7202LA25JI

Overview

The Renesas Electronics Corporation 7202LA25JI is an asynchronous FIFO memory device belonging to the 7202L series. It features a storage organization of 1K x 9 bits, providing a total capacity of 9 kbit. The component supports bidirectional data transfer with a maximum clock frequency of 28.5 MHz and a typical access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 60 mA. The device is housed in a PLCC-32 package and is rated for industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Bidirectional bus orientation supports versatile data routing configurations.
• CMOS technology ensures low power consumption relative to older bipolar implementations.

Applications

• Buffering data streams between microprocessors and peripheral devices
• Synchronizing data transfers across different clock domains
• Temporary storage in high-speed digital signal processing chains

Procurement Notes

Verify the specific suffix 'JI' against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Ensure the required operating temperature range aligns with your system's environmental constraints. Confirm RoHS compliance status as indicated in the latest datasheet revision. Validate that the PLCC-32 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 1K x 9 asynchronous FIFO with bidirectional data capability is required. The 25 ns access time suits moderate-speed applications. Consider the 4.5 V to 5.5 V supply requirement for logic level compatibility. Evaluate the PLCC-32 package availability against surface-mount or through-hole assembly preferences. Compare performance metrics against alternative parts if higher speeds or different organizations are needed.

Part Context

The 7202L series represents Renesas' CMOS asynchronous FIFO family, designed for general-purpose buffering. This part number specifically denotes the 1K x 9 configuration with 25 ns speed grade. The 'J' indicates the PLCC package type, while 'I' specifies the industrial temperature range. This series provides a cost-effective solution for bridging timing mismatches in digital systems.

Replacement Considerations

Check for direct substitutes within the 7202L series with differing speed grades or organizations. Verify cross-brand equivalents such as IDT or Cypress parts with matching 1Kx9 async specifications. Ensure any replacement maintains the same PLCC-32 footprint and 4.5V-5.5V supply requirements.
