4Kx4 RAM

Features

Functional Description

The CY7C168A is a high-performance CMOS static RAM or-

ganized as 4096 by 4 bits. Easy memory expansion is provid-

ed by an active LOW Chip Enable (CE) and three-state driv-

ers. The CY7C168A has an automatic power-down feature,

reducing the power consumption by 77% when deselected.

• Automatic power-down when deselected

• CMOS for optimum speed/power

• High speed

— t_AA= 15 ns

• Low active power

Writing to the device is accomplished when the Chip Select

(CE) and Write Enable (WE) inputs are both LOW. Data on the

four data input/output pins (I/O₀through I/O₃) is written into the

memory location specified on the address pins (A₀through

A₁₁).

— 633 mW

• Low standby power

— 110 mW

• TTL-compatible inputs and outputs

• V_IHof 2.2V

• Capable of withstanding greater than 2001V electro-

static discharge

Reading the device is accomplished by taking the Chip Enable

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

these conditions, the contents of the location specified on the

address pins will appear on the four data input/output pins

(I/O₀through I/O₃).

The input/output pins remain in a high-impedance state when

Chip Enable (CE) is HIGH or Write Enable (WE) is LOW.

A die coat is used to insure alpha immunity.
