7204L12JG8

Overview

The Renesas Electronics Corporation 7204L12JG8 is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 36K bits, organized as 4K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 50 MHz with a maximum access time of 12 ns. The component utilizes a 32-PLCC surface-mount package and functions at temperatures between 0°C and 70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Supports unidirectional bus directionality
• Includes relay capability for signal buffering

Applications

• Data buffering in high-speed digital systems
• Clock domain crossing interfaces
• Parallel data transfer applications

Procurement Notes

Verify the specific suffix JG8 against official datasheets to confirm package type and RoHS compliance status. Confirm current availability through authorized channels as distribution status may vary. Ensure compatibility with existing system voltage requirements of 4.5 V to 5.5 V before procurement.

Selection Notes

Select this component when a 4K x 9 asynchronous FIFO with 12 ns access time is required. It is suitable for designs needing 50 MHz performance in a 32-pin PLCC package. Consider alternatives if lower speed or different organization is needed.

Part Context

Part of the 7200 series of FIFO memories from Renesas. This series provides various speeds and organizations for parallel data handling. The 7204L12JG8 specifically targets applications requiring moderate speed and standard CMOS logic levels.

Replacement Considerations

The 7204L35J8 is listed as an obsolete product with the 7204L12JG8 identified as an upgrade substitute. Verify functional equivalence and pinout compatibility before replacement.
