72225LB25JI8

Overview

The Renesas 72225LB25JI8 is a synchronous FIFO memory device with a capacity of 18K bits, organized as 1K words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 40 MHz with a maximum access time of 15 ns. The component features unidirectional bus direction and programmable flag support. It is housed in a 68-PLCC package and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with single clock domain control
• Programmable full and empty flags for status monitoring
• Wide 18-bit data bus width for high-throughput applications

Applications

• High-speed data buffering in telecommunications systems
• Interface bridging between asynchronous logic domains
• Data acquisition system temporary storage

Procurement Notes

Verify the specific suffix 'JI8' against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older variants may differ. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this part when 18-bit wide synchronous FIFO buffering is required. Ensure the 4.5V to 5.5V supply voltage aligns with the system design. Verify that the 68-PLCC package fits the PCB layout constraints and that the industrial temperature range meets environmental requirements.

Part Context

This component belongs to the IDT 722x5LB series of synchronous FIFOs. It provides non-volatile-like data retention during power cycles only if backed up, otherwise it functions as volatile static RAM. The series is designed for high-performance digital signal processing and communication interfaces requiring precise timing control.
