The IDT71321SA35J is a high-speed 2K x 8 Dual-Port Static RAM (SRAM) device manufactured by Integrated Device Technology (IDT). This device provides asynchronous, simultaneous access to a common memory array from two independent ports. The integrated arbitration logic manages potential conflicts when both ports attempt to access the same memory location.

Applications

• Shared memory systems
• Multiprocessor systems
• Network buffer memory
• Industrial automation
• High-speed data acquisition

Features

• True Dual-Ported memory cells allow simultaneous access
• Fast access time: 35ns
• On-chip arbitration logic
• Independent port control
• Low operating power
• Interrupt flags for inter-processor communication

Benefits

• Enables efficient data sharing between processors
• Reduces system latency
• Simplifies system design
• Improves overall system performance
• Reduces power consumption

Additional Details

The IDT71321SA35J requires a single 5V power supply and offers independent control signals for each port, allowing for asynchronous read and write operations. The on-chip arbitration logic prevents data corruption when both ports attempt to access the same memory location. The interrupt flags provide a mechanism for signaling between processors.

Specific technical details include typical operating current of approximately 150mA and a standby current of under 30mA. Please consult the IDT datasheet for detailed timing diagrams, voltage levels, and other pertinent specifications.
