72V253L6PF

FIFOs Memory Overview

The Renesas 72V253L6PF is a synchronous FIFO memory device featuring a total storage capacity of 72K bits, organized as 4K x 18 or 8K x 9. It supports unidirectional data transfer with a maximum clock frequency of 166MHz and an access time of 4ns. The component operates within a supply voltage range of 3.15 V to 3.45 V and draws a maximum supply current of 35mA. It is housed in an 80-TQFP package measuring 14x14 mm and functions reliably across a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports First-Word-Fall-Through (FWFT) mode for immediate data availability upon read assertion
• Includes programmable full and empty flags for precise buffer status monitoring
• Features relay capability to enable cascading configurations for expanded memory depth

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Clock domain crossing interfaces in digital signal processing systems
• Data acquisition systems requiring low-latency memory staging

FIFOs Memory Procurement Notes

Verify the specific suffix L6PF to confirm the TQFP-80 package variant, as other suffixes indicate different physical footprints such as CABGA. Confirm RoHS compliance status, as some variants in this series may not meet current environmental directives. Check for End-of-Life notifications, as discontinuation notices have been issued for related packages in the 72V253 family. Ensure design-in compatibility with 3.3V logic levels.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous interface is required for high-throughput applications. The 4ns access time suits designs needing minimal latency between write and read operations. Consider the FWFT feature if the system architecture benefits from reading data immediately after writing without waiting for a clock cycle. Verify that the 80-pin TQFP footprint fits the PCB layout constraints compared to BGA alternatives.

FIFOs Memory Part Context

This part belongs to the Renesas 72V Super Sync II family of synchronous FIFOs. The family is characterized by high-speed operation and flexible configuration options. The 72V253 model specifically targets applications requiring moderate density with fast access times. It serves as a bridge between asynchronous and synchronous domains in complex integrated circuits.
