Functional Description
The CY7C1021BN is a high performance CMOS static RAM
organized as 65,536 words by 16 bits. This device has an
automatic power down feature that significantly reduces power
consumption when deselected.
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 the input/output (I/O) pins (I/O1 through
I/O8), is written into the location specified on the address pins (A0
through A15). If Byte High Enable (BHE) is LOW, then data from
I/O pins (I/O9 through I/O16) is written into the location specified
on the address pins (A0 through A15).
Reading from the device is accomplished by taking CE and
Output Enable (OE) LOW while forcing WE HIGH. If BLE is LOW,
then data from the memory location specified by the address pins
appears on I/O1 to I/O8. If BHE is LOW, then data from memory
appears on I/O9 to I/O16. See the Truth Table on page 11 for a
complete description of read and write modes.
The I/O pins (I/O1 through I/O16) 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, WE LOW).
The CY7C1021BN is available in standard 44-pin TSOP type II
and 44-pin 400-mil-wide SOJ packages. Use part number
CY7C1021BN when ordering 15 ns tAA.
