7204L25JI

Overview

The Renesas Electronics Corporation 7204L25JI is an asynchronous FIFO memory device featuring a 4K x 9 organization and 36 kbit storage capacity. It operates with a maximum clock frequency of 28.5 MHz and a 25 ns access time. The component supports bidirectional data buses and functions within a supply voltage range of 4.5 V to 5.5 V, drawing up to 120 mA. Designed for industrial environments, it withstands temperatures from -40°C to +85°C. The integrated circuit is housed in a 32-PLCC surface-mount package.

Feature Summary

• Asynchronous operation for flexible interface timing
• Bidirectional data bus support for versatile connectivity
• Industrial-grade temperature rating for harsh environments

Applications

• Data buffering between disparate system speeds
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix requirements against current manufacturer documentation, as legacy components often have variant specifications. Confirm end-of-life status and obsolescence notices prior to integration. Ensure compatibility with existing 5V logic levels and PLCC footprint constraints during design validation.

Selection Notes

Select this component when bidirectional data transfer is required alongside asynchronous control signals. The 4K depth suits moderate buffering needs without excessive latency. Verify that the 5V operating voltage aligns with the target system power rails and that the PLCC package fits the available board space.

Part Context

Part of the 7204 series, this device represents a specialized memory solution for parallel data handling. It complements unidirectional variants by offering two-way data flow capabilities. The series targets applications requiring reliable, low-latency temporary storage in industrial and commercial electronic systems.
