HIGH-SPEED

IDT7009L

128K x 8 DUAL-PORT

STATIC RAM

Features

◆

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

M/S = VIL for BUSY input on Slave

Interrupt Flag

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

◆

On-chip port arbitration logic

– Commercial:15/20ns (max.)

Low-power operation

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

TTL-compatible, single 5V (±10%) power supply

Available in a 100-pin TQFP

– IDT7009L

◆

Active:1W(typ.)

Standby: 1mW (typ.)

◆

Dual chip enables allow for depth expansion without

external logic

IDT7009 easily expands data bus width to 16 bits or

more using the Master/Slave select when cascading more

than one device

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

for selected speeds

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).
