72261LA20PF

Overview

The 72261LA20PF is a synchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 144 kbit, organized as 16K x 9 bits. The device supports a data rate of 50 MHz with an access time of 12 ns. It operates within a supply voltage range of 3 V to 3.6 V and functions at temperatures between 0°C and 70°C. The component is housed in a 64-TQFP (14x14) surface-mount package.

Feature Summary

• Synchronous FIFO architecture for efficient data buffering
• Supports full-width first-in-first-out (FWFT) operation
• Capable of signal retiming and protocol conversion
• Configurable depth and width expansion capabilities

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between components operating at different clock domains
• Protocol conversion in communication interfaces
• Retiming signals in high-frequency logic circuits

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or existing stock. Verify RoHS compliance status and moisture sensitivity levels before procurement, as these specifications are critical for handling and assembly processes.

Selection Notes

Select this part when a synchronous FIFO with 16K x 9 organization and 12 ns access time is required. Ensure the system operates within the 3 V to 3.6 V supply range and 0°C to 70°C temperature limits. Consider the 64-TQFP package constraints for PCB layout. Evaluate alternative synchronous FIFOs if current production volumes are needed due to the obsolete status.

Part Context

The 72261LA20PF belongs to the 72V series of synchronous FIFO memories from Renesas. This series is designed for applications requiring reliable data buffering and interface matching. The device integrates control logic for read/write operations and status flags, facilitating easy integration into complex digital systems without external control overhead.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should evaluate newer synchronous FIFO devices from Renesas or other manufacturers that offer compatible pinouts, electrical characteristics, and functional equivalents.
