72215LB25TF

Overview

The Renesas Electronics Corporation 72215LB25TF is a synchronous FIFO memory device featuring an 18-bit data bus width and a storage capacity of 9K bits, organized as 512 x 18. It operates within a supply voltage range of 4.5 V to 5.5 V with a maximum supply current of 60 mA. The component supports unidirectional data transfer at a clock frequency of up to 40 MHz and achieves an access time of 25 ns. It is housed in a 64-pin TQFP surface-mount package and is rated for operation across a temperature range of 0°C to 70°C.

Feature Summary

• Provides synchronized first-in, first-out buffering for high-speed data streams
• Supports unidirectional data flow with dedicated read and write control signals
• Integrates programmable status flags for full and empty conditions

Applications

• Data buffering in local area network interfaces
• Interprocessor communication link management
• Graphics system data handling

Procurement Notes

Verify the exact suffix against official documentation, as standard listings often reference the PLCC variant (72215LB25J). Confirm lead-free compliance status, as many units in this series are non-RoHS. Check for end-of-life notices or discontinuation updates from Renesas before finalizing procurement plans.

Selection Notes

Select this model when a 5V logic interface is required for 18-bit wide data paths. Ensure the design accommodates the specific 25 ns access time and 40 MHz operational limit. Verify that the available package types align with the board layout requirements, noting potential variations between TQFP and PLCC options.

Part Context

This component belongs to the IDT 72215LB25 family of synchronous FIFOs. These devices are designed for applications requiring temporary data storage between asynchronous or differently clocked systems. The part number indicates a 512x18 organization with a 25 ns speed grade.
