NXP Semiconductors MC7447AVU1000NB

Overview

MC7447AVU1000NB from Freescale Semiconductor is a PowerPC™ RISC microprocessor with 1000 MHz core frequency, 1.1 V ±50 mV core supply, and RoHS-compliant BGA package. It delivers 2.3 Dhrystone MIPs/MHz at 65°C and supports full-power, nap, sleep, and deep-sleep modes for embedded computing in telecom infrastructure and industrial control systems.

For engineers reviewing the MC7447AVU1000NB datasheet, MC7447AVU1000NB pinout, MC7447AVU1000NB application, or MC7447AVU1000NB equivalent, key selection criteria include verified 1000 MHz operation at 1.1 V nominal, derated 800 MHz capability at 1.0 V, thermal performance up to 105°C junction temperature, and compatibility with MPC7447A hardware specification Rev. 3 or later.

Technical Context

The MC7447AVU1000NB implements a superscalar, seven-stage pipeline PowerPC G4-compatible core with integrated L1 cache (32 KB instruction + 32 KB data) and supports dynamic frequency switching (DFS). Its PLL generates a 2000 MHz VCO output from a 500–1000 MHz input, enabling precise clock synthesis for synchronous bus interfaces.

It operates under two validated voltage/frequency regimes: nominal (1.1 V / 1000 MHz) and derated (1.0 V / 800 MHz), with full-power mode consuming up to 11.5 W and deep-sleep mode drawing only 1.2 W. Bus timing complies with MPC7447A processor bus AC specifications, requiring external SYSCLK and PLL_CFG[0:4] configuration per Section 9.1 of the base hardware spec.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating junction temperature for MC7447AVU1000NB?

The MC7447AVU1000NB has a maximum rated junction temperature of 105°C, as specified in Table 2 of the MPC7447AECS01AD Rev. 3 addendum. This value defines the upper thermal limit for sustained full-power operation and must be maintained through appropriate heatsinking and airflow design. The MC7447AVU1000NB's derated operation at 1.0 V does not extend this temperature rating.

Does MC7447AVU1000NB support dynamic frequency switching (DFS)?

Yes, the MC7447AVU1000NB supports dynamic frequency switching as documented in the MPC7447A RISC Microprocessor Hardware Specifications. DFS allows runtime adjustment of core frequency between 500 MHz and 1000 MHz without reset, enabling adaptive power management. The MC7447AVU1000NB requires proper SYSCLK and PLL_CFG[0:4] configuration to maintain valid VCO and bus timing during transitions.

What package type does MC7447AVU1000NB use and what are its key mechanical features?

The MC7447AVU1000NB uses a RoHS-compliant BGA package with 515 balls, 1.0 mm pitch, and a 35 mm × 35 mm body size. It is marked per Figure 1 in the MPC7447AECS01AD Rev. 3 document, including assembly traceability code YWWLAZ and test code AWLYYWW. The MC7447AVU1000NB package is optimized for lead-free reflow and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 requirements.

How does the power consumption of MC7447AVU1000NB compare between full-power and deep-sleep modes?

In full-power mode, the MC7447AVU1000NB consumes up to 11.5 W maximum and 8.0 W typical at 1000 MHz and 1.1 V. In deep-sleep mode (PLL disabled), it draws only 1.2 W typical - a 90% reduction. This difference enables aggressive power gating strategies in battery-backed or thermally limited systems. The MC7447AVU1000NB maintains this deep-sleep efficiency across its full 0–105°C operating range.

Is MC7447AVU1000NB compatible with existing MPC7447A hardware designs?

Yes, the MC7447AVU1000NB is fully compatible with designs based on the MPC7447A RISC Microprocessor Hardware Specifications Rev. 3 or later. It shares identical electrical characteristics, timing parameters, and register-level architecture. However, users must verify that their PCB layout accommodates the RoHS BGA footprint and updated thermal management requirements, as the MC7447AVU1000NB replaces legacy HX-series parts in new builds.
