72225LB25PF8

Overview

The Renesas Electronics Corporation 72225LB25PF8 is a synchronous FIFO memory integrated circuit belonging to the 7200 series. It provides a storage capacity of 18K bits, organized as 1K words by 18 bits. The device supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The component is housed in a 64-TQFP (14x14) surface-mount package and is rated for an industrial operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation supporting high-speed data buffering
• Configurable programmable status flags for full and empty conditions
• Wide 18-bit data bus width for efficient parallel data handling

Applications

• High-speed data buffering in telecommunications systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt to ensure suitability for automated surface-mount assembly processes.

Selection Notes

Select this component when 18-bit wide synchronous FIFO buffering is required. Ensure the design accommodates the 4.5V to 5.5V supply voltage range. Consider the 64-TQFP footprint constraints during PCB layout planning.
