72215LB15J8

Overview

The Renesas Electronics Corporation 72215LB15J8 is a synchronous First-In, First-Out (FIFO) memory device organized as 512 words by 18 bits. It operates with a maximum clock frequency of 66.7 MHz and features a 25 ns access time. The component supports a unidirectional data bus and functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 60 mA. It is housed in a PLCC-68 package and is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering
• Unidirectional data bus architecture supporting 18-bit word width
• High-speed performance capability up to 66.7 MHz clock frequency

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in telecommunications equipment

Procurement Notes

Verify the obsolete status and End-of-Life (EOL) notice before procurement planning. Confirm moisture sensitivity level requirements for handling and storage. Ensure compatibility with existing 5V logic levels and PLCC-68 footprint constraints. Check for available alternative sources or last-time buy options due to discontinuation.

Selection Notes

Select this component when a synchronous FIFO with 18-bit width and 512-depth is required. Compare against the 72215LB25 series if slower speeds are acceptable. Verify that the 5V supply requirement aligns with the system design. Consider the PLCC-68 package availability for PCB layout.

Part Context

This part belongs to the Renesas 72215 series of synchronous FIFOs. It shares architectural similarities with other members like the 72215LB25 but differs in speed grade. The series is designed for general-purpose data buffering applications requiring reliable synchronous transfer.
