Features

Functional Description

■ Pin and function compatible with CY7C1049CV33

The CY7C1049DV33 is a high performance CMOS Static RAM

organized as 512K words by 8-bits. Easy memory expansion is

provided by an Active LOW Chip Enable (CE), an Active LOW

Output Enable (OE), and tri-state drivers. You can write to the

device by taking Chip Enable (CE) and Write Enable (WE) inputs

LOW. Data on the eight IO pins (IO₀through IO₇) is then written

into the location specified on the address pins (A₀through A₁₈).

■ High speed

❐ t_AA= 10 ns

■ Low active power

❐ I_CC= 90 mA @ 10 ns (Industrial)

■ Low CMOS standby power

❐ I_SB2= 10 mA

You can read from the device by taking Chip Enable (CE) and

Output Enable (OE) LOW while forcing Write Enable (WE) HIGH.

Under these conditions, the contents of the memory location

specified by the address pins appear on the IO pins.

■ 2.0 V data retention

■ Automatic power down when deselected

■ TTL compatible inputs and outputs

■ Easy memory expansion with CE and OE features

The eight input or output pins (IO₀through IO₇) are placed in a

high impedance state when the device is deselected (CE HIGH),

the outputs are disabled (OE HIGH), or during a write operation

(CE LOW, and WE LOW).

■ Available in Pb-free 36-pin (400 Mil) Molded SOJ and 44-pin

TSOP II packages

The CY7C1049DV33 is available in standard 400 Mil wide 36

-pin SOJ package and 44-pin TSOP II package with center

power and ground (revolutionary) pinout.
