72211L10JGI8

Overview

The Renesas 72211L10JGI8 is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates on a supply voltage range of 4.5V to 5.5V with a maximum supply current of 35mA. The device features programmable flags for status monitoring and is housed in a 32-PLCC package measuring 14x11.46mm. It is designed for surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with independent read and write clock controls allows flexible timing management.
• Programmable flag outputs provide real-time status indication for full and empty conditions.
• Single-clock or dual-clock operation modes support various system synchronization requirements.

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the specific suffix JGI8 against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure the operating voltage matches the 4.5V to 5.5V requirement. Confirm the temperature grade corresponds to the commercial range. Cross-reference the part number with the latest datasheet revision to avoid obsolete variants.

Selection Notes

Select this component when a 512x9 synchronous FIFO is required for 100MHz applications. It is suitable for systems needing 3.3V or 5V logic compatibility within the specified voltage limits. Consider the PLCC package constraints for PCB layout. Evaluate if the 6.5ns access time meets the system latency requirements compared to faster asynchronous alternatives.

Part Context

This device is part of the Renesas 7200 series of high-speed FIFO memories. The series includes variants with different capacities and speeds, such as the 72201 and 72221 models. These components are designed for general-purpose data buffering and protocol conversion tasks in embedded systems and industrial applications.

Replacement Considerations

The 72V211L10PF is a 3.3V version of the 72211 device family. Verify voltage compatibility before substitution. Other members of the 7200 series may offer different depths or widths but share similar interface characteristics.
