CY7C1019B/

CY7C10191B

128K x 8 Static RAM

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 speci-

fied on the address pins (A₀through A₁₆).

Features

• High speed

— t_AA= 10, 12, 15 ns

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.

• 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

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).

Functional Description

The CY7C1019B/10191B 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.

The CY7C1019B/10191B is available in standard 32-pin

TSOP Type II and 400-mil-wide SOJ packages. Customers

should use part number CY7C10191B when ordering parts

with 10 ns t_AA, and CY7C1019B when ordering 12 and 15 ns

t_AA
