WP34C2R4NFEI-400B2

Overview

The WP34C2R4NFEI-400B2 is a specialized network processor from the WinPath3 family, manufactured by Microchip Technology. It operates at a clock frequency of 400 MHz and features lead-free solder balls with Pb-free bump technology. The component is housed in an 896-pin B1BGA package, designed for surface mount (SMD/SMT) installation. It supports a wide operating temperature range from -40°C to +85°C and exhibits moisture sensitivity. This integrated circuit combines control plane and enhanced data plane processing capabilities within a single compact form factor.

Feature Summary

• Integrates control plane and enhanced data plane processing components
• Utilizes two high-performance MIPS 34K multithreaded processors for control plane operations
• Supports surface mount installation via an 896-pin B1BGA package

Applications

• Network controller applications requiring dedicated processing
• Embedded systems utilizing MIPS architecture
• Specialized application processors for communication infrastructure

Procurement Notes

Verify the specific suffix B2 corresponds to the required lead-free ball and Pb-free bump configuration as documented. Confirm the 896-pin B1BGA package dimensions match the target PCB footprint. Ensure thermal management solutions accommodate the -40°C to +85°C operating range. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this model when dual MIPS 34K cores are required for network control tasks. Consider the 400 MHz operational speed for performance needs. Evaluate the B1BGA-896 package for space constraints and thermal dissipation. Compare against other WinPath3 variants like WP33 or WP32 series if different core counts or frequencies are needed.
