7208L25JI

Overview

The Renesas Electronics Corporation 7208L25JI is a CMOS parallel First-In-First-Out (FIFO) memory device with an organization of 64K x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 28.5 MHz with a 25 ns access time. The component is housed in a 32-pin PLCC package and supports asynchronous timing. This specific part number is identified as a discontinued product by the manufacturer.

Feature Summary

• Asynchronous FIFO architecture for buffering data between different clock domains
• CMOS technology ensuring low power consumption relative to older logic families
• Parallel interface supporting 9-bit wide data transfer

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between microprocessors and peripheral devices
• Temporary storage in communication protocol converters

Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity of existing stock, as RoHS compliance status is listed as non-compliant for this specific variant. Supply chain stability cannot be guaranteed through standard procurement channels.

Selection Notes

Designers requiring equivalent functionality should evaluate current generation FIFOs from the same family that offer updated packaging or compliance standards. Considerations must include verifying pin compatibility if replacing in existing footprints, though physical dimensions may vary across suffixes. Ensure that the selected replacement maintains the required 64K x 9 depth and 25 ns speed grade to preserve system timing integrity without redesigning the board layout.

Part Context

The 7208 series represents a line of high-density asynchronous FIFOs designed for versatile data handling applications. The 7208L25JI specifically denotes the 64K x 9 configuration within this family. These components were widely utilized in legacy industrial and telecommunications equipment where reliable parallel data buffering was critical. The 'L' suffix typically indicates the specific speed grade and voltage characteristics associated with this generation of CMOS logic.
