NXP Semiconductors MC7448TVU1267ND

Overview

MC7448TVU1267ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 1267 MHz with a core supply voltage of 1.05 V ± 50 mV 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 clock generation for embedded computing applications including network infrastructure and industrial control systems.

For engineers reviewing the MC7448TVU1267ND datasheet, MC7448TVU1267ND pinout, MC7448TVU1267ND application, or MC7448TVU1267ND equivalent, key selection considerations include its revision-level-D-specific 1.05 V core voltage, thermal power consumption of 10.3 W at 105°C in Full-Power Mode, DFS-enabled frequency scaling down to 250 MHz, and RoHS-compliant VU-series BGA package compatibility.

Technical Context

The MC7448TVU1267ND implements a superscalar, seven-stage pipeline PowerPC core with dual integer units, floating-point unit, and 1 MB on-die L2 cache. Its PLL supports VCO frequencies matching core frequency (500–1267 MHz) and enables synchronous bus operation via SYSCLK derivation.

Power management includes hardware-controlled Nap, Sleep, and Deep Sleep modes - with Deep Sleep disabling the PLL and reducing full-power-mode consumption by ~40% - and Dynamic Frequency Switching that allows runtime core frequency reduction to 250 MHz under software control while maintaining system responsiveness.

FAQ

What is the core supply voltage specification for MC7448TVU1267ND?

The MC7448TVU1267ND requires a core supply voltage of 1.05 V ± 50 mV, which is specific to revision-level-D devices and distinct from the 1.1 V used by revision-level-C variants like MC7448VU1267NC. This lower voltage reduces dynamic power consumption while maintaining full 1267 MHz operation at junction temperatures up to 105°C. The specification is defined in Table 4 and Section 5.1 of the MPC7448ECS01AD Rev. 6 addendum.

Does MC7448TVU1267ND support dynamic frequency scaling?

Yes, MC7448TVU1267ND supports Dynamic Frequency Switching (DFS), allowing the core frequency to be reduced to 250 MHz while the device remains operational - enabling adaptive thermal management and power savings during low-load periods. DFS operation is detailed in Section 9.8.5 of the base MPC7448 Hardware Specifications and confirmed for all 1267 MHz variants in the Rev. 6 addendum.

What package type does MC7448TVU1267ND use?

MC7448TVU1267ND uses a RoHS-compliant BGA package, indicated by the "VU" suffix in the part number. While the exact ball count and mechanical dimensions are not specified in the MPC7448ECS01AD Rev. 6 addendum, the VU-series aligns with Freescale's standard high-density BGA footprint for the MPC7448 family. Full mechanical data requires referencing the official MPC7448 Hardware Specifications Rev. 3+ documentation.

How does MC7448TVU1267ND differ from MC7448VU1267NC?

The MC7448TVU1267ND and MC7448VU1267NC share identical 1267 MHz speed grading and VU-BGA packaging, but differ in revision level and voltage: MC7448TVU1267ND is revision D (1.05 V ± 50 mV), whereas MC7448VU1267NC is revision C (1.1 V ± 50 mV). This 50 mV reduction lowers power and thermal output without sacrificing frequency, making MC7448TVU1267ND preferable for thermally sensitive designs.

What is the maximum power consumption of MC7448TVU1267ND at 105°C?

At 105°C junction temperature and nominal 1.05 V supply, MC7448TVU1267ND exhibits a maximum Full-Power Mode power consumption of 12.0 W, as specified in Table 7 of the MPC7448ECS01AD Rev. 6 addendum. This value represents worst-case operation under fully loaded execution conditions and excludes I/O (OVDD) and PLL (AVDD) supply contributions.
