NXP Semiconductors MC7447AVU600NB

Overview

MC7447AVU600NB from Freescale Semiconductor is a PowerPC™ RISC microprocessor with 600 MHz core frequency, 1.1 V ±50 mV core supply, and RoHS-compliant BGA package. It delivers 2.3 Dhrystone MIPs/MHz performance at 65°C and supports Nap, Sleep, and Deep Sleep power management modes for embedded computing systems requiring thermal and power efficiency.

For engineers reviewing the MC7447AVU600NB datasheet, MC7447AVU600NB pinout, MC7447AVU600NB application, or MC7447AVU600NB equivalent, key selection criteria include verified 600 MHz operation at 1.1 V nominal, full-power mode consumption of 6.0 W typical / 8.2 W max, RoHS BGA packaging, and compatibility with MPC7447A hardware specification Rev. 3 or later.

Technical Context

The MC7447AVU600NB implements a superscalar, seven-stage pipeline PowerPC G4+ core with integrated L1 cache (32 KB instruction + 32 KB data) and supports dynamic frequency switching (DFS). Its PLL generates a 600 MHz core clock from a lower-frequency SYSCLK input, with VCO operating at 1000–1200 MHz.

It operates across 0–105°C junction temperature range and supports voltage derating to 1.0 V ±50 mV for reduced power (533 MHz max, 4.2 W typical), while maintaining full bus interface compliance with MPC7447A processor bus AC timing specifications.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating junction temperature for MC7447AVU600NB?

The MC7447AVU600NB has a specified maximum junction temperature of 105°C under recommended operating conditions. This rating is validated for continuous operation at 600 MHz and 1.1 V core supply, and it defines the upper thermal limit for heatsink and airflow design. Exceeding this temperature may trigger thermal throttling or irreversible device degradation. The MC7447AVU600NB must be operated within this range to ensure reliability in industrial environments.

Does MC7447AVU600NB support dynamic frequency switching (DFS)?

Yes, the MC7447AVU600NB supports dynamic frequency switching (DFS) as defined in the MPC7447A RISC Microprocessor Hardware Specifications. DFS allows runtime adjustment of the core frequency between supported bins (e.g., 600 MHz down to derated levels) without system reset. This feature is implemented in hardware and controlled via PLL_CFG register writes. The MC7447AVU600NB leverages DFS to balance performance and power in adaptive embedded applications.

What package type does MC7447AVU600NB use?

The MC7447AVU600NB uses a RoHS-compliant BGA package, as indicated by the "VU" suffix in its part number per Freescale's nomenclature (Table 6). It is a 361-ball, 19×19 array package with 1.0 mm ball pitch. This package supports fine-pitch surface-mount assembly and meets lead-free soldering requirements for modern electronics manufacturing. The MC7447AVU600NB's BGA footprint differs from LGA (VS) and HCTE BGA (HX) variants.

Is MC7447AVU600NB pin-compatible with other MPC7447A variants?

No, the MC7447AVU600NB is not pin-compatible with other MPC7447A variants such as MC7447AVS600NB (LGA) or MC7447AHX600NB (HCTE BGA), despite sharing identical electrical and functional specifications. Package differences - BGA vs. LGA vs. HCTE BGA - result in distinct ball/grid layouts, solder mask patterns, and thermal pad configurations. Interchangeability requires full PCB redesign. The MC7447AVU600NB must be treated as a mechanically unique variant.

What is the typical full-power mode power consumption of MC7447AVU600NB?

The typical full-power mode power consumption of MC7447AVU600NB is 6.0 W, measured at 1.1 V ±50 mV core supply, 65°C junction temperature, and while executing the Dhrystone 2.1 benchmark. This value excludes OVDD (I/O supply) and AVDD (PLL supply) power, which contribute <5% additional load. The MC7447AVU600NB's 6.0 W typical draw informs thermal interface material selection and passive heatsink sizing in sealed enclosures.
