CY7C1009D

1-Mbit (128 K × 8) Static RAM

Features

Functional Description ^[1]

■ Pin- and function-compatible with CY7C109B/CY7C1009B

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 (I/O₀through I/O₇) are placed in a high-impedance

state when:

■ High speed

❐ t_AA= 10 ns

■ Low active power

❐ I_CC= 80 mA at 10 ns

■ Low CMOS standby power

❐ I_SB2= 3 mA

■ Deselected (CE₁HIGH or CE₂LOW),

■ Outputs are disabled (OE HIGH),

■ 2.0 V Data Retention

■ Automatic power-down when deselected

■ TTL-compatible inputs and outputs

■ Easy memory expansion with CE₁, CE₂and OE options

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

and WE LOW)

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 I/O pins (I/O₀through I/O₇) is then

written into the location specified on the address pins (A₀

through A₁₆).

■ CY7C109D available in Pb-free 32-pin 400-Mil wide Molded

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 I/O pins.
