72211L25J8

Overview

The Renesas Electronics Corporation 72211L25J8 is a synchronous FIFO memory IC with a capacity of 4.5K bits, organized as 512 words by 9 bits. It operates at a maximum data rate of 40MHz with a 15ns access time. The device supports unidirectional data flow and functions within a supply voltage range of 4.5V to 5.5V. It is housed in a 32-PLCC package (14x11.46mm) and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with independent read and write clocks
• Dual-port zero fall-through time architecture
• Empty and full flags signal FIFO status

Applications

• Data buffering between asynchronous systems
• Clock domain crossing applications
• High-speed data acquisition systems

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against project specifications, as this specific part may not meet current environmental standards. Validate package dimensions and pinout compatibility during integration planning.

Selection Notes

Select this component for applications requiring synchronous FIFO functionality with zero latency. Ensure system clock frequencies remain within the specified 40MHz limit. Verify that the 32-PLCC surface mount package fits the available PCB real estate and thermal constraints.

Part Context

This part belongs to the 72211 series of synchronous FIFOs from Renesas. It shares architectural similarities with other members like the 72211L15J8 but differs in speed grade. The series is designed for high-performance buffering needs in digital logic circuits.
