HIGH-SPEED 3.3V

128K x 9 DUAL-PORT

STATIC RAM

IDT70V19L

Features

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed access

M/S = VIH for BUSY output flag on Master,

M/S = VIL 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

◆

– Commercial:15/20ns (max.)

– Industrial:20ns (max.)

Low-power operation

◆

– IDT70V19L

Active: 440mW (typ.)

Standby: 660µW (typ.)

Dual chip enables allow for depth expansion without

external logic

IDT70V19 easily expands data bus width to 18 bits or

more using the Master/Slave select when cascading more

than one device

NOTES:

1. BUSY is an input as a Slave (M/S=V^IL) and an output when it is a Master (M/S=VIH).

2. BUSY and INT are non-tri-state totem-pole outputs (push-pull).
