7202LA25JGI

Overview

The Renesas Electronics Corporation 7202LA25JGI is an asynchronous FIFO memory device with a storage capacity of 9 kbit, organized as 1K x 9. It features a unidirectional bus and supports a maximum clock frequency of 28.5 MHz. The access time is specified at 25 ns. Operating voltage ranges from 3 V to 3.6 V, with a maximum supply current of 80 mA. It operates within a temperature range of -40°C to +85°C and is housed in a 32-PLCC package.

Feature Summary

• Provides asynchronous data buffering for high-speed digital systems
• Supports unidirectional data transfer with dedicated read and write paths
• Includes status flags for full and empty conditions

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between components operating at different clock speeds
• High-speed serial-to-parallel conversion circuits

Procurement Notes

Verify the specific suffix JGI confirms the PLCC-32 surface mount package and commercial/industrial temperature grade. Confirm RoHS compliance status through official Renesas documentation, as older variants may differ. Check for moisture sensitivity level requirements during storage and handling. Ensure the unidirectional architecture matches system design needs rather than bidirectional alternatives.

Selection Notes

Select this component when a 1K x 9 depth is required for asynchronous buffering. The 25 ns access time suits moderate-speed applications. Verify that the 3.3V logic levels align with the host system. Consider the 32-PLCC footprint for PCB layout constraints. Compare against the 72V02L25JGI if bidirectional I/O or lower power consumption is necessary.

Part Context

This part belongs to the Renesas 7202L series of CMOS asynchronous FIFOs. It is designed for general-purpose data storage and flow control. The series offers various access times and organizations to fit diverse interface requirements. It serves as a standard solution for decoupling data rates in embedded systems.

Replacement Considerations

The IDT7202LA25JGI is a confirmed equivalent part number from the same manufacturer lineage. Verify pin compatibility and electrical specifications before substitution.
