7204L15TPGI

Overview

The Renesas Electronics Corporation 7204L15TPGI is an asynchronous dual-port FIFO memory device housed in a 28-pin PDIP package. It features a storage organization of 8K x 9 bits, providing a total capacity of 72 kilobits. The component operates on a single 5.0V supply voltage and supports unidirectional data transfer. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C. This specific part number is classified as obsolete and has been discontinued by the manufacturer.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles without clock synchronization
• Dual-port architecture allowing access from two distinct systems or processors
• Auto-retransmit capability to reset the read pointer upon signal assertion

Applications

• Multiprocessing systems requiring data buffering between disparate clock domains
• Rate matching buffers for serial-to-parallel data conversion
• Interface bridging between high-speed peripherals and slower processing units

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability is restricted to existing distributor stock or surplus markets. Buyers must confirm the authenticity of legacy inventory and check for potential moisture sensitivity degradation due to age. Design-in should prioritize replacement components immediately to ensure long-term supply chain stability.

Selection Notes

Engineers selecting this part must account for its obsolete status and limited future availability. The 8K x 9 organization and 5.0V logic levels define its compatibility constraints. Alternative solutions should be evaluated based on pin compatibility and functional equivalence to the 7204 series. Transitioning to newer generations requires re-evaluation of timing parameters and power consumption profiles.

Part Context

The 7204L15TPGI belongs to the Renesas 7204L15 family of asynchronous FIFOs. This series is characterized by high-speed access times and flexible expandability options. The 'TPGI' suffix indicates the specific 28-pin plastic dual in-line package configuration with lead-free plating compliant with historical RoHS standards.

Replacement Considerations

Direct substitutes include the 7204L12JG. Engineers should verify pinout compatibility and electrical specifications before integration.
