709079L9PF8

Memory IC Overview

The Renesas Electronics Corporation 709079L9PF8 is a high-speed 256Kb (32K x 8) synchronous dual-port static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location from both ports. The device operates on a single 5V power supply and supports flow-through or pipelined output modes via the FT/PIPE pin. It includes counter enable and reset features, dual chip enables for depth expansion, and full synchronous operation on both ports with minimal setup and hold times.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to any address from both ports
• Configurable flow-through or pipelined output modes selectable via the FT/PIPE control pin
• Integrated address counter with enable and reset capabilities for sequential burst operations
• Dual chip enable inputs facilitating depth expansion without requiring additional external logic

Memory IC Applications

• High-speed data buffering in unidirectional or bidirectional burst data flows
• Interfacing between asynchronous systems requiring registered input/output timing
• Depth expansion configurations utilizing multiple chips controlled by dual chip enables
• Applications requiring simultaneous read/write access to shared memory locations

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm package integrity upon receipt, specifically checking for damage to the 100-pin TQFP leads. Ensure proper ESD handling protocols are followed during storage and installation. Cross-reference ordering suffixes carefully to match required speed grades and temperature ranges. Check for RoHS compliance status if environmental regulations apply to the end application.

Memory IC Selection Notes

Select this component when simultaneous dual-port access is required for shared memory applications. Choose the pipelined mode for higher throughput requirements or flow-through for lower latency needs. Ensure the system design accommodates the 5V TTL-compatible logic levels. Verify that the operating temperature range meets the specific commercial or industrial requirements of the target environment.

Memory IC Part Context

This device belongs to the IDT 709089/79 family of synchronous dual-port SRAMs. It shares architectural similarities with the 709089 but offers a reduced density of 32K x 8 bits compared to the 64K x 8 variant. The technology utilizes CMOS processes optimized for low power consumption while maintaining high-speed performance characteristics suitable for complex digital signal processing tasks.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT709079L9PFGI and IDT709079L9PFI. Verify compatibility regarding package dimensions and pinout assignments before substitution. Ensure electrical specifications such as voltage levels and timing parameters align with the existing system design constraints.
