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 64K-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.

Features

◆ 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 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
◆ 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, PLCC and a 64-pin thin quad flatpack
◆ Industrial temperature range (-40°C to +85°C) is available for selected speeds
