Overview
The Renesas 72261LA10PF8 is a SuperSync synchronous FIFO memory IC with a capacity of 144K bits, organized as 16K x 9. It operates at a maximum data rate of 100MHz with an access time of 8ns. The device supports First-Word-Fall-Through (FWFT) and retransmit capabilities. It functions within a supply voltage range of 3V to 3.6V and is housed in a 64-TQFP surface-mount package.
Feature Summary
- SuperSync synchronous architecture with clocked read and write controls
- First-Word-Fall-Through (FWFT) support for reduced latency
- Retransmit capability for reliable data handling
Applications
- High-speed data buffering
- Data transfer interfaces
- System synchronization
Procurement Notes
This component is officially obsolete and has been discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct procurement from Renesas Electronics Corporation. Ensure that any acquired units are verified for authenticity and storage history due to the end-of-life status.
Selection Notes
Select this part only if legacy compatibility with 5.0V logic families or specific 16K x 9 organization is required. Note that the Frequency Select pin has been removed in this variant compared to earlier versions. Verify that the 64-TQFP package fits the target PCB footprint and that the 3V-3.6V operating voltage aligns with the system power rails.
Part Context
The 72261LA10PF8 belongs to the 72261 series of SuperSync FIFOs. It is a specialized memory component designed for high-performance buffering applications where precise timing and data integrity are critical. The device represents a specific configuration within the broader Renesas memory portfolio, tailored for systems requiring fast, synchronous data flow management.
Replacement Considerations
As the part is obsolete, no official direct replacement is listed. Engineers must evaluate alternative FIFOs with similar 16K x 9 organization and synchronous operation, ensuring pin compatibility or designing adapter solutions.
