CY7C1009D

1-Mbit (128K x 8) Static RAM

Features

Functional Description ^[1]

• Pin- and function-compatible with CY7C109B/CY7C1009B

• High speed

The CY7C109D/CY7C1009D 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

(CE₁), an active HIGH Chip Enable (CE₂), an active LOW

Output Enable (OE), and tri-state drivers.The eight input and

output pins (IO₀through IO₇) are placed in a high-impedance

state when:

— t_AA= 10 ns

• Low active power

— I_CC= 80 mA @ 10 ns

• Low CMOS standby power

— I_SB2= 3 mA

• Deselected (CE₁HIGH or CE₂LOW),

• Outputs are disabled (OE HIGH),

• 2.0V Data Retention

• When the write operation is active (CE₁LOW, CE₂HIGH,

and WE LOW)

• Automatic power-down when deselected

• TTL-compatible inputs and outputs

• Easy memory expansion with CE₁, CE₂and OE options

Write to the device by taking Chip Enable One (CE₁) and Write

Enable (WE) inputs LOW and Chip Enable Two (CE₂) input

HIGH. Data on the eight IO pins (IO₀through IO₇) is then

written into the location specified on the address pins (A₀

through A₁₆).

• CY7C109DavailableinPb-free32-pin400-MilwideMolded

SOJ and 32-pin TSOP I packages. CY7C1009D available

in Pb-free 32-pin 300-Mil wide Molded SOJ package

Read from the device by taking Chip Enable One (CE₁) and

Output Enable (OE) LOW while forcing Write Enable (WE) and

Chip Enable Two (CE₂) HIGH. Under these conditions, the

contents of the memory location specified by the address pins

appears on the IO pins.
