7201LA12JI8

Overview

The Renesas 7201LA12JI8 is an asynchronous FIFO memory device with a capacity of 512 x 9 bits, housed in a 32-PLCC package. It supports bi-directional data transfer and operates at a maximum clock frequency of 50MHz with a 12ns access time. The component functions within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. Designed for industrial applications, it maintains reliable performance across a temperature range of 0°C to 70°C.

Feature Summary

• Supports bidirectional data flow for flexible system integration
• Provides high-speed asynchronous operation up to 50MHz
• Features low power consumption CMOS technology
• Includes relay capability for signal buffering

Applications

• High-speed data buffering between disparate clock domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring temporary storage
• Industrial control network interfaces

Procurement Notes

Verify the specific suffix 'JI8' corresponds to the 32-pin PLCC package variant when sourcing. Confirm RoHS compliance status as manufacturing processes may evolve. Check for end-of-life notices or alternative package recommendations from Renesas. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when bidirectional data transfer is required within a single FIFO block. The 512x9 organization suits applications needing moderate depth with 9-bit word widths. The 12ns speed class balances performance and power dissipation. Consider the PLCC package constraints regarding PCB layout and thermal management compared to surface-mount alternatives.

Part Context

This part belongs to the IDT 7201L series of asynchronous FIFOs, widely used in digital logic design. The 7201LA12 variant specifically denotes the 12ns speed grade. Renesas acquired the IDT product line, maintaining these legacy specifications for compatibility with existing designs.

Replacement Considerations

Direct substitutes include the 7201LA12JG (PLCC-32) and 7201LA12SOG8 (SOIC-28). Verify pinout compatibility before substitution. Package changes require schematic review.
