CY7C109D-10ZXI Datasheet PDF - Cypress Semiconductor

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)

●Features

●• 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
