CY7C1007

1M x 1 Static RAM

memory expansion is provided by an active LOW Chip Enable

(CE) and three-state drivers. These devices have an automatic

power-down feature that reduces power consumption by more

than 65% when deselected.

Features

• High speed

— t = 12 ns

Writing to the devices is accomplished by taking Chip Enable

(CE) and Write Enable (WE) inputs LOW. Data on the input pin

• CMOS for optimum speed/power

• Low active power

— 825 mW

(D ) is written into the memory location specified on the ad-

dress pins (A through A ).

• Low standby power

— 275 mW

Reading from the devices is accomplished by taking Chip En-

able (CE) LOW while Write Enable (WE) remains HIGH. Under

these conditions, the contents of the memory location speci-

• 2.0V data retention (optional)

fied by the address pins will appear on the data output (D

pin.

• Automatic power-down when deselected

• TTL-compatible inputs and outputs

The output pin (D

) is placed in a high-impedance state

OUT

when the device is deselected (CE HIGH) or during a write

operation (CE and WE LOW).

Functional Description

The CY7C107 and CY7C1007 are high-performance CMOS

static RAMs organized as 1,048,576 words by 1 bit. Easy

The CY7C107 is available in a standard 400-mil-wide SOJ; the

CY7C1007 is available in a standard 300-mil-wide SOJ.
