709279L9PFG

Memory IC Overview

The Renesas Electronics Corporation 709279L9PFG is a high-speed 32K x 16 bit synchronous Dual-Port Static Random Access Memory (SRAM). It features a parallel interface with a maximum access time of 9 ns. The device operates on a single 5V power supply, with voltage specifications ranging from 4.5 V to 5.5 V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) suitable for surface mount installation. The component supports an operating temperature range from 0°C to +70°C and includes automatic power-down capabilities controlled by chip enables.

Memory IC Feature Summary

• Dual-port architecture allows simultaneous independent access to the same memory location by two separate ports.
• Supports both flow-through and pipelined output modes selectable via the FT/PIPE pin for optimized data flow.
• Includes counter enable and reset features along with dual chip enables for depth expansion without additional logic.

Memory IC Applications

• Applications requiring unidirectional or bidirectional data flow in bursts
• Systems utilizing multiplexed buses requiring upper-byte and lower-byte controls
• High-speed data buffering where simultaneous port access is necessary

Memory IC Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as L9PF8 or L9PFI indicate different packaging types like tape-and-reel versus tray. Confirm RoHS compliance status, as specific suffixes may denote non-compliant versions. Check current lifecycle status, as this part number may be obsolete or discontinued. Ensure the selected variant matches the required industrial or commercial temperature grade for the intended environment.

Memory IC Selection Notes

Select this component when a synchronous dual-port SRAM with 512 Kbit density and 9 ns speed is required. Ensure the design accommodates the 100-pin TQFP footprint and 5V logic levels. Consider the pipelined or flow-through mode requirements based on system timing constraints. Verify that the power supply stability meets the 4.5 V to 5.5 V specification to ensure reliable operation within the specified temperature range.
