NXP Semiconductors MPC7410THX500LE

Overview

MPC7410THX500LE from Freescale Semiconductor is a 500 MHz PowerPC G4 RISC microprocessor implementing the full 32-bit PowerPC architecture with AltiVec™ SIMD engine, 32 KB L1 instruction and data caches, and support for external 512 KB–2 MB two-way set-associative L2 cache. It targets high-performance embedded computing, digital signal processing, and network infrastructure applications requiring hardware-accelerated vector operations.

For engineers reviewing the MPC7410THX500LE datasheet, MPC7410THX500LE pinout, MPC7410THX500LE application, or MPC7410THX500LE equivalent, key selection considerations include its 500 MHz core frequency at 1.8 V core supply, 360-ball CBGA package, AltiVec-enabled parallel integer/floating-point execution, MPX bus interface compatibility with 60x processors, and thermal design requirements for sustained operation up to 105°C junction temperature.

Technical Context

The MPC7410THX500LE implements a superscalar, out-of-order execution pipeline with dual fixed-point units (FXU1/FXU2), a three-stage floating-point unit supporting IEEE 754 single/double precision in three-cycle latency, and a dedicated 128-bit AltiVec unit comprising permute and ALU subunits with 32-entry vector register file. Its memory subsystem includes nonblocking 32 KB L1 caches (eight-way set-associative, 32-byte lines) and an external L2 cache interface supporting 32/64/128-byte sectored line sizes and configurable direct-mapped SRAM mode.

It features a five-state cache coherency protocol (MESI + shared intervention), hardware TLB reload with 128-entry instruction/data TLBs, and a 32-bit address / 64-bit data MPX bus interface compatible with 60x architecture. Core-to-bus frequency multipliers range from 2× to 9×, and I/O voltage options include 1.8 V, 2.5 V, and 3.3 V (processor bus only), selected via BVSEL/L2VSEL pins sampled at HRESET negation.

FAQ

What is the maximum guaranteed operating frequency of the MPC7410THX500LE?

The MPC7410THX500LE is binned and tested to guarantee stable operation at 500 MHz under recommended conditions: 1.8 V ±100 mV core supply, junction temperature ≤105°C, and SYSCLK input within 33–133 MHz range. This rating is confirmed by Freescale's functional sorting process and AC timing validation per Table 7 in the Hardware Specifications document.

Does the MPC7410THX500LE support hardware multiprocessing?

Yes, the MPC7410THX500LE implements full hardware-based symmetric multiprocessing capability, including a five-state cache coherency protocol (MESI plus shared intervention) that eliminates software cache-coherency management overhead. This allows multiple MPC7410THX500LE processors to share memory coherently in tightly coupled systems without explicit cache flush instructions.

What L2 cache configurations does the MPC7410THX500LE support?

The MPC7410THX500LE supports external two-way set-associative L2 caches of 512 KB, 1 MB, or 2 MB capacity with sectored line sizes of 32, 64, or 128 bytes respectively. It also supports configurable direct-mapped SRAM mode for 256 KB, 512 KB, 1 MB, or 2 MB - enabling deterministic latency for time-critical applications where cache arbitration must be avoided.

How is I/O voltage selection configured on the MPC7410THX500LE?

I/O voltage thresholds for the processor bus (OVDD) and L2 bus (L2OVDD) are selected by sampling BVSEL and L2VSEL pin states at HRESET negation. BVSEL = ¬HRESET configures 3.3 V OVDD; BVSEL = HRESET selects 2.5 V; BVSEL = 0 selects 1.8 V. L2VSEL similarly selects 1.8 V or 2.5 V for L2OVDD. These settings are latched and cannot change during operation.

What thermal management guidance applies to the MPC7410THX500LE in full-on mode?

In full-on mode at 500 MHz, the MPC7410THX500LE dissipates up to 11.9 W (maximum). With its 360-ball CBGA package and RθJA = 18°C/W (natural convection), ambient temperature must remain ≤87°C to maintain Tj ≤105°C. Forced airflow (2 m/sec) reduces RθJA to 13°C/W, permitting higher ambient operation. Thermal interface material and copper pour area on the PCB are critical for reliable heat transfer to the heatsink.
