72215LB10PF8

Overview

The Renesas Electronics 72215LB10PF8 is a synchronous FIFO memory device with a capacity of 9K organized as 512 words by 18 bits. It operates at a maximum data rate of 100MHz and features a minimum access time of 6.5ns. The component supports unidirectional bus directionality and includes programmable flags for status monitoring. It functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 60mA. The device is housed in a 64-pin TQFP package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous first-in, first-out memory architecture with clocked read and write controls
• Programmable full and empty flag outputs for buffer status indication
• High-speed operation supporting up to 100MHz data rates
• Unidirectional data bus configuration for dedicated input or output applications

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock speeds
• Temporary storage in telecommunications equipment data streams
• Memory expansion in industrial control system architectures

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm the exact pinout and package dimensions, as variations exist within the 72215 series. Confirm RoHS compliance status directly with the manufacturer, as legacy parts may have restricted material declarations. Check for active End-of-Life notices or Production Change Notices that may affect long-term availability or replacement part numbers.

Selection Notes

Select this component when a 512x18 word synchronous FIFO is required for unidirectional data flow. Ensure the design accommodates the 4.5V to 5.5V power supply requirements and the 64-pin TQFP footprint. Verify that the 6.5ns access time meets the timing constraints of the target application. Consider alternative packages if surface mount space is limited, as other variants in the series offer different form factors.

Part Context

The 72215LB10PF8 belongs to the Renesas 72215 series of synchronous FIFOs, designed for high-performance data buffering. This series is characterized by its ability to handle wide data buses and high clock frequencies, making it suitable for demanding embedded applications. The LB variant typically denotes specific speed grades and voltage ranges within the broader product family.

Replacement Considerations

Consult official Renesas cross-reference guides for direct replacements. Note that IDT-branded equivalents may exist due to historical corporate relationships, but verify electrical compatibility and pinouts before substitution.
