7201LA50J8

Overview

The Renesas Electronics Corporation 7201LA50J8 is an asynchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 x 9. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a data rate of 15 MHz. The component features Full and Empty flags for data flow control and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous first-in/first-out memory architecture
• Dual-port configuration for independent read/write operations
• Hardware-based Full and Empty status flag generation

Applications

• Data buffering between disparate clock domains
• Interface bridging in communication systems
• Temporary data storage in digital signal processing chains

Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against specific project standards, noting that older variants may not meet current environmental directives. Validate package integrity upon receipt due to potential long-term storage conditions.

Selection Notes

Select this component when a 512-word by 9-bit asynchronous buffer is required. Ensure system timing aligns with the 15 MHz maximum data rate specification. Verify that the 32-PLCC surface mount package fits the target PCB footprint and assembly capabilities.

Part Context

This device belongs to the 7201 series of CMOS parallel FIFO memories manufactured by Renesas Electronics. It serves as a specialized memory interface solution for applications requiring reliable data transfer without shared clock synchronization between input and output ports.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify electrical parameter compatibility if considering cross-manufacturer alternatives.
