709289L9PF8

Memory IC Overview

The Renesas Electronics Corporation 709289L9PF8 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 supports flow-through or pipelined output modes on either port via dedicated pins and includes counter enable and reset features for address generation. It operates with full synchronous control on both ports, utilizing separate upper-byte and lower-byte controls for multiplexed bus compatibility. The component utilizes a single 5V power supply and is available in a 100-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous access to identical memory locations from both ports
• Configurable flow-through or pipelined output modes selectable independently for each port
• Integrated address counter with enable and reset capabilities for sequential burst operations
• Dual chip enables facilitating depth expansion configurations without requiring external logic

Memory IC Applications

• High-speed data buffering in unidirectional or bidirectional burst data flows
• Interfacing between asynchronous systems requiring registered input/output timing
• Depth expansion memory banks in parallel processing architectures
• Multiplexed bus systems requiring independent byte-level control

Memory IC Procurement Notes

Verify the specific speed grade and temperature range requirements against the ordering suffixes provided in the official datasheet. Confirm that the 100-pin TQFP package dimensions match the target PCB footprint. Ensure the design accommodates the required 5V power supply voltage and current consumption levels during active and standby states. Check for any end-of-life notices or last-time-buy notifications associated with this specific manufacturer part number before finalizing procurement plans.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without arbitration logic. Consider the pipelined mode for higher throughput applications where latency can be managed, or flow-through mode for simpler timing constraints. Verify that the system clock frequency aligns with the specified cycle time limits for the chosen speed grade. Ensure the application environment remains within the specified commercial or industrial temperature ranges supported by the selected variant.

Memory IC Part Context

This device belongs to the IDT709289L series of synchronous dual-port SRAMs. It is manufactured using CMOS high-performance technology optimized for low-power operation. The series supports both commercial and industrial temperature grades depending on the specific speed bin. The component integrates address registers and control logic to minimize setup and hold times, facilitating high-speed system designs.

Memory IC Replacement Considerations

Consult the official datasheet for compatible pin-to-pin replacements within the same family. Verify that alternative parts support the required synchronous dual-port functionality and pipelined/flow-through modes. Ensure electrical characteristics such as voltage levels and timing parameters meet the original design specifications.
