HIGH-SPEED 3.3V

128K x 8 DUAL-PORT

STATIC RAM

Features

IDT70V09L

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed access

– Commercial: 15/20ns (max.)

– Industrial: 20ns (max.)

Low-power operation

– IDT70V09L

Active: 440mW (typ.)

Standby: 660µW (typ.)

Dual chip enables allow for depth expansion without

external logic

IDT70V09 easily expands data bus width to 16 bits or

more using the Master/Slave select when cascading more

than one device

◆

M/S = V

for

BUSY

input on Slave

Busy and Interrupt Flags

On-chip port arbitration logic

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

LVTTL-compatible, single 3.3V (±0.3V) power supply

Available in a 100-pin TQFP

Industrial temperature range (–40°C to +85°C) is available

for selected speeds

Green parts available, see ordering information
