NXP Semiconductors MC7410VU500LE

Overview

MC7410VU500LE from Freescale Semiconductor is a PowerPC G4-generation 32-bit RISC microprocessor with AltiVec SIMD engine, 500 MHz core frequency, 32 KB L1 instruction and 32 KB L1 data caches, and support for up to 2 MB external L2 cache. It implements full hardware multiprocessing with MESI+ coherency and targets high-performance embedded computing, digital media processing, and network infrastructure control planes.

For engineers reviewing the MC7410VU500LE datasheet, MC7410VU500LE pinout, MC7410VU500LE application, or MC7410VU500LE equivalent, this page delivers verified electrical specs, thermal limits, bus interface timing, L2 cache configuration options, and validated alternative processors for migration or second-sourcing in mission-critical PowerPC-based systems.

Technical Context

The MC7410VU500LE integrates a superscalar 7-stage pipeline with dual-issue dispatch to eight execution units (FXU1/FXU2, FPU, AltiVec permute/ALU, branch, load/store, system), supporting out-of-order execution and in-order completion via an 8-entry completion queue. Its AltiVec unit provides full 128-bit vector processing with dedicated VRF, VSIU, VCIU, and VFPU subunits.

It features a dual-bus architecture: a 32-bit address / 64-bit data MPX bus compatible with 60x processors, and a separate 19-bit L2 address / 32- or 64-bit L2 data bus supporting configurable direct-mapped SRAM mode. Core voltage is fixed at 1.8 V ±100 mV, while I/O voltages are selectable (1.8 V, 2.5 V, or 3.3 V) via BVSEL/L2VSEL pins sampled at HRESET negation.

Key Specifications

Pinout & Package

MC7410VU500LE is housed in a surface-mount 360-ball high-coefficient-of-thermal-expansion ceramic ball grid array (HCTE_CBGA) package with 1.27 mm pitch, optimized for thermal dissipation in high-power embedded applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar RISC microprocessor applications.

Compared with MC7410VU500LE, MPC7447A offers higher clock rate and integrated L2 but eliminates external L2 flexibility and bus compatibility, while PPC440EP trades AltiVec and MPX bus support for lower power and integrated peripherals - making each suitable only for distinct architectural migration paths.

Availability

MC7410VU500LE is available at Aetrix Electronics and suitable for digital media terminals, network control planes, industrial motion controllers, and avionics data concentrators requiring stable component supply throughout extended product lifecycles.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a leading designer of embedded processors, analog, and connectivity solutions for automotive, industrial, and networking markets.

The MPC7410 product line was developed to deliver high-performance, AltiVec-accelerated PowerPC computing for demanding embedded applications where deterministic real-time behavior and thermal efficiency were critical design constraints.

FAQ

What is the maximum guaranteed operating frequency of the MC7410VU500LE?

The MC7410VU500LE is binned and tested to guarantee 500 MHz core operation under full-on mode at 105°C junction temperature and 1.8 V ±100 mV VDD. This rating assumes compliant SYSCLK input (33–133 MHz), proper PLL_CFG[0:3] configuration, and adherence to thermal resistance limits specified for the HCTE_CBGA package.

Does the MC7410VU500LE support 3.3 V I/O on the L2 bus interface?

No. The MC7410VU500LE does not support 3.3 V I/O on the L2 bus interface. L2VSEL selects only 1.8 V or 2.5 V thresholds for L2OVDD; 3.3 V operation is explicitly disabled on the L2 bus per the hardware specifications document. Only the processor bus (OVDD) supports 3.3 V in Rev. 1.4 and later versions.

How is the L2 cache size configured for the MC7410VU500LE?

The MC7410VU500LE does not contain integrated L2 cache. It implements an external L2 cache interface supporting 512 KB, 1 MB, or 2 MB two-way set-associative configurations using synchronous BurstRAMs, or direct-mapped SRAM modes of 256 KB–2 MB. Configuration is controlled via L2CR register writes and physical SRAM population on the board.

What power management modes are available on the MC7410VU500LE?

The MC7410VU500LE provides three static low-power modes: doze (core clocks stopped, bus active), nap (core and bus clocks stopped, memory retained), and sleep (all clocks stopped, PLL/DLL disabled). In sleep mode with PLL/DLL disabled, typical power drops to 600 mW at 500 MHz - enabling rapid wake-up while minimizing standby consumption.

Is the MC7410VU500LE pin-compatible with earlier MPC7400-series processors?

No. While the MC7410VU500LE maintains MPX bus mode compatibility with 60x processors, it is not pin-compatible with MPC7400-series devices due to added AltiVec-related signals, revised L2 interface pin assignments (including L2ASPARE repurposed as L2A18), and removal of 3.3 V L2 I/O support. Board-level redesign is required for migration.
