709289L12PFI8

Memory IC Overview

The Renesas Electronics Corporation 709289L12PFI8 is a high-speed 64K x 16 bit synchronous Dual-Port Static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location from both ports. The device supports flow-through or pipelined output modes selectable via FT/PIPE pins and includes counter enable and reset features for address generation. It operates on a single 5V (±10%) TTL-compatible power supply with automatic power-down capabilities controlled by chip enables.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations from both ports
• Configurable flow-through or pipelined output modes selectable via dedicated control pins
• Integrated address counter with enable and reset functions for automated sequential addressing
• Dual chip enable inputs facilitating depth expansion configurations without external logic

Memory IC Applications

• High-speed burst data transfer applications requiring unidirectional or bidirectional flow
• Systems utilizing multiplexed buses requiring separate upper-byte and lower-byte controls
• Depth expansion memory architectures using multiple synchronized devices
• Applications demanding low standby power through automatic circuitry power-down

Memory IC Procurement Notes

Verify component authenticity as this part originates from Integrated Device Technology, now part of Renesas Electronics. Confirm package integrity for the 100-pin TQFP configuration. Check moisture sensitivity level requirements prior to soldering. Ensure voltage supply matches the specified 5V range. Review datasheet for specific speed grade compatibility with system timing constraints.

Memory IC Selection Notes

Select this component when simultaneous dual-port access is required for high-speed data buffering. Choose the pipelined mode for maximum throughput in burst applications. Verify that the 100-pin TQFP package fits the board layout constraints. Ensure the system operates within the commercial temperature range if selecting the standard grade. Confirm power supply stability within the 5V tolerance limits.

Memory IC Part Context

This device belongs to the IDT709289L family of synchronous dual-port SRAMs. It shares architectural similarities with other members like the 709289L7 and 709289L9, differing primarily in access speed grades. The family utilizes CMOS high-performance technology optimized for low power consumption while maintaining high-speed operation suitable for complex digital systems.

Memory IC Replacement Considerations

Compatible substitutes include the IDT709289L7PF8 and IDT709289L9PF8. These variants offer faster access times but maintain identical pinouts and functionality. Verify that the replacement speed grade meets or exceeds the original design requirements. Ensure the package type remains consistent for direct board replacement.
