7201LA25JI8

Overview

The Renesas Electronics Corporation 7201LA25JI8 is an asynchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 28.5 MHz with a 25 ns access time. The component is housed in a 32-PLCC package and supports unidirectional bus operation. It includes retransmit capability but lacks programmable flags or first-word fall-through support.

Feature Summary

• Asynchronous read and write operations for simultaneous data handling
• Retransmit capability allows resetting the read pointer to its initial position
• Uses Full and Empty status flags to prevent data overflow and underflow
• CMOS parallel interface architecture

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering applications between mismatched clock domains
• Data acquisition systems needing temporary storage buffers

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm end-of-life status and availability through authorized distributors. Check for alternative packages if PLCC-32 is unavailable. Validate pin compatibility with existing designs before procurement.

Selection Notes

Select this component for applications requiring 512x9 word depth and 25 ns speed. Ensure system voltage matches the 4.5V to 5.5V range. Consider the 32-PLCC package constraints for PCB layout. Verify if retransmit functionality meets specific control requirements.

Part Context

Part of the 7201L series, designed for high-speed asynchronous FIFO applications. Compatible with standard CMOS logic levels. Offers reliable data buffering for digital signal processing and communication interfaces.
