72V245L20TF

FIFOs Memory Overview

The Renesas Electronics Corporation 72V245L20TF is a synchronous FIFO memory device belonging to the 72V series. It features an organization of 4K x 18 bits, providing a total storage capacity of 72 kilobits. The component supports unidirectional data transfer with a maximum clock frequency of 50 MHz and an access time of 12 nanoseconds. It operates within a supply voltage range of 3 V to 3.6 V and draws a maximum supply current of 30 mA. The device is housed in a 64-pin TQFP package (14x14 mm) and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) timing for rapid data availability
• Features programmable status flags including empty, full, half-full, and almost-empty/almost-full indicators
• Capable of expansion in both depth and width for custom memory configurations
• Includes asynchronous or coincident read and write clock controls

FIFOs Memory Applications

• Optical disk controllers
• Local Area Networks (LANs)
• Interprocessor communication systems

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors as this part number may be obsolete. Confirm RoHS compliance status, as older batches may not meet current environmental regulations. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the specific suffix matches the required temperature grade and package variant for your design.

FIFOs Memory Selection Notes

Select this component when a 4K x 18 synchronous FIFO with 12 ns access time is required. Consider the 72V245L10PFG as a potential upgrade alternative if faster 6.5 ns performance is needed. Verify that the 3.3V logic levels are compatible with the system interface. Ensure the 64-TQFP package fits the PCB footprint constraints.

FIFOs Memory Part Context

The 72V245L20TF belongs to the Renesas 72V family of high-performance synchronous FIFOs. This series is characterized by 3.3V operation and 5V input tolerance, making it suitable for mixed-voltage systems. The 72V245 model specifically offers 72Kb density with 18-bit wide data paths, balancing speed and capacity for buffering applications.

FIFOs Memory Replacement Considerations

The 72V245L10PFG is listed as an upgrade replacement offering faster 6.5 ns access times. Verify pin compatibility and electrical specifications before substitution.
