Features

True Dual-Ported memory cells which allow simultaneous reads of the same memory location High-speed access ­ Military: 25/35/55ns (max.) ­ Industrial: 20/25/35/55ns (max.) ­ Commercial: 15/20/25/35/55ns (max.) Low-power operation ­ IDT7007S Active: 850mW (typ.) Standby: 5mW (typ.) ­ IDT7007L Active: 850mW (typ.) Standby: 1mW (typ.) IDT7007 easily expands data bus width to 16 bits or more

using the Master/Slave select when cascading more than one device M/S = H for BUSY output flag on Master, M/S = L for BUSY input on Slave 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 68-pin PGA and PLCC and a 80-pin TQFP Industrial temperature range +85°C) is available for selected speeds Green parts available, see ordering information

NOTES: 1. (MASTER): BUSY is output; (SLAVE): BUSY is input. 2. BUSY and INT outputs are non-tri-stated push-pull.

Description

The is a high-speed x 8 Dual-Port Static RAM. The IDT7007 is designed to be used as a stand-alone 256K-bit Dual-Port RAM as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach 16-bit or wider memory system applications results in full-speed, errorfree operation without the need for additional discrete logic. This device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down

feature controlled by CE permits the on-chip circuitry of each port to enter a very LOW standby power mode. Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 850mW of power. The IDT7007 is packaged a 68-pin pin PGA, a 68-pin PLCC, and an 80-pin thin quad flatpack, TQFP. Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
