709379L9PF8

Memory IC Overview

The 709379L9PF8 is a high-speed synchronous Dual-Port Static Random Access Memory (SRAM) manufactured by Renesas Electronics. It features a memory organization of 16K x 18 bits, providing a total storage capacity of 288 kbit. The device supports full synchronous operation on both ports with an access time of 9 ns. It operates within a voltage range of 4.5 V to 5.5 V and functions at temperatures between 0°C and +70°C. The component is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from either port.
• Synchronous interface supporting both flow-through and pipelined output modes selectable via external control pins.
• Integrated automatic power-down functionality controlled by chip enable signals for low standby power consumption.
• TTL-compatible single 5V power supply operation with separate upper-byte and lower-byte controls.

Memory IC Applications

• High-speed data buffering in burst transfer applications
• Bidirectional data flow systems requiring simultaneous port access
• Multiplexed bus interfaces with byte-matching compatibility

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance requirements as indicated in official documentation. Check moisture sensitivity level handling procedures before assembly. Validate pinout and electrical specifications against current design needs. Ensure replacement parts meet identical functional and environmental standards.

Memory IC Selection Notes

Select this component for designs requiring synchronous dual-port memory with 18-bit word width. Consider the 100-pin TQFP package constraints for PCB layout. Evaluate thermal performance within the commercial temperature range. Verify power supply stability within the specified voltage limits. Assess system timing requirements against the 9 ns access specification.

Memory IC Part Context

This part belongs to the 709379 series of synchronous dual-port RAMs. It shares architectural similarities with other members like the 709279 but differs in density and bit-width configuration. The series is designed for high-performance memory applications requiring concurrent access capabilities without external arbitration logic.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT709379L9PF8. Verify pin compatibility and electrical parameters before substitution. Ensure the alternative meets the same package and temperature specifications.
