DESCRIPTION: The IDT7005 is a high-speed 8K x 8 Dual-Port Static RAM. The IDT7005 is designed to be used as a stand-alone Dual Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-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 access of the same memory location • High-speed access — Military: 20/25/35/55/70ns (max.) — Commercial:15/17/20/25/35/55ns (max.) • Low-power operation — IDT7005S Active: 750mW (typ.) Standby: 5mW (typ.) — IDT7005L Active: 750mW (typ.) Standby: 1mW (typ.) • IDT7005 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 BUSYoutput flag on Master, M/S= L for BUSYinput on Slave • Busy and Interrupt Flags • On-chip port arbitration logic • Full on-chip hardware support of Semaphore signaling between ports • Fully asynchronous operation from either port • Devices are capable of withstanding greater than 2001V electrostatic discharge • Battery backup operation—2V data retention • TTL-compatible, single 5V (±10%) power supply • Available in 68-pin PGA, 68-pin quad flatpack, 68-pin PLCC, and a 64-pin TQFP • Industrial temperature range (–40°C to +85°C) is available, tested to military electrical specifications
