7202LA25J8

Overview

The Renesas 7202LA25J8 is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 33.3 MHz with a 20 ns access time. The component features unidirectional bus directionality and is housed in a 32-PLCC package. It functions within an industrial temperature range of 0°C to 70°C and draws a maximum supply current of 80 mA.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes auto-retransmit capability to reset the read pointer upon low pulse activation
• Provides status flags including Empty, Half-Full, and Full to prevent data overflow or underflow

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering between components operating at different clock speeds
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and pin alignment against the 32-PLCC specification before integration into final assemblies.

Selection Notes

Select this component when a 1K x 9 word depth is required for asynchronous buffering. Ensure the design accommodates the 4.5 V to 5.5 V supply range and 32-PLCC footprint. Consider the 20 ns access speed for timing constraints in the target application circuit.

Part Context

This part belongs to the Renesas 7200 series of high-speed CMOS FIFO memories. It shares functional compatibility with other members of the family while offering specific depth and speed characteristics tailored for industrial and commercial applications requiring reliable data buffering.

Replacement Considerations

Check for direct substitutes within the 7200 series such as the 7202L20J8 for faster access times. Verify pinout and electrical specifications match exactly before substitution.
