709079L15PF8

Memory IC Overview

The Renesas Electronics Corporation 709079L15PF8 is a high-speed 256Kb (32K x 8) synchronous dual-port static RAM. It operates on a single 5V power supply and supports commercial temperature ranges from 0°C to +70°C. The device features true dual-ported memory cells allowing simultaneous access to the same location. It offers a maximum clock-to-data access time of 15ns in flow-through mode or 15ns cycle time in pipelined mode. The component is housed in a 100-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to any address from both ports
• Full synchronous operation with registered inputs for minimal setup and hold times
• Configurable output modes selectable via FT/PIPE pin for either flow-through or pipelined data delivery
• Dual chip enables facilitating depth expansion without additional external logic

Memory IC Applications

• High-speed data buffering in network communication systems
• FIFO buffer implementations requiring concurrent read/write operations
• Cache memory applications in embedded processing architectures
• Data acquisition systems utilizing burst transfer capabilities

Memory IC Procurement Notes

Verify the specific suffix PF8 corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the L designation aligns with low-power specifications if active power consumption is a critical design constraint. Ensure the manufacturer documentation explicitly lists this part number as available, noting potential obsolescence status associated with legacy IDT product lines acquired by Renesas.

Memory IC Selection Notes

Select this component when a system requires fully synchronous dual-port SRAM with a 32K x 8 organization. It is suitable for designs needing a single 5V supply and operating within commercial temperature limits. Consider the 100-pin TQFP footprint for PCB layout constraints. Evaluate whether the 15ns speed grade meets the timing requirements compared to faster 9ns or 12ns variants available in the series.

Memory IC Part Context

This device belongs to the IDT 709089/79 family of high-speed synchronous dual-port static random-access memories. Originally manufactured by Integrated Device Technology, Inc., the product line was integrated into Renesas Electronics following corporate acquisitions. The 709079 variant specifically denotes the 256Kb density version of the broader family.
