72255LA15PFG

Overview

The Renesas 72255LA15PFG is a synchronous FIFO memory device with a storage capacity of 144K bits, organized as 8K words by 18 bits. It operates at a maximum data rate of 66.7 MHz with an access time of 10 ns. The component supports unidirectional bus direction and functions within a supply voltage range of 4 V to 5.5 V. It is housed in a 64-TQFP package and is designed for surface mount installation.

Feature Summary

• Synchronous operation with high-speed data transfer capabilities
• Unidirectional data flow architecture
• Standard TTL-compatible logic levels

Applications

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

Procurement Notes

Verify RoHS compliance status carefully as sources vary. Confirm package type matches design requirements. Check for end-of-life notifications from the manufacturer. Ensure supply voltage specifications align with target circuit design before procurement.

Selection Notes

Select this part for applications requiring 18-bit wide synchronous FIFO buffers. Compare against 72V255 series for voltage compatibility differences. Verify pinout compatibility if replacing legacy IDT components. Consider thermal performance within the TQFP-64 package constraints.

Part Context

This component belongs to the Renesas 72255LA series of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB but differs in organization and voltage requirements. The LA suffix typically indicates specific voltage and feature sets within the product family.

Replacement Considerations

IDT72255LA15PFG is a direct equivalent part number. Verify pin-to-pin compatibility and electrical specifications before substitution.
