NXP Semiconductors MC7448VU1400ND

Overview

MC7448VU1400ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor implementing the Power Architecture™ v1.0 instruction set, operating at 1400 MHz with 1.15 V ± 50 mV core supply (date code 0613+), rated for 0–105°C junction temperature, and packaged in RoHS-compliant BGA for high-performance embedded computing applications including telecom baseband processing and network control planes.

For engineers reviewing the MC7448VU1400ND datasheet, MC7448VU1400ND pinout, MC7448VU1400ND application, or MC7448VU1400ND equivalent, key selection criteria include verified 1400 MHz full-power operation under thermal stress (105°C), deratable voltage/frequency support down to 1000 MHz at 1.0 V, and compatibility with MPC7448 hardware specification Rev. 3+ addendum MPC7448ECS01AD Rev. 6.

Technical Context

The MC7448VU1400ND implements a superscalar, seven-stage pipeline PowerPC G4+ core with dual integer units, floating-point unit, and 1 MB on-die L2 cache. It supports Dynamic Frequency Switching (DFS) with 250–700 MHz range when enabled, and requires precise PLL configuration via PLL_CFG[0:5] to maintain valid SYSCLK, core, and VCO frequencies within ±50 mV supply tolerance.

Power delivery mandates independent sequencing of VDD (core), OVDD (I/O), and AVDD (PLL) supplies per Section 9.2; thermal design must accommodate 15.9 W maximum power at 105°C in Full-Power Mode, with Deep Sleep Mode consuming only 7.7 W under same conditions.

Key Specifications

Pinout & Package

MC7448VU1400ND uses a RoHS-compliant BGA package consistent with the MC7448VU series. Pinout information is not provided in the referenced addendum document (MPC7448ECS01AD Rev. 6) and is unavailable from publicly accessible Freescale documentation or authorized distributor resources (Digi-Key, Mouser, Arrow). Due to absence of validated pin assignment data, this section is omitted per quality threshold requirement.

FAQ

What is the core supply voltage specification for MC7448VU1400ND?

The MC7448VU1400ND requires a core supply voltage of 1.15 V ± 50 mV for operation at its rated 1400 MHz frequency, applicable to devices with date code 0613 and later. This specification supersedes earlier 1.1 V requirements for pre-0613 1400 MHz units and is validated across the full 0–105°C junction temperature range per MPC7448ECS01AD Rev. 6.

Does MC7448VU1400ND support dynamic frequency scaling?

Yes, MC7448VU1400ND supports Dynamic Frequency Switching (DFS) with core frequency ranges of 250–700 MHz when DFS is enabled, and 500–1400 MHz when disabled. DFS operation requires proper PLL_CFG[0:5] register configuration and is validated for thermal and power management in telecom and networking applications per Section 5.2.1 of the hardware addendum.

What is the maximum power consumption of MC7448VU1400ND at 105°C?

The MC7448VU1400ND has a maximum power consumption of 15.9 W in Full-Power Mode at 105°C junction temperature, as specified in Table 7 of MPC7448ECS01AD Rev. 6. This value excludes I/O supply (OVDD) and PLL supply (AVDD) power, which contribute <5% and <13 mW respectively, and defines the thermal design baseline for sustained operation.

Is MC7448VU1400ND compatible with the standard MPC7448 hardware specifications?

Yes, MC7448VU1400ND complies with the MPC7448 RISC Microprocessor Hardware Specifications Rev. 3 or later, with specifications in MPC7448ECS01AD Rev. 6 superseding prior documents only for the part numbers listed in Table A. All unaddressed parameters-including bus interface timing and memory controller behavior-remain unchanged from the base specification.

What package type does MC7448VU1400ND use?

MC7448VU1400ND uses a RoHS-compliant BGA package, designated by the "VU" prefix in its part number per Table 17 of MPC7448ECS01AD Rev. 6. This package shares mechanical and thermal characteristics with other MC7448VU-series variants, enabling footprint reuse across speed grades in system-level designs.
