72825LB10BG8

FIFOs Memory Overview

The Renesas Electronics Corporation 72825LB10BG8 is a dual synchronous first-in, first-out (FIFO) memory device. It integrates two independent 1K x 18 FIFOs within a single package, providing a total storage capacity of 36 kilobits. The component operates at a maximum clock frequency of 100 MHz and supports both single-clock and asynchronous dual-clock configurations for flexible data buffering. It utilizes a 121-pin Plastic Ball Grid Array (PBGA) package with a 1.27 mm pitch. The device functions on a 5.0 V supply voltage and features programmable Almost Empty, Almost Full, Half Full, and standard Empty/Full flags to manage data flow effectively.

FIFOs Memory Feature Summary

• Integrates two independent 1K x 18 FIFOs in a single package

FIFOs Memory Procurement Notes

This specific part number is listed as obsolete and discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or identifying valid replacement components from the same family. Ensure that any substitute parts maintain compatibility with the 121-pin PBGA footprint and 100 MHz synchronous interface requirements.

FIFOs Memory Selection Notes

Select this component when designing systems requiring high-speed buffering between parallel data paths of different widths or speeds. It is suitable for applications needing depth expansion up to 8,192 words per package or width expansion to 36 bits. Consider the 121-pin PBGA package constraints and the requirement for a 5.0 V power supply during system architecture planning.

FIFOs Memory Part Context

The 72825LB10BG8 belongs to the IDT 72825L DualSync FIFO series. This series is designed for high-performance data buffering needs, offering functionality equivalent to two separate 72225 FIFOs. The 'LB' suffix typically denotes lead-free construction, while 'BG8' indicates the specific 121-pin PBGA package configuration with reel packaging.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers include 72825LB10PFG and 72825LB15BG. Verify pinout compatibility and package dimensions before substitution.
