IDT7024L55J Datasheet



The IDT7024L55J is a high-speed 4Kx 16 Dual-Port Static RAM. The IDT7024 is designed to be used as a stand-alone 64K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.The IDT7024 is packaged in a ceramic 84-pin PGA, an 84-pin Flatpack and PLCC, and a 100-pin TQFP. Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML, making it ideally suited to military temperature applications demanding the highest level of performance and reliability. IDT7024L55J Features • True Dual-Ported memory cells which allow simultaneous reads of the same memory location• High-speed access Military: 20/25/35/55/70ns (max.) Industrial: 55ns (max.) Commercial: 15/17/20/25/35/55ns (max.)• Separate upper-byte and lower-byte control for multiplexed bus compatibility• IDT7024 easily expands data bus width to 32 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• Battery backup operation—2V data retention• TTL-compatible, single 5V (±10%) power supply• Available in 84-pin PGA, Flatpack, PLCC, and 100-pin Thin Quad Flatpack• Industrial temperature range (–40°C to +85°C) is available for selected speeds• Green parts availble, see ordering information
