72231L25PFG8

Overview

The Renesas Electronics Corporation 72231L25PFG8 is a FIFO memory component with a capacity of 2K x 9. It supports both asynchronous and synchronous operation modes, featuring a maximum clock frequency of 40MHz and an access time of 15ns. The device is housed in a 32-TQFP package measuring 7x7 mm. It operates within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Supports dual-mode asynchronous and synchronous FIFO operations
• Uni-directional data bus architecture
• Compact surface-mount packaging

Applications

• Data buffering in high-speed digital systems
• Interface bridging between different clock domains
• Temporary storage in communication protocols

Procurement Notes

Verify the specific operating temperature grade, as sources indicate variations between 0°C-70°C and -40°C-85°C for similar family members. Confirm package dimensions match the 7x7 mm specification. Check current availability status as distribution channels may list obsolete or alternative stock.

Selection Notes

Select this component when a small-depth FIFO is required for 9-bit wide data paths. Ensure the system design accommodates the 40MHz synchronous limit or utilizes the asynchronous mode for simpler timing requirements. Verify voltage compatibility with the target logic levels.

Part Context

This part belongs to the Renesas 72231 series of FIFO memories. It is designed for applications requiring moderate data buffering capabilities with flexible timing control. The series offers various configurations to suit different interface needs in embedded systems.

Replacement Considerations

Check for direct pin-compatible substitutes within the same Renesas family that offer extended temperature ranges if the application requires -40°C operation. Verify functional equivalence for synchronous/asynchronous modes before substitution.
