72215LB25J

Overview

The Renesas Electronics Corporation 72215LB25J is a synchronous FIFO memory device with a storage capacity of 9 kbit, organized as 512 x 18. It operates on a unidirectional bus and supports a maximum clock frequency of 40 MHz with an access time of 25 ns. The component requires a supply voltage between 4.5 V and 5.5 V, drawing a maximum supply current of 60 mA. It functions within a temperature range of 0°C to +70°C and is housed in a 68-PLCC package.

Feature Summary

• Synchronous first-in, first-out memory architecture for data buffering
• Unidirectional data bus interface supporting 18-bit word width
• Programmable flag support for status monitoring

Applications

• Data buffering in graphics systems
• Local area network communication interfaces
• Interprocessor communication links

Procurement Notes

Verify the obsolete status and end-of-life notices before procurement planning. Confirm RoHS compliance requirements as the product may not meet current environmental standards. Check for moisture sensitivity handling instructions during storage and assembly. Validate that the 68-PLCC package matches the target PCB footprint design specifications.

Selection Notes

Select this component when a 512 x 18 synchronous FIFO is required for unidirectional data transfer. Ensure the system design accommodates the 4.5 V to 5.5 V operating voltage range. Verify that the 40 MHz maximum clock speed meets the application timing requirements. Consider the 68-PLCC package constraints for surface mount assembly processes.

Part Context
