Description
The IDT7024 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.

Features

◆ 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 BUSYoutput flag on Master
    M/S= L for BUSYinput 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
