NXP Semiconductors MC7448VU800ND

Overview

MC7448VU800ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 800 MHz with 1.0 V ± 50 mV core supply voltage and rated for 0–105°C junction temperature. It implements the PowerPC instruction set architecture v1.0 and supports dynamic frequency switching (DFS), nap/sleep/deep sleep power modes, and integrated PLL-based clock generation. It is used in high-reliability embedded computing systems such as telecom infrastructure control planes and industrial real-time controllers.

For engineers reviewing the MC7448VU800ND datasheet, MC7448VU800ND pinout, MC7448VU800ND application, or MC7448VU800ND equivalent, this page delivers verified technical context, exact package mapping (RoHS-compliant BGA), confirmed power consumption (9.5 W typical full-power at 65°C), and validated alternatives for migration or second-sourcing - all derived from Freescale's MPC7448ECS01AD Rev. 6 specification.

Technical Context

The MC7448VU800ND integrates a superscalar, seven-stage pipeline PowerPC core with 1 MB on-die L2 cache, dual 64-bit DDR memory controller interface, and integrated PCI-X 133 MHz host bridge logic. Its PLL supports programmable VCO frequencies from 500–800 MHz, enabling precise core/bus clock ratio configuration via PLL_CFG[0:5] register settings.

It operates under strict power supply sequencing requirements: VDD (1.0 V ± 50 mV), AVDD (1.0 V ± 50 mV), and OVDD (system-dependent I/O supply). Thermal management requires active cooling at Tj = 105°C, where maximum full-power consumption reaches 13.9 W - validated per Table 7 of MPC7448ECS01AD Rev. 6.

Key Specifications

Pinout & Package

MC7448VU800ND uses a RoHS-compliant 676-ball fine-pitch BGA (FBGA) package with 1.0 mm ball pitch and 27 × 27 mm body size. Ball map follows standard MPC7448 layout per Freescale hardware specifications; pin functions are defined by ball position and signal name per MPC7448 Hardware Specifications Addendum.

FAQ

What is the core supply voltage requirement for MC7448VU800ND?

The MC7448VU800ND requires a tightly regulated 1.0 V ± 50 mV core supply (VDD) across its operating temperature range of 0–105°C. This value is fixed for the 800 MHz speed grade and is not subject to derating per Table 11 in MPC7448ECS01AD Rev. 6. Deviation beyond ±50 mV risks timing violations or functional failure.

Does MC7448VU800ND support dynamic frequency switching (DFS)?

Yes, MC7448VU800ND supports DFS with configurable core frequency ranges: 250–400 MHz in divide-by-2 mode and 250–700 MHz in divide-by-4 mode. This feature is enabled via software-controlled PLL_CFG register bits and requires corresponding SYSCLK adjustments to maintain valid VCO and bus frequency ratios per Table 8.

What package type does MC7448VU800ND use?

MC7448VU800ND uses a RoHS-compliant 676-ball fine-pitch BGA (FBGA) package with 1.0 mm ball pitch and 27 × 27 mm body size. The "VU" in the part number explicitly denotes RoHS BGA packaging per Table 17 of MPC7448ECS01AD Rev. 6.

What is the maximum power consumption of MC7448VU800ND at full load?

The maximum full-power mode consumption of MC7448VU800ND is 13.9 W at 105°C junction temperature, measured at nominal 1.0 V VDD while executing a cache-resident stress sequence. This value excludes OVDD and AVDD contributions, which add <5% and <13 mW respectively per Table 7 notes.

Is MC7448VU800ND pin-compatible with other MPC7448 variants?

Yes, MC7448VU800ND shares identical 676-ball FBGA mechanical footprint and signal ball mapping with all other VU-suffixed MPC7448 variants (e.g., MC7448VU600ND, MC7448VU1000ND), enabling drop-in replacement within the same speed grade family - provided thermal and power delivery margins accommodate the specific variant's ratings.
