72255LA10TF8

Overview

The 72255LA10TF8 is a synchronous FIFO memory IC from Renesas Electronics, featuring an 8K x 18 bit organization and 144K total capacity. It operates with a 10ns read/write cycle time and 8ns access time at 100MHz. The device supports unidirectional data flow and functions on a 4V to 5.5V supply voltage. It is housed in a 64-TQFP (10x10) package and includes auto power-down capabilities for standby efficiency.

Feature Summary

• Synchronous operation with clocked read and write controls
• Fixed low first word data latency
• Auto power down functionality to minimize standby consumption

Applications

• High-speed data buffering
• Protocol conversion interfaces
• Data rate matching between asynchronous systems

Procurement Notes

Verify the specific suffix 'LA10TF8' against official Renesas documentation to confirm pinout and electrical characteristics. Note that RoHS compliance status may vary by production batch; check the latest datasheet revision for accurate regulatory information before integration into final designs.

Selection Notes

Select this component when a fixed latency synchronous FIFO is required for 18-bit wide data paths. Ensure the system operates within the specified 4V to 5.5V range and requires the 64-TQFP form factor. Verify that the 100MHz maximum frequency meets the target application's timing constraints.

Part Context

This part belongs to the 72255 SuperSync FIFO series, designed for high-performance memory applications. It replaces earlier variants by removing the Frequency Select pin, simplifying the interface while maintaining high-speed performance standards typical of Renesas memory solutions.

Replacement Considerations

Consult official substitution guides for compatible parts within the 72255 family or equivalent synchronous FIFOs with matching 8K x 18 depth and TQFP-64 packaging.
