72211L25J

Overview

The Renesas 72211L25J is a synchronous First-In, First-Out (FIFO) memory device organized as 512 words by 9 bits. It operates with a maximum data rate of 40 MHz and features a typical access time of 15 ns. The component supports a supply voltage range from 4.5 V to 5.5 V and draws a maximum supply current of 35 mA. Designed for industrial reliability, it functions within an operating temperature range of 0°C to +70°C. The integrated circuit is housed in a 32-pin Thin Quad Flat Package (TQFP) with a 7 mm x 7 mm footprint.

Feature Summary

• Supports unidirectional data transfer via dedicated read and write clock controls
• Provides 9-bit input and output ports for parallel data handling
• Enables single-clock or dual-clock operation modes

Applications

• Graphics data buffering
• Local area network communication interfaces
• Interprocessor communication systems

Procurement Notes

Verify the specific suffix J against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Check for active production status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 512x9 synchronous FIFO architecture is required for 5V logic systems. Ensure the design accommodates the 4.5V to 5.5V supply range and the 0°C to +70°C commercial temperature limits. Verify that the 32-pin TQFP package fits the available PCB real estate constraints.

Part Context

This part belongs to the 7200 series of FIFO memories manufactured by Renesas Electronics. The series includes various densities and speeds tailored for high-speed data buffering applications. The 72211 variant specifically targets 512-word depth requirements within the broader family of parallel FIFO solutions.

Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Generic replacements may differ in timing characteristics or pin configurations.
