7208L35JI

Overview

The Renesas Electronics Corporation 7208L35JI is an asynchronous FIFO memory device belonging to the 7208 series. It features a storage organization of 64K x 9 bits, providing a total capacity of 576 Kbits. The component supports unidirectional data transfer with a maximum clock frequency of 22.22 MHz and an access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. The device is housed in a 32-PLCC package with J-leads and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration.
• Unidirectional bus architecture simplifies system design by directing data flow from input to output ports.
• CMOS technology ensures low power consumption while maintaining high-speed data throughput capabilities.

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock speeds
• Temporary data storage in telecommunications equipment

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check for end-of-life notices or discontinuation announcements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 64K x 9 asynchronous FIFO is required with 35 ns access speed. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the PLCC-32 package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the Renesas 7208 series of CMOS parallel FIFOs. It shares architectural similarities with other members like the 7208L25JI but differs in access time specifications. The series is designed for general-purpose memory buffering applications requiring reliable asynchronous data handling.

Replacement Considerations

The IDT7208L35J8 is listed as an alias for this component. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult official datasheets for both parts to confirm functional interchangeability.
