709079S15PF

Memory IC Overview

The Renesas Electronics Corporation 709079S15PF is a high-speed 32K x 8-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 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 registered inputs.

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 dedicated control pins
• 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 network communication systems
• Cache memory implementations in embedded processing architectures
• FIFO buffer applications requiring unidirectional or bidirectional data flow bursts
• Real-time signal processing systems needing low-latency memory access

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper handling procedures are followed due to humidity sensitivity requirements specified in the datasheet. Cross-reference ordering suffixes carefully to match required speed grades and temperature ranges.

Memory IC Selection Notes

Select this component when simultaneous read/write access to shared memory locations is required. Choose between flow-through and pipelined modes based on system latency constraints. Verify that the 5V TTL-compatible interface matches the host controller voltage levels. Consider the industrial temperature range availability if operating conditions exceed commercial limits.

Memory IC Part Context

This device belongs to the IDT709089/79 family of synchronous dual-port SRAMs manufactured by Integrated Device Technology, now part of Renesas Electronics. The 709079 variant specifically provides 256Kbit capacity organized as 32K words by 8 bits. It shares architectural similarities with the 64Kx8 709089 model but offers reduced density suitable for specific memory footprint requirements.

Memory IC Replacement Considerations

IDT709079L15PFI serves as a compatible alternative offering industrial temperature range specifications while maintaining identical functional characteristics and pinout compatibility.
