72211L10JGI

Overview

The Renesas 72211L10JGI is a synchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates at a maximum data rate of 100MHz with an access time of 6.5ns. The component supports unidirectional bus direction and is powered by a voltage supply ranging from 4.5V to 5.5V, with a maximum supply current of 35mA. It features programmable flags and is housed in a 32-PLCC package measuring 14x11.46mm. The device functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous first-in, first-out memory architecture with clocked read and write controls for reliable data buffering.
• Supports single-clock or dual-clock operation modes to accommodate varying system timing requirements.
• Includes programmable status flags to indicate full and empty conditions for flow control.

Applications

• Graphics data buffering
• Local area network interface buffering
• Interprocessor communication

Procurement Notes

Verify the specific suffix JGI against official Renesas documentation to confirm pinout and package dimensions match the 32-PLCC specification. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or obsolescence announcements on the manufacturer website. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when a 512x9 synchronous FIFO is required for 5V logic systems. Compare against the 72V211 series if a 3.3V operating voltage is necessary instead. Verify that the 100MHz speed meets the system's throughput requirements. Consider the PLCC package type for compatibility with existing board layouts.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. It is a 5.0V version of the broader 722x1 family. The series is designed for high-speed data buffering applications requiring deterministic latency. It serves as a bridge between asynchronous or different-speed digital components.

Replacement Considerations

The 72V211L10JGI is a 3.3V equivalent variant of this device. Verify voltage compatibility before substitution. Other members of the 722x1 family may offer different depths or speeds but require electrical verification.
