MPC7410HX400LE

Overview

The MPC7410HX400LE is a PowerPC G4 RISC microprocessor manufactured by NXP (formerly Freescale). It operates at a core frequency of 400 MHz with a 3.3 V processor bus interface voltage. The device utilizes a 0.18 µm CMOS process and features AltiVec technology, an eight-entry completion queue, and hardware multiprocessing support. It supports selectable I/O voltages of 1.8 V, 2.5 V, or 3.3 V via configuration pins.

Feature Summary

• Implements the full PowerPC 32-bit architecture with AltiVec SIMD capabilities
• Features a high-bandwidth MPX bus interface compatible with the 60x processor standard
• Includes configurable direct-mapped SRAM capability within the L2 cache interface
• Provides full hardware-based multiprocessing with a five-state cache coherency protocol

Applications

• High-performance computing systems
• Embedded network infrastructure equipment
• Industrial control applications requiring robust processing

Procurement Notes

Verify that the specific ordering suffix matches the required bus voltage and thermal package. Confirm compatibility with existing system power rails for the 3.3 V processor interface. Ensure design adheres to the absolute maximum ratings for supply voltages during power-on sequences to prevent permanent damage.

Selection Notes

Select this component when a 400 MHz PowerPC G4 core is required with a 3.3 V system bus. Evaluate thermal management requirements based on the specified junction-to-ambient resistance values. Consider the availability of 360-pin CBGA or HCTE packages for the target PCB layout constraints.

Part Context

This part belongs to the MPC7410xxnnnNE series, representing the second implementation of the fourth-generation G4 microprocessors. It succeeds earlier models like the MPC750 by adding AltiVec technology and improved memory subsystem bandwidth while maintaining mode compatibility with the 60x processor interface.

FAQ

How is the processor bus input threshold voltage selected?

The input threshold is determined by the state of the BVSEL signal sampled at negation of HRESET. Setting BVSEL to logic 1 selects the 3.3 V threshold.

What is the supported range for the SYSCLK frequency?

The SYSCLK frequency ranges from 33 MHz to 133 MHz, depending on the PLL_CFG settings and the resulting core-to-bus frequency multiplier.
