7208L35JI8

Overview

The Renesas Electronics Corporation 7208L35JI8 is an asynchronous FIFO memory device belonging to the 7208L35 series. It features a storage capacity of 576K bits, organized as 64K words by 9 bits. The component supports unidirectional data transfer with a maximum access time of 35 nanoseconds and operates at a data rate of 22.22 MHz. It functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. The integrated circuit is housed in a 32-PLCC package with J-leads, measuring 14 mm by 11.46 mm. It is designed for surface mount installation and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides asynchronous first-in-first-out buffering for simultaneous read and write operations without clock synchronization requirements.
• Supports unidirectional data flow with a 9-bit word width suitable for parallel interface applications.
• Utilizes a 32-pin plastic leaded chip carrier package for compact surface-mount integration.

Applications

• Multiprocessing systems requiring data buffering between independent processors.
• Rate matching buffers for converting data speeds between different system components.
• Parallel interface data storage in industrial control equipment.

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. Check moisture sensitivity level handling procedures before assembly. Validate pin compatibility with existing PCB footprints. Review end-of-life notices for long-term availability constraints.

Selection Notes

Select this component when a 64K x 9 asynchronous FIFO structure is required for unidirectional data buffering. Ensure the design accommodates the 32-PLCC package dimensions and 4.5 V to 5.5 V power supply constraints. Consider the 35 ns access time for timing budget calculations. Verify that the commercial temperature range meets operational environment specifications.
