72255LA20PFI

Overview

The 72255LA20PFI is a synchronous FIFO memory component manufactured by Renesas Electronics Corporation. It features an 8K x 18 bit organization, providing a total storage capacity of 144 kbit. The device supports a data rate of 50 MHz with a typical access time of 12 ns. It operates within a supply voltage range of 3 V to 3.6 V and is housed in a 64-LQFP package. The component is designed for uni-directional data transfer applications.

Feature Summary

• Supports synchronous operation with clocked read and write controls
• Features an 8K x 18 bit memory architecture for high-density buffering
• Includes programmable flags for status monitoring

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic domains
• Digital signal processing pipeline staging

Procurement Notes

Verify the exact operating voltage requirements against your system design, as this component specifies a 3 V to 3.6 V range. Confirm package compatibility with your PCB footprint, specifically the 64-LQFP dimensions. Check for moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure that the synchronous interface timing aligns with your controller specifications.

Selection Notes

Select this component when a synchronous FIFO with 18-bit width and 50 MHz performance is required. It is suitable for applications needing reliable data buffering between different clock domains. Consider the 64-LQFP package size for space-constrained designs. Verify that the 3 V to 3.6 V supply voltage matches your power distribution network.

Part Context

This part belongs to the 72V255 series of SuperSync FIFOs from Renesas. It is functionally similar to other members of the family but specific to the 8K x 18 configuration. The 'LA' suffix typically denotes low-power or specific speed grade variations within the product line. It is distinct from asynchronous FIFOs like the 72V85 series.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Designers should consult Renesas for current alternatives or evaluate cross-reference options based on pin compatibility and electrical specifications.
