72245LB10PFI8

Overview

The Renesas Electronics Corporation 72245LB10PFI8 is a synchronous FIFO memory device with a capacity of 4K x 18 bits. It operates at a data rate of 100MHz and features a 6.5ns access time. The component supports bidirectional data bus operation and is powered by a voltage range of 4.5V to 5.5V. It is housed in a 64-LQFP package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed synchronous data buffering with 100MHz clock rates
• Provides programmable status flags for precise buffer management
• Enables system expansion through depth and width configuration options

Applications

• High-speed data buffering in telecommunications systems
• Interface bridging between asynchronous logic blocks
• Data acquisition systems requiring precise timing control

Procurement Notes

Verify component authenticity due to obsolete status. Confirm package integrity as moisture sensitivity remains active. Check for valid RoHS exemption documentation if required by current manufacturing standards. Ensure supplier provides traceability records consistent with original Renesas specifications.

Selection Notes

Select this component when bidirectional data transfer is required alongside synchronous timing constraints. Compare against unidirectional variants like the 72245LB10J8 if directionality differs from design needs. Evaluate pin compatibility with existing 64-pin footprints before integration into new designs.

Part Context

Part of the 7200 series synchronous FIFO family, designed for high-performance memory applications. Shares architectural similarities with other 72245 variants but distinguishes itself through bidirectional bus support and specific package configuration. Serves as a legacy solution for systems requiring reliable data synchronization.

Replacement Considerations

Consider IDT72245LB10PFI8 as a direct equivalent under former branding. Verify functional parity with 72245LB10TF8 regarding package dimensions and electrical characteristics before substitution.
