CY7C1046BN

1M x 4 Static RAM

You write to the device by taking Chip Enable (CE) and Write

Enable (WE) inputs LOW. Data on the four IO pins (IO₀

Features

• Low active power

through IO₃) is then written into the location specified on the

address pins (A₀through A₁₉).

— 825 mW (max)

• Low CMOS standby power

You 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 appears on the IO pins.

— 44 mW (max)

• 2.0V data retention (400 μW at 2.0V retention)

• Automatic power down when deselected

• TTL-compatible inputs and outputs

• Easy memory expansion with CE and OE features

• Available in non Pb-free 400 mil wide 32-pin SOJ package

The four input and output pins (IO₀through IO₃) are placed in

a high impedance state when the device is deselected (CE

HIGH), the outputs are disabled (OE HIGH), or when the write

operation is active (CE LOW, and WE LOW).

Functional Description

The CY7C1046BN is available in a standard 400-mil-wide

32-pin SOJ package with center power and ground (revolu-

tionary) pinout.

The CY7C1046BN is a high performance CMOS static RAM

organized as 1,048,576 words by 4 bits. Easy memory

expansion is provided by an active LOW Chip Enable (CE), an

active LOW Output Enable (OE), and tri-state drivers.
