TW3801-TC1-CR

Specialized Overview

The TW3801-TC1-CR is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed primarily for security system applications. It supports MII and RMII network interfaces to facilitate data communication within secure environments. The device operates on dual voltage supplies of 1.8V and 3.3V, ensuring compatibility with various logic levels in embedded systems. It is housed in a 100-TQFP package with dimensions of 12x12 mm, suitable for surface mount installation. This component represents the standard tray packaging variant of the TW3801 series, distinct from the CRT version which utilizes tube packaging.

Specialized Feature Summary

• Supports MII and RMII Ethernet interfaces for secure system connectivity
• Operates with 1.8V and 3.3V power supplies
• Housed in a 100-TQFP surface-mount package

Specialized Applications

• Security systems requiring dedicated network interface capabilities

Specialized Procurement Notes

Verify the specific suffix requirement during procurement, as the CR designation indicates tray packaging while other variants may use tubes. Confirm end-of-life status and lead times through authorized distributors, as availability may be limited due to product lifecycle management. Ensure compatibility with existing 1.8V and 3.3V power rails in the target design before finalizing orders.

Specialized Selection Notes

Select the TW3801-TC1-CR when a 100-pin TQFP interface solution is required for security applications. Compare against the TC1-CRT variant if tube packaging is preferred for assembly processes. Verify that the MII/RMII interface requirements align with the system's network topology. Consider the discontinued status and plan for long-term supply chain stability or alternative sourcing strategies.

Specialized Part Context

The TW3801 series belongs to Renesas' portfolio of specialized interface ICs tailored for security and access control systems. The TW3801-TC1-CR specifically denotes the tray-packaged version of this component. It serves as a critical link between the host processor and network infrastructure in secure environments, providing reliable data transmission via standard Ethernet interfaces.

Specialized Replacement Considerations

The TW3801-TC1-CR is listed as obsolete. The TW3801-TC1-CR is noted as an available alternative packaging option in some contexts, but generally, designers should consult Renesas for current replacement recommendations or equivalent components from other manufacturers that support MII/RMII interfaces in similar packages.
