709269S15PFG8

Memory IC Overview

The Renesas Electronics Corporation 709269S15PFG8 is a high-speed synchronous dual-port static random-access memory (SRAM) with a density of 256K bits, organized as 32K words by 8 bits. It operates on a single 5V power supply and features full synchronous operation on both ports. The device supports flow-through or pipelined output modes selectable via the FT/PIPE pin. It includes automatic power-down capabilities controlled by chip enables to minimize standby power consumption.

Memory IC Feature Summary

• Dual-port architecture allows simultaneous access to the same memory location without additional logic
• Full synchronous operation on both ports with separate upper-byte and lower-byte controls for bus matching
• Selectable flow-through or pipelined output mode on either port via the FT/PIPE pin
• Automatic power-down feature controlled by CE0 and CE1 permits low standby power mode

Memory IC Applications

• Applications requiring unidirectional or bidirectional data flow in bursts
• Systems needing depth expansion without additional logic using dual chip enables
• Multiplexed bus systems requiring byte-level control compatibility

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential legacy status. Confirm RoHS compliance requirements as older variants may not meet current environmental standards. Check moisture sensitivity level handling procedures during storage and assembly. Ensure voltage supply stability within specified tolerances for reliable operation.

Memory IC Selection Notes

Select this component when synchronous dual-port access is required for burst data transfers. Consider the 100-pin TQFP package constraints for board layout. Evaluate power consumption needs against the automatic power-down features. Verify temperature range suitability for the intended operating environment.
