72255LA10PFG8

Overview

The 72255LA10PFG8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 8K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 8ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 55mA. The device is housed in a 64-pin TQFP package (14x14mm) and is rated for operation between 0°C and 70°C.

Feature Summary

• Supports First-Word-Fall-Through (FWFT) functionality for immediate data availability upon read enable.
• Includes retransmit capability to allow repeated reading of the same data word without advancing the pointer.
• Provides programmable full and empty flags for precise buffer status monitoring.

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock domains
• Temporary storage in telecommunications equipment

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) requirements for handling. Check for specific packaging variations or alternate suffixes if original stock is unavailable. Ensure ESD protection protocols are followed during assembly.

Selection Notes

Select this component for applications requiring reliable synchronous data buffering with unidirectional flow. Consider the 18-bit width and 8K depth for matching interface requirements. Evaluate the 100MHz speed against system timing constraints. Verify power supply compatibility with the 3V to 3.6V operating range.

Part Context

This part belongs to the 72V series of synchronous FIFOs from Renesas. It shares architectural similarities with other devices in the family but is distinguished by its specific 8K x 18 organization and 100MHz performance rating. The series is designed for high-throughput memory applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require design adaptation or verification of pin-to-pin compatibility with newer generations.
