Product details
Overview
MC7448HX1267ND 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 junction temperature range of 0–105°C. It implements the PowerPC instruction set architecture version 1.0 and targets high-performance embedded computing applications such as network infrastructure control planes and telecom baseband processing.
For engineers reviewing the MC7448HX1267ND datasheet, MC7448HX1267ND pinout, MC7448HX1267ND application, or MC7448HX1267ND equivalent, this page delivers verified specifications, thermal/power behavior at nominal and derated conditions, package mapping to HCTE BGA, and validated alternative options for migration or sourcing continuity.
Technical Context
The MC7448HX1267ND uses a superscalar, seven-stage pipeline with dual integer units, floating-point unit, and 1 MB on-die L2 cache. Its PLL supports VCO frequencies up to 1267 MHz and enables dynamic frequency switching (DFS) with 250–633 MHz operational range when enabled.
Power management includes Full-Power, Nap, Sleep, and Deep Sleep modes - with typical full-power consumption of 8.4 W at 105°C and 65°C nominal thermal conditions. Voltage and frequency derating is supported: at 1.0 V ± 50 mV, maximum core frequency reduces to 1000 MHz with full-power mode consumption dropping to 6.0 W (typical, thermal).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Frequency | 1267 MHz maximum rated; supports DFS down to 250 MHz - enables runtime power/performance scaling in real-time systems. |
| Core Supply Voltage (VDD) | 1.05 V ± 50 mV - revision-level D-specific voltage optimized for lower power vs. 1.1 V revision C parts at same frequency. |
| Junction Temperature Range | 0°C to 105°C - qualified for industrial-temperature operation without external cooling augmentation in controlled airflow environments. |
| Full-Power Mode Power (Typical, Thermal) | 10.3 W at 105°C - measured under Dhrystone 2.1 load; informs heatsink sizing and system-level thermal budgeting. |
| L2 Cache Size | 1 MB unified - reduces memory latency for deterministic real-time execution in packet processing and control-plane firmware. |
| Instruction Set | PowerPC ISA v1.0 - ensures binary compatibility with legacy PowerPC toolchains and OS support (e.g., VxWorks, LinuxPPC). |
| Dynamic Frequency Switching | Supported with divide-by-2 and divide-by-4 modes - allows software-controlled clock throttling during low-load periods to reduce average power. |
Pinout & Package
MC7448HX1267ND is packaged in a 515-ball HCTE (High Conductivity Thermal Enhanced) BGA with 1.0 mm ball pitch and 27 × 27 mm body size. The package features integrated thermal lid and enhanced thermal dissipation via solder balls arranged in thermal array zones.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Balls A1–A10, B1–B10, etc.) | Core power supply input | Distributed across 48 dedicated balls; requires local 1.05 V ± 50 mV regulation with ≤10 mV ripple for stable 1267 MHz operation. |
| OVDD (Balls E1–E10, F1–F10, etc.) | I/O power supply input | Supplies 2.5 V or 3.3 V to processor I/O banks; decoupling must isolate OVDD from VDD to prevent noise coupling into core logic. |
| AVDD (Balls M1–M5, N1–N5) | PLL analog supply input | Filtered 1.05 V ± 50 mV supply feeding PLL circuitry; requires separate LC filter per Freescale Section 9.2.2 to suppress jitter. |
| RESET_IN# | Asynchronous active-low reset input | Asserted to initialize processor state; must be held low ≥100 ns after VDD reaches regulation; synchronous deassertion required for boot sequence integrity. |
| CLKIN | Differential clock input | Accepts 33–100 MHz differential SYSCLK; used by internal PLL to generate 1267 MHz core clock - timing margin critical for lock stability. |
| PLLVDD/PLLVSS | PLL power/ground terminals | Dedicated power rails isolated from digital VDD; mandatory separation prevents phase noise degradation in high-frequency PLL operation. |
Key Features
| Feature | Design Value |
|---|---|
| Thermal-optimized revision D core voltage | 1.05 V ± 50 mV enables 1267 MHz operation with 1.7 W lower typical thermal power vs. 1.1 V revision C variant - reduces heatsink mass and fan requirements. |
| On-die 1 MB L2 cache | Reduces off-chip memory accesses by >60% in control-plane packet inspection workloads - improves determinism and lowers DDR bandwidth pressure. |
| Dynamic Frequency Switching (DFS) | Hardware-supported 2× and 4× clock division allows runtime frequency reduction to 633 MHz or 316 MHz - cuts dynamic power by ~75% in idle or low-throughput states. |
| HCTE BGA thermal performance | Thermal resistance θJA = 12.5°C/W (JEDEC Std-51-2); enables passive cooling in 5 W–10 W system envelopes without forced airflow. |
| Industrial temperature qualification | Validated across 0–105°C junction range - eliminates need for extended-temperature grade components in outdoor telecom cabinets or factory automation controllers. |

FAQ
What is the core supply voltage specification for MC7448HX1267ND?
The MC7448HX1267ND requires a core supply voltage of 1.05 V ± 50 mV, which is specific to revision level D devices. This voltage is lower than the 1.1 V used by revision C variants at the same 1267 MHz frequency, enabling reduced dynamic power consumption without sacrificing peak performance. The MC7448HX1267ND datasheet specifies tight regulation tolerance to maintain timing margins at maximum frequency.
Does MC7448HX1267ND support dynamic frequency switching (DFS)?
Yes, MC7448HX1267ND supports DFS with two modes: divide-by-2 (633 MHz) and divide-by-4 (316 MHz). When enabled, DFS allows software to scale core frequency in real time to match workload demands, reducing average power consumption by up to 75% in low-activity states. The MC7448HX1267ND hardware implements this feature via dedicated PLL configuration registers and does not require external clock sources.
What package type is used for MC7448HX1267ND?
MC7448HX1267ND uses a 515-ball HCTE (High Conductivity Thermal Enhanced) BGA package with 1.0 mm ball pitch and 27 × 27 mm body size. This package integrates a copper thermal lid and optimized solder ball placement for enhanced heat transfer, achieving θJA = 12.5°C/W under JEDEC standards - making it suitable for convection-cooled industrial applications without active fans.
How does MC7448HX1267ND differ from MC7448HX1267NC?
The MC7448HX1267ND operates at 1.05 V ± 50 mV, whereas MC7448HX1267NC requires 1.1 V ± 50 mV. Both run at 1267 MHz and share identical instruction set, cache, and peripheral interfaces, but the ND revision achieves lower thermal power (10.3 W typical at 105°C vs. 12.0 W for NC), enabling more compact thermal solutions. The MC7448HX1267ND also incorporates updated PVR value 0x8004_0202 per Freescale documentation.
Is MC7448HX1267ND qualified for industrial temperature operation?
Yes, MC7448HX1267ND is fully qualified for operation across a junction temperature range of 0°C to 105°C. This qualification covers all specified electrical parameters including core frequency, power consumption, and I/O timing - verified under thermal stress testing per Freescale's industrial reliability standards. The MC7448HX1267ND is commonly deployed in uncooled telecom cabinets and factory-floor controllers where ambient temperatures exceed 70°C.
