709289L7PF8

Memory IC Overview

The Renesas Electronics Corporation 709289L7PF8 is a high-speed 64K x 16 bit synchronous Dual-Port Static RAM. It features true dual-port memory cells allowing simultaneous access of the same location from both ports. The device operates on a single 5V (±10%) power supply and supports flow-through or pipelined output modes via dedicated pins. It includes counter enable and reset features, dual chip enables for depth expansion without additional logic, and separate upper-byte and lower-byte controls for multiplexed bus compatibility. The component is housed in a 100-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous access to identical memory locations
• Full synchronous operation with registered inputs for minimal setup and hold times
• Configurable flow-through or pipelined output modes selectable via external pins
• Integrated address counter with enable and reset capabilities for burst data flow

Memory IC Applications

• High-speed unidirectional or bidirectional data flow applications
• Systems requiring simultaneous independent access to shared memory resources
• Burst-oriented data processing architectures utilizing internal counters
• Depth expansion configurations using multiple chip enables

Memory IC Procurement Notes

Verify the specific speed grade suffix matches the required timing specifications, as commercial variants differ from industrial ones. Confirm the packaging suffix corresponds to the desired shipping format, such as tube or tape and reel. Ensure the voltage supply aligns with the specified 5V tolerance range. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Memory IC Selection Notes

Select this component when simultaneous read/write access to the same address is required across two independent ports. Choose the pipelined mode for higher throughput applications where latency can be managed. Utilize the counter features for sequential data streaming tasks. Ensure the system design accommodates the 100-pin TQFP footprint and provides adequate thermal management for the typical active power consumption levels.
