MPC7410THX400LE

Overview

The MPC7410THX400LE is a PowerPC G4 RISC microprocessor operating at a maximum core frequency of 400 MHz. It features a 32-bit architecture with AltiVec technology, 32 KB L1 instruction and data caches, and an external L2 cache interface supporting up to 2 MB. The device utilizes a 0.18 µm CMOS process with a 1.8 V core supply and supports selectable 1.8 V, 2.5 V, or 3.3 V I/O voltages. It operates within a junction temperature range of 0°C to 105°C.

Feature Summary

• Implements the full PowerPC 32-bit architecture with AltiVec vector processing capabilities.
• Features a high-performance out-of-order execution pipeline with hardware multiprocessing support.
• Includes configurable direct-mapped SRAM capability for the L2 cache interface.
• Supports MPX bus extension to the 60x processor interface with parity checking.

Applications

• Computing systems
• Embedded systems
• Industrial applications

Procurement Notes

Verify that the specific THX suffix corresponds to the extended industrial temperature range documentation rather than standard commercial specifications. Confirm the voltage select pin (BVSEL) configuration matches the target system's I/O levels, as this setting is latched during reset and cannot be changed during operation. Ensure the design accounts for the specific thermal resistance values associated with the CBGA package variant.

Selection Notes

Select this component when a high-performance embedded solution requires AltiVec acceleration and robust multiprocessing capabilities. Consider the available L2 cache interface options and the specific I/O voltage requirements of the host system. Evaluate the thermal management needs based on the 0.18 µm process power consumption characteristics and the required junction temperature limits for the deployment environment.

Part Context

This part belongs to the MPC7410 series, which represents the second implementation of Freescale's fourth-generation G4 microprocessors. It builds upon the MPC750 by adding AltiVec technology and improving memory subsystem bandwidth. The THX designation indicates a specific industrial-grade variant with verified performance and reliability characteristics for demanding environments.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material.

FAQ

How is the I/O voltage threshold selected?

The input voltage threshold for the processor bus is selected by sampling the BVSEL signal state at the negation of HRESET. This setting determines whether the interface operates at 1.8 V, 2.5 V, or 3.3 V.

What is the supported L2 cache size?

The MPC7410 supports internal L2 cache controllers with external data SRAMs, accommodating configurations of 512 Kbyte, 1 Mbyte, or 2 Mbyte.
