CY7C1061AV33
16-Mbit (1 M × 16) Static RAM
Features
Functional Description
■ High speed
❐ tAA = 10 ns
The CY7C1061AV33 is a high performance CMOS Static RAM
organized as 1,048,576 words by 16 bits.
■ Low active power
❐ 990 mW (max)
To write to the device, enable the chip (CE1 LOW and CE2 HIGH)
while forcing the Write Enable (WE) input LOW. If Byte Low
Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7),
is written into the location specified on the address pins (A0
through A19). If Byte High Enable (BHE) is LOW, then data from
I/O pins (I/O8 through I/O15) is written into the location specified
on the address pins (A0 through A19).
■ Operating voltages of 3.3 ± 0.3 V
■ 2.0 V data retention
■ Automatic power down when deselected
■ TTL compatible inputs and outputs
■ Easy memory expansion with CE1 and CE2 features
To read from the device, enable the chip by taking CE1 LOW and
CE2 HIGH while forcing the Output Enable (OE) LOW and 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/O0 to I/O7. If Byte High Enable (BHE) is LOW, then
data from memory will appear on I/O8 to I/O15. See “Truth Table”
on page 8 for a complete description of Read and Write modes.
■ Available in Pb-free and non Pb-free 54-pin TSOP II package
and non Pb-free 60-ball fine pitch ball grid array (FBGA)
package
The input/output pins (I/O0 through I/O15) are placed in a
high-impedance state when the device is deselected (CE1
HIGH/CE2 LOW), the outputs are disabled (OE HIGH), the BHE
and BLE are disabled (BHE, BLE HIGH), or a Write operation is
in progress (CE1 LOW, CE2 HIGH, and WE LOW).
