709379L9PFI8

Memory IC Overview

The 709379L9PFI8 is a high-speed synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage organization of 16K x 18 bits, providing a total capacity of 288 kbit. The device supports a maximum clock frequency of 83 MHz with an access time of 9 ns. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin TQFP surface-mount package and is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location by two separate controllers.
• Configurable output modes allow selection between flow-through or pipelined operation on either port via dedicated control pins.
• Automatic power-down functionality reduces standby current when chip enable signals are deactivated.
• Integrated counter enable and reset features support depth expansion without requiring additional external logic.

Memory IC Applications

• High-performance communication buffer systems
• Bidirectional data flow burst applications
• Unidirectional data flow processing

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm moisture sensitivity level handling requirements prior to assembly. Check for specific RoHS compliance status variations across manufacturing lots. Ensure pinout compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component for designs requiring simultaneous read/write operations from multiple masters. Consider the 100-pin TQFP package constraints for thermal management. Evaluate the 5V I/O tolerance against system logic levels. Verify that the 9 ns access time meets the target bus speed requirements.

Memory IC Part Context

This device belongs to the 709379 series of synchronous dual-port RAMs. It shares architectural similarities with other members like the 709379L9PF but differs in packaging and suffix specifications. The series is designed for burst data transfer optimization in embedded systems.
