709379L7PF8

Memory IC Overview

The Renesas Electronics Corporation 709379L7PF8 is a high-speed synchronous dual-port static random access memory (SRAM) device. It features a storage organization of 16K x 18 bits, providing a total capacity of 288 kbit. The component supports a maximum access time of 7 ns and operates on a single 5V power supply within the range of 4.5V to 5.5V. It utilizes a parallel interface and is housed in a 100-pin TQFP package suitable for surface mount technology.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to shared memory locations by two distinct masters.
• Synchronous operation with full clock synchronization on both ports for precise timing control.
• Automatic power-down capability controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible single 5V power supply requirement simplifying integration into standard logic systems.

Memory IC Applications

• High-speed data buffering in network communication equipment
• Cache memory implementation in embedded processing systems
• FIFO buffers for burst data transfer applications

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance requirements as older batches may not meet current environmental standards. Check moisture sensitivity level handling procedures during assembly. Validate pinout compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data flow is required between two processors. Ensure system voltage aligns with the specified 5V operating range. Consider the 100-pin TQFP package constraints for board space allocation. Evaluate thermal performance within the commercial temperature range for the intended application environment.

Memory IC Part Context

This part belongs to the 709379 series of synchronous dual-port RAMs from Renesas. It shares architectural similarities with other members like the 709379L12PF8 but offers faster access speeds. The series is designed for applications requiring high bandwidth and low latency memory solutions.

Memory IC Replacement Considerations

Direct substitutes include the IDT709379L7PFG8. Verify pin-to-pin compatibility and electrical specifications before substitution. Alternative packages such as BGA variants may require adapter solutions or redesign.
