72255LA10TF

Overview

The Renesas Electronics Corporation 72255LA10TF is a synchronous FIFO memory device with a capacity of 144K bits, organized as 8K words by 18 bits. It operates at a data rate of 100MHz with an access time of 8ns. The component supports a supply voltage range of 3V to 3.6V and draws a maximum supply current of 30mA. It features uni-directional bus architecture and is housed in a 64-TQFP package.

Feature Summary

• Synchronous operation for reliable data buffering
• Uni-directional bus interface
• Programmable status flags support
• First Word Fall Through (FWFT) capability

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between asynchronous logic domains
• Memory buffering in communication equipment

Procurement Notes

Verify the exact suffix configuration against the manufacturer's datasheet to ensure compatibility with specific voltage and temperature requirements. Confirm that the RoHS status aligns with project constraints, as older revisions may not meet current environmental standards. Cross-reference the part number with official Renesas documentation to validate availability and lead times through authorized channels.

Selection Notes

Select this component when a high-speed synchronous FIFO with 18-bit width is required. Ensure the system operates within the specified 3V to 3.6V supply range. Consider the 64-TQFP package dimensions for PCB layout. Verify that the 100MHz data rate meets the application's throughput needs and that FWFT functionality is necessary for the design.

Part Context

This part belongs to the Renesas 72V series of SuperSync FIFOs. It is designed for high-performance applications requiring fast data transfer rates. The 72V series typically offers low power consumption and high density compared to earlier generations. This specific model provides a balance of speed and memory depth for complex digital designs.

Replacement Considerations

The 72V255L15TF is listed as an obsolete upgrade path. Verify electrical compatibility before substitution. Check for pin-to-pin equivalence and ensure the replacement meets all timing and voltage specifications required by the original design.
