Description:

The IDT7015 is a high-speed 8K x 9 Dual-Port Static RAM. The IDT7015 is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

Features:

◆ 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.)

◆ IDT7015 easily expands data bus width to 18 bits or more using the Master/Slave select when cascading more than one device

◆ M/S = VIH for BUSY output flag on aster

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

◆ Green parts available, see ordering information
