CY7C1019BN

128K x 8 Static RAM

Features

Functional Description

• High speed

The CY7C1019BN is a high-performance CMOS static RAM

organized as 131,072 words by 8 bits. Easy memory

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

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

device has an automatic power-down feature that significantly

reduces power consumption when deselected.

— t_AA= 12, 15 ns

• CMOS for optimum speed/power

• Center power/ground pinout

• Automatic power-down when deselected

• Easy memory expansion with CE and OE options

• Functionally equivalent to CY7C1019

Writing to the device is accomplished by taking Chip Enable

(CE) and Write Enable (WE) inputs LOW. Data on the eight I/O

pins (I/O₀through I/O₇) is then written into the location

specified on the address pins (A₀through A₁₆).

Reading from the device is accomplished 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 will appear

on the I/O pins.

The eight input/output pins (I/O₀through I/O₇) 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).

The CY7C1019BN is available in standard 32-pin TSOP Type

II and 400-mil-wide SOJ packages.
