7202LA35J8

Overview

The Renesas Electronics Corporation 7202LA35J8 is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It features a parallel interface and operates within a supply voltage range of 4.5V to 5.5V. The component has a maximum access time of 35ns and supports a data rate of 22.2MHz. It utilizes a 32-PLCC surface-mount package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports asynchronous read and write operations for independent clock domains
• Includes retransmit capability to reset the read pointer to its initial position
• Designed for multiprocessing and rate buffering applications

Applications

• Multiprocessing systems requiring data synchronization
• Rate buffer applications between different speed components
• Asynchronous data transfer interfaces

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility with existing designs before integration. Check for moisture sensitivity handling during storage and assembly processes.

Selection Notes

Consider the 35ns access time and 22.2MHz data rate when evaluating system timing requirements. Ensure the 9-bit word width matches the application's data bus needs. Verify that the 32-PLCC package fits the available PCB footprint. Assess thermal performance within the specified industrial temperature range.

Part Context

This component belongs to the 7202L series of asynchronous FIFO memories manufactured by Renesas Electronics. The series provides reliable data buffering solutions for digital systems. The 7202LA35J8 variant specifically offers 35ns access speed in a PLCC package, catering to moderate-speed parallel data transfer needs.

Replacement Considerations

The 7202LA12JG is listed as an upgrade alternative. Verify functional compatibility and pin alignment before substitution.
