72240L15TPG

Overview

The Renesas 72240L15TPG is a synchronous FIFO memory device with a capacity of 64 x 8 bits. It operates on a single 5.0V supply and features a maximum data rate of 66.7 MHz with a 15 ns access time. The component utilizes a 28-pin plastic DIP package and supports industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Dual-port architecture with zero fall-through time for immediate data availability
• Configurable read and write clocks allowing asynchronous or coincidental operation
• Programmable status flags including empty, full, almost-empty, and almost-full indicators

Applications

• Graphics data buffering
• Local Area Network (LAN) interface buffering
• Interprocessor communication systems

Procurement Notes

Verify the specific suffix 'TPG' against official documentation to confirm lead-free status and RoHS compliance details. Confirm current production status as discontinuance notifications may apply to this series. Ensure compatibility with existing 28-pin DIP footprints during design validation.

Selection Notes

Select this component for applications requiring simple synchronous buffering with programmable status flags. Consider the 64-word depth and 8-bit width for moderate throughput requirements. Evaluate the 15 ns speed against system clock constraints and verify temperature range suitability for the intended environment.

Part Context

This part belongs to the 72420/72240 family of synchronous FIFOs designed for high-speed data buffering. It shares architectural similarities with other members in the series but differs in speed grade and packaging options. The 72240 variant typically offers higher performance compared to the base 72420 model.

Replacement Considerations

Official substitutes include the 72420L15TPG and 72420L10TPG within the same product family. Verify pinout compatibility and electrical specifications before substitution.
