709079L12PFI

Memory IC Overview

The IDT709079L12PFI is a 32K x 8-bit synchronous dual-port static RAM manufactured by Renesas Electronics Corporation. It features true dual-ported memory cells allowing simultaneous access to the same location from both ports. The device operates on a single 5V (±10%) power supply and supports full synchronous operation with registered inputs for minimal setup and hold times. It offers flow-through or pipelined output modes selectable via the FT/PIPE pin, along with counter enable and reset features for burst data applications.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous read/write access to identical addresses from independent ports
• Full synchronous operation on both ports with registered address, data, and control inputs
• Selectable flow-through or pipelined output modes controlled by the FT/PIPE pin
• Automatic low-power standby mode activated by specific chip enable configurations

Memory IC Applications

• High-speed unidirectional or bidirectional data flow in burst applications
• Systems requiring depth expansion without additional logic using dual chip enables
• Interleaved memory applications utilizing counter enable and reset features

Memory IC Procurement Notes

Verify the component status as obsolete when sourcing this part. Confirm that the 'I' suffix denotes the industrial temperature range (-40°C to +85°C) and the 'F8' suffix indicates tape and reel packaging. Ensure compatibility with the 5V TTL-compatible interface requirements before integration into existing designs.

Memory IC Selection Notes

Select this component for applications requiring high-speed synchronous dual-port memory with a 32K x 8 organization. Choose the L variant for lower power consumption compared to the S variant. Verify that the 12ns speed grade meets the system timing requirements for commercial or industrial environments. Ensure the design accommodates the 100-pin TQFP package dimensions.

Memory IC Part Context

This device belongs to the IDT709089/79 family of high-speed synchronous dual-port SRAMs. While originally developed by Integrated Device Technology, Inc., the product line is now managed by Renesas Electronics Corporation. The 709079 specifically provides 256Kb capacity, distinguishing it from the 512Kb 709089 model within the same functional family.
