7200L15J8

Overview

The Renesas 7200L15J8 is an asynchronous FIFO memory device with a storage capacity of 2.25K bits, organized as 256 words by 9 bits. It features a maximum data rate of 40MHz and a typical access time of 15ns. The component operates on a single 5V power supply ranging from 4.5V to 5.5V, with a maximum supply current of 80mA. It utilizes a 28-pin PDIP package for through-hole mounting and supports unidirectional bus operation.

Feature Summary

• Asynchronous first-in-first-out memory architecture for temporary data buffering
• CMOS parallel interface supporting standard logic levels
• Single-chip integration of memory array and control logic

Applications

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

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as historical batches may vary. Check for end-of-life notices or obsolescence announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a small-capacity asynchronous FIFO is required for 9-bit wide data paths. Ensure the system voltage aligns with the 4.5V to 5.5V range. Consider the 28-PDIP package constraints if surface-mount alternatives are preferred for modern assembly processes.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7201LA15J8 but differs in depth and organization. The series provides versatile buffering solutions for legacy and industrial applications requiring reliable parallel data transfer.

Replacement Considerations

Official substitutes include the 7201LA12SOG. Verify functional equivalence regarding depth, width, and timing parameters before implementation.
