7203L15TPGI

Overview

The Renesas 7203L15TPGI is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K x 9. It features a unidirectional bus architecture and supports data rates up to 40MHz with a 15ns access time. The component operates on a single 5.0V supply voltage within the 4.5V to 5.5V range, drawing a maximum supply current of 120mA. It is housed in a 32-PLCC surface-mount package and functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Asynchronous operation allows buffering between digital systems with varying clock frequencies.
• Unidirectional data flow architecture simplifies interface design for specific data paths.
• Supports relay capability for signal integrity maintenance.

Applications

• High-speed communication system buffering
• Controller application data synchronization
• Digital signal processing pipeline staging

Procurement Notes

Verify RoHS compliance status carefully, as datasheets indicate this specific part may not meet current environmental standards compared to newer variants. Confirm package authenticity against the 32-PLCC specification. Check for discontinuance notices or PCN updates regarding label changes or assembly site modifications before finalizing procurement plans.

Selection Notes

Select this component when a 2K x 9 depth is required for unidirectional data buffering. Ensure the design accommodates the 32-PLCC surface-mount footprint and 5.0V logic levels. Consider alternative packages if lead-free requirements are mandatory, as this specific suffix may contain lead.

Part Context

This device belongs to the Renesas 7203 series of asynchronous FIFO memories. It shares architectural similarities with other members like the 7203L12J8 but differs in speed grade and packaging. The series is designed for high-performance data rate applications requiring reliable temporary storage between asynchronous domains.

Replacement Considerations

The IDT7203L15JI8 is a documented substitute offering identical electrical specifications in a PLCC package. Verify pin compatibility and environmental compliance differences before substitution.
