7208L25JGI

Overview

The Renesas Electronics Corporation 7208L25JGI is an asynchronous FIFO memory device organized as 32K x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 25 ns. The component utilizes a 32-pin PLCC package and supports bidirectional data bus operation. Designed for CMOS technology, it provides reliable first-in-first-out data buffering capabilities suitable for high-speed digital systems requiring moderate storage depth.

Feature Summary

• Supports asynchronous read and write operations with simultaneous data transfer capability
• Provides status flags including Full and Empty indicators to manage data flow
• Features auto-retransmit functionality allowing pointer reset upon signal pulse

Applications

• Multiprocessing system data buffering
• Rate matching between asynchronous clock domains
• High-speed interface bridging in digital logic circuits

Procurement Notes

Verify the specific suffix JGI against official Renesas documentation to confirm pinout compatibility and temperature grade. Confirm RoHS compliance status as historical records may vary. Check for active discontinuation notices or end-of-life notifications prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a 32K x 9 word depth is required for asynchronous buffering applications. Ensure the system operates within the specified 4.5 V to 5.5 V voltage range. Consider the 32-PLCC package constraints during PCB layout design. Verify that the 25 ns access time meets the timing requirements of the target interface speed.
