7205L15JGI

Overview

The Renesas Electronics Corporation 7205L15JGI is an asynchronous FIFO memory device belonging to the 7205L series. It features a storage organization of 8K words by 9 bits, providing a total capacity of 72 kilobits. The component operates with a maximum clock frequency of 40 MHz and supports a typical access time of 15 nanoseconds. It functions within a supply voltage range of 4.5 V to 5.5 V and utilizes a unidirectional data bus configuration. The integrated circuit is housed in a 32-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount applications.

Feature Summary

• Asynchronous operation allowing independent read and write clock domains
• Unidirectional data flow capability for standard buffering applications
• CMOS technology ensuring low power consumption relative to older bipolar alternatives

Applications

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

Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited production runs. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before finalizing procurement orders.

Selection Notes

Select this part when asynchronous buffering with a 9-bit data width is required. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage constraints. Verify that the 15 ns access time meets the timing requirements of the target application interface. Consider the PLCC-32 footprint during PCB layout planning.

Part Context

This component is part of the Renesas 7205L family of asynchronous FIFOs. It serves as a specialized memory interface solution for managing data flow in digital systems. The device complements other members of the series which offer varying depths and speeds, providing engineers with options for specific bandwidth and latency requirements in embedded designs.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify electrical parameter equivalence if considering alternative brands. Note that newer generations may require level shifting or firmware adjustments due to architectural differences.
