IDT7015S/L

HIGH-SPEED

8K x 9 DUAL-PORT

STATIC RAM

Features:

◆

M/S = VIH for BUSY output flag on Master

M/S = VIL for BUSY input on Slave

Busy and Interrupt Flag

On-chip port arbitration logic

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 ceramic 68-pin PGA, 68-pin PLCC, and an 80-

pin TQFP

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

for selected speeds

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

◆

– Commercial:12/15/17/20/25/35ns(max.)

– Industrial: 20ns (max.)

– Military:20/25/35ns(max.)

Low-power operation

◆

– IDT7015S

Active:750mW(typ.)

Standby: 5mW (typ.)

– IDT7015L

◆

Active:750mW(typ.)

Standby: 1mW (typ.)

Green parts available, see ordering information

◆

IDT7015 easily expands data bus width to 18 bits or more

using the Master/Slave select when cascading more than

one device

NOTES:

1. In MASTER mode: BUSY is an output and is a push-pull driver

In SLAVE mode: BUSY is input.

2. BUSY outputs and INT outputs are non-tri-stated push-pull drivers.
