NXP Semiconductors MC7448HX600ND

Overview

MC7448HX600ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 600 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 features dynamic frequency switching (DFS), multiple low-power modes (Nap, Sleep, Deep Sleep), and integrated PLL with configurable VCO frequency.

For engineers reviewing the MC7448HX600ND datasheet, MC7448HX600ND pinout, MC7448HX600ND application, or MC7448HX600ND equivalent, this page delivers verified technical context, exact operating conditions, power consumption profiles across thermal conditions, derating behavior, and validated alternative options for embedded computing systems requiring deterministic real-time performance and thermal resilience.

Technical Context

The MC7448HX600ND implements a superscalar, seven-stage pipeline PowerPC core with 1 MB on-die L2 cache, supporting 64-bit addressing and dual-issue integer/FP execution. Its PLL supports programmable multiplication ratios to generate core clock from system bus clock, with VCO frequency matching core frequency (500–600 MHz) under nominal 1.0 V operation.

It supports three low-power states-Nap (6.5 W typical @105°C), Sleep (6.3 W), and Deep Sleep with PLL disabled (6.0 W)-all measured at nominal VDD and maximum junction temperature. Dynamic Frequency Switching enables runtime core frequency reduction to 250–300 MHz when enabled, reducing active power without software intervention.

Key Specifications

Pinout & Package

MC7448HX600ND uses a 515-ball HCTE BGA package (19 mm × 19 mm, 1.0 mm pitch), with ball map defined in MPC7448 Hardware Specifications Rev. 3+. Pin functions are organized into core power (VDD/VSS), I/O supply (OVDD), PLL supply (AVDD), differential clocks (SYSCLK_P/N), JTAG debug (TCK/TMS/TDI/TDO), and high-speed address/data buses (AD[0:63], BE[0:7]#, etc.). Thermal pad is center-mounted and must be soldered to PCB ground plane for thermal compliance.

FAQ

What is the maximum junction temperature specification for MC7448HX600ND?

The MC7448HX600ND is rated for a maximum junction temperature (Tj) of 105°C under continuous full-power operation. This rating is validated across all operating modes-including Full-Power, Nap, Sleep, and Deep Sleep-and defines the upper thermal limit for reliable long-term operation in industrial and avionics environments. Derating curves for voltage and frequency are provided in Table 11 of the MPC7448ECS01AD Rev. 6 specification.

Does MC7448HX600ND support dynamic frequency switching (DFS)?

Yes, MC7448HX600ND supports Dynamic Frequency Switching (DFS) with a core frequency range of 250–300 MHz when enabled. This feature allows runtime reduction of clock frequency without reset or context loss, lowering dynamic power consumption by approximately 40% during low-load intervals while preserving full architectural state and interrupt latency guarantees.

What package type does MC7448HX600ND use?

MC7448HX600ND uses a 515-ball HCTE (High-Conductivity Thermally Enhanced) BGA package measuring 19 mm × 19 mm with 1.0 mm ball pitch. The package includes an exposed thermal pad on the underside that must be soldered to a dedicated PCB ground plane for effective heat dissipation and thermal compliance.

What is the core supply voltage requirement for MC7448HX600ND?

The MC7448HX600ND requires a nominal core supply voltage (VDD) of 1.0 V ± 50 mV across its full operating temperature range (0–105°C). This fixed-voltage specification simplifies power delivery design and eliminates the need for adaptive voltage regulation, unlike higher-frequency variants (e.g., 1267 MHz or 1400 MHz) which require 1.05 V or 1.15 V rails.

Is MC7448HX600ND pin-compatible with other MPC7448 speed grades?

Yes, MC7448HX600ND shares identical pinout and package (515-ball HCTE BGA) with all other MPC7448 HX-series variants (e.g., MC7448HX667ND, MC7448HX800ND), enabling direct PCB reuse across speed grades. However, voltage and thermal management must be revalidated per speed grade due to differing power consumption and derating requirements.
