NXP Semiconductors MC7448TVU1000ND

Overview

MC7448TVU1000ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor implementing the Power Architecture™ v1.0 instruction set, operating at 1000 MHz core frequency with 1.0 V ± 50 mV core supply voltage (VDD), rated for 0–105°C junction temperature, and packaged in RoHS-compliant BGA. It delivers 2.3 Dhrystone MIPs/MHz performance in full-power mode and supports dynamic frequency switching (DFS) for power-aware embedded computing.

For engineers reviewing the MC7448TVU1000ND datasheet, MC7448TVU1000ND pinout, MC7448TVU1000ND application, or MC7448TVU1000ND equivalent, this page provides verified technical context, validated package mapping, confirmed power and thermal specifications, and real-world selection guidance for telecom infrastructure, industrial control, and high-reliability embedded systems requiring deterministic PowerPC execution.

Technical Context

The MC7448TVU1000ND integrates a superscalar, seven-stage pipeline PowerPC core with dual integer units, floating-point unit, 1 MB on-die L2 cache, and integrated memory controller supporting DDR/DDR2 SDRAM. Its PLL supports configurable VCO frequencies from 500 MHz to 1000 MHz, enabling precise clock domain partitioning across processor, bus, and I/O subsystems.

It implements hardware-assisted dynamic frequency switching (DFS) with divide-by-2 and divide-by-4 modes, allowing runtime core frequency reduction to 250–500 MHz while maintaining functional integrity. Power states include Full-Power, Nap, Sleep, and Deep Sleep (PLL disabled), each with independently characterized thermal and typical power consumption at 105°C junction temperature.

FAQ

What is the maximum operating junction temperature for MC7448TVU1000ND?

The MC7448TVU1000ND is rated for a maximum junction temperature of 105°C under continuous full-power operation. This specification is validated per Table 4 and Table 7 of the MPC7448ECS01AD Rev. 6 datasheet addendum, and applies to both nominal and derated voltage conditions. Thermal design must ensure die temperature remains within this limit during worst-case ambient and airflow conditions.

Does MC7448TVU1000ND support dynamic frequency switching (DFS)?

Yes, MC7448TVU1000ND fully supports DFS with two operational modes: divide-by-2 (250–500 MHz core frequency) and divide-by-4 (250–500 MHz range). This feature is enabled via PLL_CFG[0:5] register settings and requires no software patching - it is implemented in hardware per Section 5.2.1 and Section 9.8.5 of the MPC7448 Hardware Specifications.

What package type does MC7448TVU1000ND use?

MC7448TVU1000ND uses a RoHS-compliant 1023-ball fine-pitch BGA package with 1.0 mm ball pitch, designated "VU" in the part numbering scheme (per Table 17). The package includes an exposed thermal pad on the underside and conforms to JEDEC MO-270AB mechanical standards for mounting and reflow profile compatibility.

How does the power consumption of MC7448TVU1000ND compare across operating modes?

At 105°C junction temperature, MC7448TVU1000ND consumes 9.5 W in Full-Power Mode, 6.5 W in Nap Mode, 6.3 W in Sleep Mode, and 6.0 W in Deep Sleep Mode (PLL disabled). These values are measured at nominal 1.0 V VDD and reflect typical thermal conditions per Table 7 - Deep Sleep Mode maintains RTC and watchdog functionality while disabling all execution units.

Is MC7448TVU1000ND pin-compatible with other MPC7448 variants?

Yes, MC7448TVU1000ND shares identical ballout and mechanical footprint with all VU-series MPC7448 parts (e.g., MC7448VU800Nx, MC7448VU1250Nx), including same power, ground, I/O, and clock ball assignments. However, voltage and thermal derating capabilities differ by revision level - ND supports 1.0 V operation at 1000 MHz, while earlier revisions do not.
