72215LB25PF

Overview

The Renesas Electronics Corporation 72215LB25PF is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It features a storage organization of 512 x 18 bits, providing a total capacity of 9 kilobits. The component supports unidirectional data transfer with a maximum clock frequency of 40 MHz and an access time of 25 ns. 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 64-pin Thin Quad Flat Package (TQFP) with dimensions of 10x10 mm.

Feature Summary

• Synchronous FIFO architecture with dedicated read and write clocks for precise data buffering
• Programmable status flags indicating full, empty, and half-full conditions
• Unidirectional bus interface designed for high-speed data transfer applications

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package integrity as moisture sensitivity level requires controlled storage. Check RoHS compliance documentation as indicated by manufacturer specifications. Validate pinout compatibility with existing PCB layouts before integration into new designs.

Selection Notes

Select this component when a 512 x 18 synchronous FIFO is required for unidirectional data flow. Ensure system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 64-TQFP package constraints for board space. Verify that the 40 MHz speed meets timing requirements for the specific application interface.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories, which includes various densities and speeds. The 72215 variant specifically targets 18-bit wide data paths. It serves as a legacy solution for buffering applications where synchronous control is preferred over asynchronous handshaking protocols.
