CY7C1041CV33
4-Mbit (256K x 16) Static RAM
Features
Functional Description
The CY7C1041CV33 is a high performance CMOS static RAM
organized as 262,144 words by 16 bits.
To write to the device, take Chip Enable (CE) and Write Enable
(WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data
from IO pins (IO
0
through IO
7
), is written into the location
specified on the address pins (A
0
through A
17
). If Byte High
Enable (BHE) is LOW, then data from IO pins (IO
8
through IO
15
)
is written into the location specified on the address pins (A
0
through A
17
).
To read from the device, take 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 appear on IO
0
to IO
7
. If
Byte High Enable (BHE) is LOW, then data from memory
appears on IO
8
to IO
15
. For more information, see the
Truth
Table
on page 9 for a complete description of Read and Write
modes.
The input and output pins (IO
0
through IO
15
) are placed in a 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).
For best practice recommendations, refer to the Cypress
application note
AN1064, SRAM System Guidelines.
