709289L12PF8

Memory IC Overview

The IDT709289L12PF8 is a high-speed 64K x 16 bit synchronous Dual-Port Static RAM. It features true dual-port memory cells allowing simultaneous access of the same location from both ports. The device supports flow-through or pipelined output modes on either port via dedicated FT/PIPE pins. It includes counter enable and reset features, dual chip enables for depth expansion without additional logic, and separate upper-byte and lower-byte controls. The component operates with a single 5V (±10%) TTL-compatible power supply and is available in a 100-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous access to identical memory locations
• Configurable flow-through or pipelined output modes selectable per port
• Integrated address counter with enable and reset capabilities
• Dual chip enables facilitating depth expansion without external logic

Memory IC Applications

• High-speed communication buffer systems
• Unidirectional or bidirectional data flow burst applications
• Multiplexed bus and bus matching compatibility designs
• Depth expansion configurations requiring multiple synchronized devices

Memory IC Procurement Notes

Verify RoHS compliance status as the specific part number may not meet current environmental directives. Confirm lead time and availability through authorized distributors, noting that this component may be subject to discontinuation notices. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference ordering suffixes carefully to confirm package type and temperature range specifications match design requirements.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. Choose the pipelined mode for higher throughput applications and flow-through for simpler latency requirements. Verify voltage levels align with the 5V ±10% specification. Consider the 100-pin TQFP package constraints for PCB layout. Evaluate power consumption characteristics against system thermal limits during active and standby operations.

Memory IC Part Context

This device belongs to the IDT7092 series of synchronous dual-port SRAMs manufactured by Integrated Device Technology, now part of Renesas Electronics. It is designed for high-performance buffering and data storage in communication systems. The L suffix indicates low-power operation compared to standard variants. The PF8 suffix denotes the 100-pin TQFP package with tape and reel packaging.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements within the IDT709289 family with different speed grades or temperature ranges. Verify functional equivalence if substituting with other synchronous dual-port SRAMs. Review datasheets for timing parameter differences and power consumption variations. Confirm package dimensions and pinout compatibility before implementation.
