7203L25JI8

Overview

The Renesas 7203L25JI8 is an asynchronous FIFO memory device with a storage organization of 2K x 9 bits, providing a total capacity of 18.4 kbit. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 28.5 MHz with a 25 ns access time. The component features bidirectional data buses and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation allowing simultaneous independent read and write cycles
• Bidirectional data bus architecture for flexible interface connectivity
• Retransmit capability enabling pointer reset functionality

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between asynchronous data streams
• Parallel FIFO memory interfaces

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm end-of-life status and limited availability through authorized channels. Ensure package compatibility with existing PCB footprints for the 32-PLCC configuration before procurement.

Selection Notes

Select this component for applications requiring 2K x 9 bit depth with 5V logic levels. Verify that bidirectional bus requirements are met. Consider alternative models if RoHS compliance or active manufacturing status is mandatory for the project lifecycle.

Part Context

This part belongs to the Renesas 7203 series of CMOS parallel FIFOs. It shares functional similarities with other members like the 72V03L25JI8 but differs in supply voltage specifications and bus directionality. The series targets high-speed asynchronous memory buffering needs.
