72251L15JGI

Overview

The Renesas 72251L15JGI is a synchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 66.7 MHz. The component features a 10 ns access time and draws a maximum supply current of 50 mA. It is housed in a 32-PLCC package (14x11.46 mm) and functions over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Synchronous operation with unidirectional bus architecture for efficient data buffering
• Supports programmable status flags to manage data flow control
• Designed for high-speed interprocessor communication and rate matching applications

Applications

• Interprocessor communication systems
• Data buffering in graphics processing units
• Local area network interface buffers

Procurement Notes

Verify the obsolete status and End-of-Life notices before procurement planning. Confirm RoHS3 compliance and moisture sensitivity level requirements for your assembly process. Check for specific PCN documentation regarding label changes or assembly site updates to ensure supply chain continuity and regulatory adherence.

Selection Notes

Select this component when a 72K bit synchronous FIFO with 9-bit width is required. Ensure the design accommodates the 32-PLCC surface mount package dimensions. Verify that the system logic levels match the 5V TTL I/O specifications and that the operating temperature range aligns with environmental constraints.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories, which are designed for high-performance data buffering. The 72251 variant specifically offers 8K x 9 organization. It is functionally compatible with other devices in the IDT/Renesas 72xxx family, facilitating migration and system expansion while maintaining pin compatibility.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the 7200 series. Verify electrical parameter equivalence for any cross-referenced components.
