7208L35J

Overview

The Renesas Electronics Corporation 7208L35J is a CMOS parallel First-In-First-Out (FIFO) memory device. It features an organization of 32K x 9 bits, providing a total storage capacity of 288 kbit. The component operates with an asynchronous interface and supports a maximum clock frequency of 22.22 MHz, achieving a typical access time of 35 ns. It functions within a supply voltage range of 4.5 V to 5.5 V and is housed in a PLCC-32 package.

Feature Summary

• Asynchronous FIFO architecture for unidirectional data buffering
• CMOS technology ensuring compatibility with standard logic levels
• Parallel interface supporting high-speed data transfer operations

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in digital signal processing chains

Procurement Notes

Verify the specific suffix designation carefully, as the exact model 7208L35J may be listed under aliases such as IDT7208L35J8 or variants like 7208L35J8. Confirm RoHS compliance status, as older revisions often lack lead-free certification. Check for End-of-Life notices and limited availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a 32K x 9 depth is required for unidirectional asynchronous buffering. Ensure the system design accommodates the 4.5V to 5.5V power supply requirements. Verify that the PLCC-32 surface mount package aligns with the PCB layout constraints and thermal management strategies of the target application.

Part Context

This part belongs to the Renesas 7208 series of high-performance FIFO memories. It shares architectural similarities with other members like the 7208L25JI but differs in speed grade and specific timing characteristics. The series is designed for applications requiring reliable data synchronization without complex control logic overhead.

Replacement Considerations

Potential substitutes include the IDT7208L35J8. Verify pinout compatibility and electrical specifications against the original datasheet before implementation.
