MPC7410HX450LE

Overview

The MPC7410HX450LE is a PowerPC RISC microprocessor implementing the fourth-generation G4 architecture. It features AltiVec technology, dual integer units, and a double-precision floating-point unit. The processor includes an integrated L2 cache controller supporting up to 2-Mbyte external SRAMs with configurable direct-mapped modes. It utilizes a 60x-compatible MPX bus interface with selectable I/O voltages of 1.8 V, 2.5 V, or 3.3 V. The device operates at a core frequency of 450 MHz with a maximum bus frequency of 133 MHz.

Feature Summary

• Implements full PowerPC 32-bit architecture with AltiVec SIMD instruction set
• Includes hardware-based multiprocessing capability with five-state cache coherency protocol
• Features improved floating-point unit with equal latency for single- and double-precision operations
• Supports configurable direct-mapped SRAM in the L2 cache interface

Applications

• Network infrastructure processing such as echo suppression devices
• Base station signal processing
• Real-time MPEG-2 decoding and digital video processing
• Continuous speech recognition systems

Procurement Notes

Verify that the ordering suffix 'LE' corresponds to Rev 1.4 or later specifications, which support 3.3 V system bus operation. Confirm input threshold configuration via BVSEL and L2VSEL pins matches the target board voltage levels. Ensure thermal management solutions account for the specific package type and junction-to-ambient resistance values provided in the datasheet.

Selection Notes

Select this component when high-performance vector processing is required alongside standard RISC execution. Consider the optional high-bandwidth MPX bus interface for memory-intensive applications. Evaluate power consumption requirements against the specified doze, nap, and sleep modes. Verify compatibility with existing 60x processor interface designs if migrating from previous generations.

Part Context

The MPC7410 represents the second implementation of Freescale's fourth-generation G4 microprocessors. It builds upon the MPC750 by adding AltiVec technology and significant memory subsystem bandwidth improvements. Compared to the MPC7400, it introduces configurable direct-mapped SRAM capabilities and removes 3.3-V I/O support on the L2 cache interface while maintaining mode compatibility with the 60x processor interface.
