NXP Semiconductors MC7448VU1000ND

Overview

MC7448VU1000ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 1000 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 low-power modes, and integrated PLL clock generation. It targets high-performance embedded computing in telecom infrastructure and network processing systems.

For engineers reviewing the MC7448VU1000ND datasheet, MC7448VU1000ND pinout, MC7448VU1000ND application, or MC7448VU1000ND equivalent, key selection criteria include verified 1000 MHz full-power operation at 1.0 V, thermal power consumption of 12.0 W at 105°C, RoHS-compliant BGA package compatibility, and support for voltage/frequency derating to 1000 MHz at reduced VDD.

Technical Context

The MC7448VU1000ND integrates a superscalar, seven-stage pipeline PowerPC core with dual integer units, floating-point unit, and 1 MB on-die L2 cache. Its PLL supports configurable VCO frequencies from 500–1000 MHz, and DFS enables runtime core frequency scaling between 250–500 MHz when enabled.

Power management includes hardware-controlled Nap, Sleep, and Deep Sleep modes-achieving typical Deep Sleep power of 6.0 W at 105°C-and supports voltage derating per Table 11, where 1.0 V operation is validated for 1000 MHz maximum frequency without performance penalty.

Key Specifications

FAQ

What is the maximum validated core frequency of the MC7448VU1000ND?

The MC7448VU1000ND is fully tested and characterized at 1000 MHz under nominal 1.0 V ± 50 mV core supply and 0–105°C junction temperature. This speed grade is confirmed in Table A and Table 8 of the MPC7448ECS01AD Rev. 6 specification, with no derating required for rated operation. The MC7448VU1000ND does not support operation above 1000 MHz, even with increased voltage.

Does the MC7448VU1000ND support dynamic voltage and frequency scaling (DVFS)?

The MC7448VU1000ND supports Dynamic Frequency Switching (DFS) - reducing core frequency to 250–500 MHz when enabled - but does not support dynamic voltage scaling. Core voltage remains fixed at 1.0 V ± 50 mV across all DFS states. Voltage derating to 1.0 V is permitted only for fixed-frequency operation at ≤1000 MHz, as defined in Table 11 of the MC7448ECS01AD Rev. 6 document.

What package type does the MC7448VU1000ND use, and how is it marked?

The MC7448VU1000ND uses a RoHS-compliant 1023-ball fine-pitch BGA package (1.0 mm pitch), identified by the "VU" suffix per Table 17. Marking follows the format "xx7448 xxnnnnNx", where "VU1000ND" indicates RoHS BGA, 1000 MHz speed, and revision level D (PVR = 0x8004_0202). Assembly traceability code and date code appear per Figure 23.

How does the power consumption of MC7448VU1000ND compare in Nap vs. Deep Sleep mode?

At 105°C junction temperature, the MC7448VU1000ND consumes 6.5 W in Nap mode and 6.0 W in Deep Sleep mode (PLL disabled), per Table 7 of MPC7448ECS01AD Rev. 6. Both values reflect typical thermal conditions at nominal 1.0 V supply. Deep Sleep achieves the lowest power state by gating clocks to all major subsystems except essential retention logic.

Is the MC7448VU1000ND pin-compatible with other MPC7448 speed grades like MC7448VU1250ND?

No - the MC7448VU1000ND is not pin-compatible with MC7448VU1250ND. Although both share the same 1023-ball BGA footprint, the 1250 MHz variant requires 1.1 V ± 50 mV core supply and revised power delivery network layout per Section 5.1. Mixing them on the same PCB risks undervoltage lockout or thermal runaway; each speed grade demands dedicated voltage regulation and thermal design per its validated operating conditions.
