72211L25JG

Overview

The Renesas 72211L25JG is a synchronous First-In, First-Out (FIFO) memory device with an organization of 512 x 9 bits. It operates on a single 5V power supply within the range of 4.5V to 5.5V. The component supports unidirectional data transfer with a maximum clock frequency of 40MHz and features a typical access time of 15ns. Designed for surface-mount applications, it is housed in a 32-pin TQFP package measuring 7x7mm. The device functions reliably across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Synchronous FIFO architecture with dedicated read and write clock controls
• Supports both single-clock and dual-clock asynchronous operation modes
• Integrated programmable flags for status monitoring
• 9-bit wide input and output data ports

Applications

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

Procurement Notes

Verify the specific suffix JG against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for any product discontinuance notices or lifecycle changes that may affect long-term availability. Ensure design-in validation matches the 5V logic family specifications.

Selection Notes

Select this component when a 5V synchronous FIFO with 512x9 depth is required for data buffering between processors or peripherals. It is suitable for designs needing independent read and write clock domains or a shared clock source. Consider alternative voltage variants if system power rails differ from the standard 5V specification.

Part Context

This part belongs to the Renesas 7200 series of high-speed FIFO memories. The series includes various density and voltage options tailored for different interface speeds and logic families. The 72211 variant specifically targets 5V applications requiring moderate buffer depths for reliable data synchronization in digital systems.

Replacement Considerations

Direct replacements include other 5V synchronous FIFOs with identical 512x9 organization and 32-pin TQFP packaging. Verify timing parameters and flag functionality compatibility before substitution.
