MC7448HX1267NC

The MC7448HX1267NC is a single‑core PowerPC G4 microprocessor operating at 1.267 GHz in a compact 360‑FCCBGA (25×25) surface‑mount package. It is targeted for networking and computing systems applications and combines a superscalar core with on‑die memory and multimedia capabilities to address embedded compute tasks.

Built on Power Architecture technology, the device integrates a 1‑Mbyte L2 cache and supports a high‑performance memory/storage subsystem and system‑level features for thermal and power management, debug and performance monitoring.

Key Features

• PowerPC G4 Core — Single 32‑bit superscalar processor core implementing the PowerPC instruction set architecture version 1.0.
• Clock Speed — 1.267 GHz core frequency for compute‑intensive embedded workloads.
• On‑Die Memory — Integrated 1‑Mbyte L2 cache plus 32‑KB instruction and 32‑KB data L1 caches as described in the hardware specification, reducing external memory bandwidth requirements.
• Floating‑Point and SIMD — Double‑precision floating‑point unit with a SIMD multimedia unit (AltiVec) for multimedia and DSP‑style processing.
• Memory and Bus Support — Memory storage subsystem supports the MPX bus protocol and a subset of the 60x bus protocol for main memory and system resource access.
• System Features — Time base counter/decrementer, clock multiplier, JTAG/COP interface, thermal and power management, and performance monitoring facilities for system integration and debugging.
• Branch and Instruction Resources — Hardware support for out‑of‑order AltiVec issue, branch processing structures (including BTIC and BHT resources) and reservation station resources to improve instruction throughput.
• Package and Mounting — 360‑FCCBGA (25×25) supplier device package, surface mount.
• Operating Temperature — Rated for 0 °C to 105 °C operating temperature range.
• Compliance — RoHS compliant.

Typical Applications

• Networking Equipment — Suited for control‑plane and processing tasks in networking systems where PowerPC G4 architecture and on‑chip caches reduce external memory dependency.
• Embedded Computing — Appropriate for embedded computing systems requiring a single 32‑bit core with floating‑point and SIMD acceleration.
• Appliance and System Controllers — Useful in compact, surface‑mount designs that benefit from integrated L2 cache and system management features.

Unique Advantages

• Integrated L2 Cache: On‑die 1‑Mbyte L2 cache reduces external memory traffic and improves deterministic performance for embedded workloads.
• Vector and Floating‑Point Capability: Double‑precision FPU paired with a SIMD multimedia unit (AltiVec) enables efficient handling of DSP and multimedia operations on a single core.
• System Integration Features: Built‑in JTAG/COP, thermal/power management, and performance monitoring simplify development, validation, and system reliability efforts.
• Memory Bus Flexibility: Support for MPX bus protocol and a subset of the 60x bus protocol eases integration with existing memory architectures.
• Compact Surface‑Mount Package: 360‑FCCBGA (25×25) footprint supports dense board designs while offering required pinout for system interfaces.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance.
