NXP Semiconductors MPC7410VS500LE

Overview

MPC7410VS500LE 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, integrated L2 cache controller, and MPX bus interface. It operates at 1.8 V core voltage, supports 32-bit address/64-bit data system bus, and targets high-performance embedded computing, digital signal processing, and network infrastructure applications.

For engineers reviewing the MPC7410VS500LE datasheet, MPC7410VS500LE pinout, MPC7410VS500LE application, or MPC7410VS500LE equivalent, key selection criteria include confirmed 500 MHz core frequency, AltiVec-enabled vector processing capability, L2 cache interface configurability (1–2 MB, 32/64/128-byte line), 360-ball CBGA package thermal resistance (RθJMA = 18°C/W), and support for doze/nap/sleep power management modes.

Technical Context

The MPC7410VS500LE implements a five-stage scalar pipeline (fetch, decode/dispatch, execute, complete/writeback) with out-of-order execution, eight-entry completion queue, and dual-issue dispatch to eight independent execution units-including FXU1/FXU2, FP unit, AltiVec permute/ALU, and branch unit. Its AltiVec unit features full 128-bit datapaths, dedicated 32-entry vector register file, and hardware-pipelined VSIU/VCIU/VFPU subunits.

It integrates a 32 KB iL1 and 32 KB dL1 cache (eight-way set-associative, 32-byte lines), nonblocking design with hits-under-misses, and an external L2 interface supporting 512 KB–2 MB two-way set-associative SRAM with configurable direct-mapped mode. The MPX bus extension provides mode-compatible 60x interface with 32-bit address/64-bit data width and bus-to-core multipliers up to 9×.

FAQ

What is the guaranteed maximum operating frequency of the MPC7410VS500LE?

The MPC7410VS500LE is binned and tested to guarantee stable operation at 500 MHz core frequency under specified conditions: VDD = 1.8 V ± 100 mV, junction temperature ≤105°C, and SYSCLK between 33–133 MHz. This rating is validated per Freescale's AC electrical specifications (Table 7) and reflects worst-case silicon at maximum thermal load. The MPC7410VS500LE achieves this via optimized PLL configuration and 0.18 µm process tuning.

Does the MPC7410VS500LE include on-die L2 cache?

No, the MPC7410VS500LE does not integrate L2 cache on-die. It features an external L2 cache interface supporting 512 KB–2 MB off-chip SRAM with configurable line sizes (32/64/128 bytes) and two-way set-associative or direct-mapped modes. The MPC7410VS500LE contains only L1 instruction and data caches (32 KB each) and an integrated L2 cache controller. External L2 implementation allows system designers to optimize capacity, latency, and cost per application.

What power management modes does the MPC7410VS500LE support?

The MPC7410VS500LE supports three hardware-controlled low-power states: Doze (core clocks gated, bus active), Nap (core and bus clocks gated, memory retained), and Sleep (all clocks stopped, PLL/DLL disabled). In Sleep mode, typical power drops to 600 mW; maximum is 1.1 W. These modes are entered via specific SPR writes and are essential for thermal management in fanless enclosures. The MPC7410VS500LE implements these without external logic, using on-chip power gating and voltage regulation controls.

How is I/O voltage configured on the MPC7410VS500LE?

I/O voltage thresholds for the processor bus (OVDD) and L2 bus (L2OVDD) are configured at reset by sampling BVSEL and L2VSEL pin states relative to HRESET. BVSEL = 0 selects 1.8 V, BVSEL = HRESET selects 2.5 V, and BVSEL = ¬HRESET selects 3.3 V. The MPC7410VS500LE requires corresponding OVDD/L2OVDD supply voltages to match selected thresholds-mismatch causes undefined behavior. Configuration is latched at HRESET negation and cannot be changed dynamically.

Is the MPC7410VS500LE pin-compatible with other MPC74xx devices?

The MPC7410VS500LE uses a 360-ball CBGA package identical to MPC7400/MPC7410 variants, but pin functions differ significantly due to AltiVec additions, L2 interface enhancements, and updated power domains. While mechanical footprint matches, signal mapping (e.g., new L2ASPARE pin, redefined cache control signals) and voltage domain assignments require PCB redesign. Therefore, the MPC7410VS500LE is not a drop-in replacement for earlier MPC74xx parts despite shared packaging.
