72V255LA15TFGI8

FIFOs Memory Overview

The 72V255LA15TFGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features an organization of 8K x 18 bits, providing a total storage capacity of 144 Kbits. The component operates with a maximum clock frequency of 66.7 MHz and supports a data rate corresponding to a 10 ns access time. It functions as a unidirectional buffer within the SuperSync family, designed for 3.3 V supply voltage operation ranging from 3 V to 3.6 V. The device is housed in a 64-pin TQFP package measuring 14x14 mm and supports programmable flags for status monitoring.

FIFOs Memory Feature Summary

• Supports retransmit operations with fixed, low first word data latency time
• Features independent read and write clocks allowing simultaneous read and write operations
• Includes programmable Almost-Empty and Almost-Full flags for flexible status signaling
• Provides auto power down capability to minimize standby power consumption

FIFOs Memory Applications

• Data buffering in telecommunications systems
• Video signal processing applications
• Networking equipment data flow management
• Interprocessor communication interfaces

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, as older batches may not meet current regulations. Validate package dimensions and pinout compatibility during integration planning. Check for moisture sensitivity handling requirements prior to assembly. Review official product change notifications for any manufacturing updates or material substitutions.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit width is required. Ensure system design accommodates the 3.3 V operating voltage range. Verify that the 64-pin TQFP package fits the available PCB footprint. Consider the 10 ns access time relative to system clock speeds. Evaluate if the 8K depth meets the buffering requirements for the intended application throughput.

FIFOs Memory Part Context

This part belongs to the 72V2x5 SuperSync FIFO series, which offers functionally compatible versions of the earlier 5 Volt 722x5 family but optimized for 3.3 V operation. The 'L' suffix typically denotes specific speed or package variations within the lineup. This series is engineered for high-performance data buffering in digital signal processing and communication networks requiring reliable synchronization between different clock domains.

FIFOs Memory Replacement Considerations

Official substitutes include the 72V255L15TF and 72V255L15TFGI8. Verify pinout and electrical specifications match before substitution. Cross-reference datasheets for any functional differences in flag logic or power characteristics.
