709289L6PF8

Memory IC Overview

The Renesas Electronics Corporation 709289L6PF8 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 FT/PIPE pins. It operates with a single 5V (±10%) TTL-compatible power supply and includes automatic power-down features controlled by CE0 and CE1 for low standby power consumption.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous access to identical memory locations
• Configurable flow-through or pipelined output modes selectable via FT/PIPE pins
• Integrated address counter with enable and reset capabilities for burst data flows
• Dual chip enables facilitating depth expansion without additional external logic

Memory IC Applications

• High-speed unidirectional or bidirectional data flow in bursts
• Multiplexed bus systems requiring byte-level control compatibility
• Depth expansion configurations utilizing multiple chip enables
• Systems requiring fast interleaved memory operations with address counters

Memory IC Procurement Notes

Verify the specific speed grade suffix, as the '6' designation indicates a 6ns maximum clock-to-data valid time in pipelined mode. Confirm package integrity for the 100-pin TQFP form factor. Ensure voltage supply stability within the 4.5V to 5.5V range to maintain synchronous operation timing specifications. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. The choice between flow-through and pipelined modes depends on system latency requirements versus throughput needs. Verify that the host controller can manage the separate upper-byte and lower-byte controls for proper bus matching. Consider the industrial temperature availability if operating conditions exceed standard commercial ranges.

Memory IC Part Context

This device belongs to the IDT709289L series of high-speed synchronous dual-port SRAMs. It is manufactured using CMOS technology optimized for low power consumption while maintaining high performance. The series supports various speed grades and packaging options to accommodate different system integration constraints and thermal environments.

Memory IC Replacement Considerations

Consult official datasheets for cross-reference part numbers from Integrated Device Technology or Renesas. Verify pinout compatibility and electrical characteristics before substituting. Ensure the replacement supports the required synchronous interface and dual-port functionality.
