Description
The IDT7008 is a high-speed 64K x 8 Dual-Port Static RAM. The IDT7008 is designed to be used as a stand-alone 512K-bit 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.

◆ Dual chip enables allow for depth expansion without external logic
◆ IDT7008 easily expands data bus width to 16 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
◆ 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 84-pin PGA, 84-pin PLCC, and a 100-pin TQFP
◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds
◆ Green parts available, see ordering information
