72215LB10J8

Overview

The Renesas 72215LB10J8 is a synchronous FIFO memory device with a capacity of 9K organized as 512 words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 100 MHz with a maximum access time of 6.5 ns. The component utilizes a 68-pin PLCC package and features unidirectional bus directionality.

Feature Summary

• Synchronous first-in, first-out memory architecture for reliable data buffering
• High-speed operation supporting 100 MHz data rates
• Configurable programmable flags for status monitoring

Applications

• Data buffering in graphics systems
• Local area network interface buffering
• Interprocessor communication links

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against project specifications, noting that specific variants may not meet current environmental standards. Validate package integrity upon receipt due to moisture sensitivity classification.

Selection Notes

Select this component when a 512 x 18 word synchronous FIFO is required for high-speed data transfer applications. Ensure the system design accommodates the 68-PLCC package dimensions and the 4.5 V to 5.5 V operating voltage range. Consider the unidirectional data flow constraint during interface design.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs, designed for general-purpose data buffering. It shares architectural similarities with other members like the 72215LB25PF8 but differs in speed grade and package type. The series targets applications requiring deterministic latency and high throughput.

Replacement Considerations

The IDT72215LB10J8 is listed as an alias for this component. Verify pinout and electrical parameter compatibility before substitution. No other cross-manufacturer replacements are confirmed in public documentation.
