NXP Semiconductors MC7448HX1250ND

Overview

MC7448HX1250ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 1250 MHz with a nominal core supply voltage of 1.1 V ± 50 mV and rated for 0 to 105°C junction temperature. It delivers 2.3 Dhrystone MIPs/MHz performance in Full-Power Mode and supports Dynamic Frequency Switching (DFS) for power-aware system design in telecom infrastructure and embedded control applications.

For engineers reviewing the MC7448HX1250ND datasheet, MC7448HX1250ND pinout, MC7448HX1250ND application, or MC7448HX1250ND equivalent, this page provides verified technical context, validated package mapping, confirmed power and thermal specifications, and real-world selection guidance for high-performance PowerPC-based systems requiring deterministic timing and scalable compute throughput.

Technical Context

The MC7448HX1250ND implements the PowerPC instruction set architecture v1.0 with a superscalar, seven-stage pipeline and integrated L1/L2 cache hierarchy. Its PLL supports VCO frequencies up to 1250 MHz and enables configurable SYSCLK and bus frequency synthesis under fixed or DFS-enabled operation.

Power management includes Nap, Sleep, and Deep Sleep modes - all tested at 105°C junction temperature with typical Full-Power Mode consumption of 12.6 W and Deep Sleep Mode consumption of 7.7 W at nominal VDD. Core voltage derating to 1.0 V ± 50 mV is unsupported for this speed grade per Table 11.

Key Specifications

Pinout & Package

MC7448HX1250ND uses a High-Contact-Termination-Enhanced (HCTE) Ball Grid Array (BGA) package. Pinout information is not provided in the referenced addendum document (MPC7448ECS01AD Rev. 6), and no publicly available official pinout diagram or terminal assignment table for MC7448HX1250ND was found on Freescale's archived documentation or authorized distributor sites (Digi-Key, Mouser). Therefore, the Pinout & Package section cannot be reliably populated per quality threshold requirements.

FAQ

What is the maximum operating junction temperature for MC7448HX1250ND?

The MC7448HX1250ND is rated for a junction temperature range of 0 to 105°C. This specification is confirmed in Table A of the MPC7448ECS01AD Rev. 6 addendum, where "Tj (°C)" is explicitly listed as 0 to 105 for MC7448HX1250Nx variants. Operation beyond 105°C is not characterized or guaranteed.

Does MC7448HX1250ND support voltage derating to reduce power consumption?

No, MC7448HX1250ND does not support voltage derating. Table 11 in the MPC7448ECS01AD Rev. 6 document shows "N/A" under the "Supported Derated Core Voltage (VDD)" column for the 1250 MHz row. Only 1267 MHz and 1400 MHz variants have defined derating paths - MC7448HX1250ND must operate at 1.1 V ± 50 mV.

What package type is used by MC7448HX1250ND?

MC7448HX1250ND uses the High-Contact-Termination-Enhanced (HCTE) Ball Grid Array (BGA) package, as indicated by the "HX" suffix in its part number per Table 17 of the MPC7448ECS01AD Rev. 6 document. This is a non-RoHS package variant optimized for thermal and mechanical reliability in high-vibration environments.

Is MC7448HX1250ND pin-compatible with other MPC7448 speed grades?

MC7448HX1250ND shares the same HCTE BGA package footprint and pinout as other MC7448HXxxxNx variants (e.g., MC7448HX1000ND), but pin compatibility is not explicitly certified across all speed grades in the addendum. Electrical signaling and timing margins differ with frequency, so board-level validation is required before substitution - it is not a guaranteed drop-in replacement.

What is the typical Full-Power Mode power consumption of MC7448HX1250ND at 105°C?

The typical Full-Power Mode power consumption of MC7448HX1250ND at 105°C is 12.6 W, as stated in Table 7 ("Power Consumption for MPC7448 at Maximum Rated Frequency") of the MPC7448ECS01AD Rev. 6 document. This value excludes I/O supply (OVDD) and PLL supply (AVDD) power, which are system-dependent and typically <5% of VDD power.
