72825LB10BG

FIFOs Memory Overview

The Renesas Electronics Corporation 72825LB10BG is a synchronous dual First-In, First-Out (FIFO) memory device. It integrates two independent 1K x 18 FIFOs within a single package, providing a total capacity of 36 kilobits. The component operates on a 5.0V supply voltage with a specified range of 4.5V to 5.5V. It utilizes a 121-pin Plastic Ball Grid Array (PBGA) package. The device supports both single-clock and asynchronous dual-clock operations for flexible data buffering applications.

FIFOs Memory Feature Summary

• Integrates two independent 1K x 18 FIFOs in a single package
• Supports asynchronous or coincident read and write clock operations
• Provides dedicated control, data, and flag lines for each FIFO
• Features programmable almost empty and almost full flags

FIFOs Memory Applications

• Optical disk controllers
• Local Area Networks (LANs)
• Interprocessor communication
• Network switching

FIFOs Memory Procurement Notes

Verify the current lifecycle status before procurement as this component may be obsolete. Confirm package availability and lead times with authorized distributors. Ensure design compatibility with the 121-pin PBGA footprint and 5.0V logic levels. Check for moisture sensitivity handling requirements during storage and assembly.

FIFOs Memory Selection Notes

Select this component when dual independent 18-bit wide FIFOs are required in a compact form factor. Consider the 121-pin PBGA package for high-density board layouts. Verify that the 5.0V operating voltage aligns with the system power rails. Evaluate the need for asynchronous clocking capabilities versus single-clock synchronization.

FIFOs Memory Part Context

This part belongs to the 72825L series of synchronous dual FIFOs manufactured by Renesas Electronics. It is functionally equivalent to two separate 72225 FIFOs combined into one unit. The series is designed for high-speed data buffering and interface matching between different data bus widths.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify if alternative packages like TQFP offer similar functionality. Ensure any replacement maintains the 1K x 18 organization and 5.0V operation.
