描述 Description

The IDT70V16/5 is a high-speed 16/8K x 9 Dual-Port Static RAM. The IDT70V16/5 is designed to be used as stand-alone Dual-Port RAMs or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more wider 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.

◆ True Dual-Ported memory cells which allow simultaneous reads of the same memory location

◆ High-speed access

– Commercial:15/20/25ns (max.)

– Industrial: 20ns (max.)

◆ Low-power operation

– IDT70V16/5S

Active: 430mW (typ.)

Standby: 3.3mW (typ.)

– IDT70V16/5L

Active: 415mW (typ.)

Standby: 660µW (typ.)

◆ IDT70V16/5 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 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

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

◆ Available in 68-pin PLCC and an 80-pin TQFP

◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds
