709279S15PF8

Memory IC Overview

The Renesas Electronics Corporation 709279S15PF8 is a high-speed synchronous dual-port static random-access memory (SRAM) IC. It features a storage capacity of 512 kilobits, organized as 32K words by 16 bits. The device utilizes a parallel interface and supports simultaneous independent access to the same memory location from two separate ports. It operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It offers an access time of 15 nanoseconds and is rated for an industrial operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous read/write operations from both ports without conflict.
• Full synchronous operation on both ports with flow-through or pipelined output modes selectable via external pin.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Automatic power-down feature controlled by chip enables to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring burst data handling.
• Master/Slave dual-port configurations in multi-processor systems for error-free communication.
• Industrial control systems needing reliable real-time data exchange between processing units.
• Network switches and routers utilizing bidirectional data flow optimization.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for end-of-life notifications or obsolescence notices from Renesas. Ensure proper ESD handling during installation. Validate package markings against official datasheet specifications to avoid substitution errors.

Memory IC Selection Notes

Select this component when synchronous dual-port SRAM functionality is required for high-speed data transfer applications. Consider the 15ns access time and 100-pin TQFP package constraints for PCB layout. Evaluate power consumption requirements given the automatic power-down capabilities. Compare with asynchronous alternatives if clock synchronization is not feasible in the design. Verify temperature range suitability for the intended operational environment.

Memory IC Part Context

The 709279 series belongs to Renesas' family of high-speed synchronous dual-port RAMs. These devices are designed for applications demanding high bandwidth and low latency. The series includes variants with different access times and temperature grades. The 709279S15PF8 specifically targets industrial environments with its extended temperature range.
