7201LA35J8

Overview

The 7201LA35J8 is an asynchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device operates with a maximum access time of 35 ns and supports data rates up to 22.2 MHz. It utilizes a uni-directional bus architecture and requires a supply voltage between 4.5 V and 5.5 V. The component is housed in a 32-PLCC package with J-leads, measuring 14 mm by 11.46 mm. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional data flow architecture
• High-speed data transfer capability up to 22.2 MHz

Applications

• Buffering data streams between asynchronous logic blocks
• Interface bridging between different speed domains in digital systems
• Data buffering in communication protocols requiring temporary storage

Procurement Notes

Verify the specific suffix and package variant against official Renesas documentation to ensure compatibility with existing board layouts. Confirm that the 32-PLCC footprint matches the design requirements. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the target market.

Selection Notes

Select this component when a small, high-speed asynchronous buffer is required for uni-directional data paths. The 512x9 organization suits applications needing moderate depth with 9-bit word widths. Consider the 35 ns access time for timing constraints. Evaluate the PLCC package suitability for surface mount assembly processes and thermal management requirements in the final enclosure.

Part Context

This part belongs to the 7200 series of asynchronous FIFOs from Renesas. It shares architectural similarities with other members like the 7208L35J8 but differs in organization and pin count. The series is designed for general-purpose memory buffering in embedded systems and industrial control applications where simple, reliable data staging is necessary without complex controller overhead.
