max.)

HIGH), the outputs are disabled (OE HIGH), the BHE and BLE  
are disabled (BHE, BLE HIGH), or during a write operation (CE  
LOW, and WE LOW).  
Functional Description  
The CY7C1041 is a high-performance CMOS static RAM or-  
ganized as 262,144 words by 16 bits.  
The CY7C1041 is available in a standard 44-pin 400-mil-wide  
body width SOJ and 44-pin TSOP II package with center pow-  
er and ground (revolutionary) pinout.  
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/O through I/O ), is  
0
