Description
The IDT70261 is a high-speed 16K x 16 Dual-Port Static RAM. The IDT70261 is designed to be used as a stand-alone 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
◆ IDT70261 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
◆ 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
◆ TTL-compatible, single 5V (±10%) power supply
◆ Available in 100-pin Thin Quad Flatpack
◆ Industrial temperature range (-40OC to +85OC) is available for selected speeds
