Features Functional Description
Temperature ranges The CY7C1041CV33 is a high performance CMOS static RAM
organized as 262,144 words by 16 bits.
Industrial: 40 C to 85 C
To write to the device, take Chip Enable (CE) and Write Enable
Pin and function compatible with CY7C1041BV33
(WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data

To read from the device, take Chip Enable (CE) and Output
Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If
Automatic power down when deselected
Byte Low Enable (BLE) is LOW, then data from the memory
location specified by the address pins appear on I/O to I/O . If
TTL-compatible inputs and outputs

modes.
The input and output pins (I/O through I/O ) are placed in a
0 15
high impedance state when the device is deselected (CE 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).
