72V245L20TFI

FIFOs Memory Overview

The 72V245L20TFI is a synchronous first-in, first-out (FIFO) memory device manufactured by Renesas Electronics. It features a storage capacity of 72 kbit organized as 4K x 18 bits. The component supports unidirectional data transfer with a maximum clock frequency of 50 MHz and an access time of 12 ns. 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 LQFP package and is rated for industrial temperature operation from -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports dual-clock operation allowing asynchronous or coincident read and write clocks for flexible data buffering.
• Includes programmable almost-empty and almost-full flags with default settings for efficient flow control.
• Features output enable functionality that places the output data bus in a high-impedance state.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as specifications may vary by production lot. Check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches the required package and temperature grade. Validate lead-free status against project regulatory constraints before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when a 4K x 18 synchronous FIFO is required for 3.3V logic systems. Choose this part over faster variants if the 50 MHz speed limit satisfies system timing requirements. Consider the 64-pin LQFP package for surface-mount assembly compatibility. Verify that the 12 ns access time meets the interface latency needs of the target application design.

FIFOs Memory Part Context

This device belongs to the 72V245 series of 3.3V synchronous FIFOs. It serves as a specialized memory solution for buffering data streams between components operating at different speeds. The series provides reliable data integrity for high-speed digital interfaces requiring precise synchronization and flow management capabilities.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible upgrades such as the 72V245L10PFG for higher speed requirements. Verify functional equivalence with other 4K x 18 synchronous FIFOs from alternative manufacturers. Ensure any substitute maintains the same 3.3V supply voltage and 64-pin LQFP package dimensions.
