RAM Array

• Low operating power

• Fully synchronous interface for easier operation

• Burst counters increment addresses internally

• Dual Chip Enables for easy depth expansion

• Upper and Lower Byte Controls for Bus Matching

• Automatic power-down

• Commercial and Industrial temperature ranges

• Available in 100-pin TQFP

• Pin-compatible and functionally equivalent to

IDT709269, IDT70927, and IDT709279

— Active= 195 mA (typical)

— Standby= 0.05 mA (typical)

— Shorten cycle times

— Minimize bus noise

— Supported in Flow-Through and Pipelined modes
