Features
Functional Description
The CY7C1041BV33 is a high-performance CMOS Static
RAM organized as 262,144 words by 16 bits.
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

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/O
LOW, then data from memory will appear on I/O

description of read and write modes.
The input/output pins (I/O

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).
The CY7C1041BV33 is available in a standard 44-pin
400-mil-wide body width SOJ and 44-pin TSOP II package
with center power and ground (revolutionary) pinout.
