7202LA12JI8

Overview

The Renesas 7202LA12JI8 is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates at a maximum data rate of 50MHz with a typical access time of 12ns. The component supports unidirectional bus communication and functions within a supply voltage range of 4.5V to 5.5V. It is housed in a 32-PLCC package measuring 14x11.46mm and is rated for industrial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes auto-retransmit capability to reset the read pointer upon pulse
• Provides status flags including Empty, Half-Full, and Full indicators
• Allows expansion by both word depth and bit width

Applications

• Multiprocessing systems requiring data buffering
• Rate matching applications between different clock domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify the specific suffix 'JI8' against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level. Ensure the ordering information matches the exact package type and temperature grade required for your design. Cross-reference with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when a 1K x 9 asynchronous FIFO is required with 12ns access speed. Consider the 32-PLCC package constraints and 5V logic compatibility. Evaluate if the unidirectional interface meets system requirements compared to bidirectional alternatives in the 7202L series.

Part Context

This part belongs to the Renesas 7202L series of high-speed CMOS asynchronous FIFOs. The series is known for low power consumption and full expandability. It serves as a direct replacement for legacy IDT 7202 devices, maintaining functional compatibility while offering modern manufacturing standards.

Replacement Considerations

The IDT7202LA12JGI8 is a confirmed equivalent part number from Integrated Device Technology. Verify that the substitute maintains the same PLCC-32 package and electrical specifications before implementation.
