CY7C1009D-10 Datasheet

1-Mbit (128K x 8) Static RAM


Functional Description
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 (IO0 through IO7) are placed in a high-impedance state when:
• Deselected (CE1 HIGH or CE2 LOW),
• Outputs are disabled (OE HIGH),
• When the write operation is active (CE1 LOW, CE2 HIGH, and WE LOW)

• Pin- and function-compatible with CY7C109B/CY7C1009B
• High speed
— tAA = 10 ns
• Low active power
— ICC = 80 mA @ 10 ns
• Low CMOS standby power
— ISB2 = 3 mA
• 2.0V Data Retention
• Automatic power-down when deselected
• TTL-compatible inputs and outputs
• Easy memory expansion with CE1, CE2 and OE options
• 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
