72215LB10PFG

Overview

The Renesas Electronics Corporation 72215LB10PFG is a synchronous First-In, First-Out (FIFO) memory device. It features a storage organization of 512 words by 18 bits, providing a total capacity of 9 kilobits. The component supports unidirectional data transfer with a maximum clock frequency of 100 MHz and an access time of 6.5 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 60 mA. The device is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads, suitable for surface-mount applications.

Feature Summary

• Synchronous FIFO architecture with dedicated read and write clocks for reliable data buffering
• High-speed operation supporting 100 MHz clock frequencies with 6.5 ns access times
• Programmable full and empty flags for status monitoring
• Unidirectional bus configuration for single-direction data flow

Applications

• Data buffering in graphics systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the exact suffix PFG against official Renesas documentation to confirm pinout and package dimensions, as variations exist within the 72215 series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy components may have specific environmental declarations. Check for end-of-life notices or obsolescence warnings prior to procurement planning.

Selection Notes

Select this component when a 512x18 word depth is required for synchronous data buffering. Ensure the system design accommodates the 4.5V to 5.5V operating voltage range. Consider the 68-PLCC package constraints for PCB layout. Verify that the 100 MHz speed requirement aligns with the system clock capabilities.

Part Context

The 72215LB10PFG belongs to the Renesas 72215 series of high-performance synchronous FIFOs. This series is designed for applications requiring fast data transfer rates and flexible memory configurations. The LB variant typically denotes specific speed grades and voltage characteristics within the broader 72215 product family.

Replacement Considerations

Cross-reference part numbers such as IDT72215LB10PFG for potential equivalents from Integrated Device Technology, which was acquired by Renesas. Verify functional compatibility regarding pinouts, timing parameters, and electrical specifications before substitution.
