72255LA15PFGI8

Overview

The Renesas 72255LA15PFGI8 is a synchronous FIFO memory device with a capacity of 144K bits, organized as 8K words by 18 bits. It operates at a data rate of 66.7MHz with an access time of 10ns. The component supports uni-directional bus architecture and includes programmable flags and First Word Fall Through (FWFT) functionality. It functions within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP package measuring 14x14mm and is rated for operation between -40°C and 85°C.

Feature Summary

• Supports First Word Fall Through (FWFT) for reduced latency
• Includes programmable status flags for buffer management
• Uni-directional data transfer architecture

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

This component is officially classified as obsolete or last-time-buy by the manufacturer. Verify availability through authorized distributors for final procurement batches. Ensure strict adherence to RoHS3 compliance standards during integration. Confirm moisture sensitivity level (MSL 3) handling requirements before PCB assembly to prevent package damage.

Selection Notes

Select this part for applications requiring 18-bit wide synchronous buffering with low access times. Compare against the 72235LB series for similar performance but different voltage ranges. Consider the 72V265LA series if higher density and lower voltage operation are required instead of this specific 5V variant.

Part Context

Part of the Renesas 7200 Series SuperSync FIFO family. This specific model provides 8K x 18 organization. It shares architectural similarities with other IDT/Renesas high-performance FIFOs designed for parallel data path synchronization in digital signal processing and telecommunications infrastructure.

Replacement Considerations

Official substitutes include the 72235LB15PFGI8 from the same manufacturer family. Cross-reference pinouts and electrical specifications carefully when evaluating alternative sources due to the obsolete status.
