CY7C109D-10ZXI概述

CY7C109D 系列 1 Mb 128 K x 8 5 V 10 ns 静态 RAM - TSOP-32

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
