DESCRIPTION:
The IDT71321/IDT71421 are high-speed 2K x 8 Dual Port Static RAMs with internal interrupt logic for interprocessor communications. The IDT71321 is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a MASTER Dual-Port RAM together with the IDT71421 SLAVE Dual Port in 16-bit-or-more word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-or-more bit memory system applications results in full speed, error free operation without the need for additional discrete logic.
FEATURES:
• High-speed access
—Commercial: 20/25/35/45/55ns (max.)
• Low-power operation
—IDT71321/IDT71421SA
—Active: 550mW (typ.)
—Standby: 5mW (typ.)
—IDT71321/421LA
—Active: 550mW (typ.)
—Standby: 1mW (typ.)
• Two INT flags for port-to-port communications
• MASTER IDT71321 easily expands data bus width to 16-or-more-bits using SLAVE IDT71421
• On-chip port arbitration logic (IDT71321 only)
• BUSY output flag on IDT71321; BUSY input on IDT71421
• Fully asynchronous operation from either port
• Battery backup operation —2V data retention (LA Only)
• TTL-compatible, single 5V ±10 power supply
• Available in popular hermetic and plastic packages
• Industrial temperature range (–40°C to +85°C) is available, tested to military electrical specifications
