Built on Power Architecture technology, the device combines a superscalar integer core, a double‑precision floating‑point unit and a SIMD multimedia unit with an on‑chip 1 Mbyte L2 cache to deliver balanced compute and media capabilities for embedded and computing designs.

Key Features

• Core Architecture PowerPC G4 single‑core, 32‑bit superscalar processor operating at 1.4 GHz and implementing the PowerPC instruction set architecture.
• Floating‑Point and Multimedia Integrated double‑precision floating‑point unit plus SIMD multimedia (AltiVec) support for accelerated media and signal processing workloads.
• Cache and Memory Subsystem On‑chip 1 Mbyte L2 cache with 32‑Kbyte instruction and 32‑Kbyte data caches to reduce memory latency and improve sustained performance.
• Bus Protocol Support Memory storage subsystem supports the MPX bus protocol and a subset of the 60x bus protocol for main memory and system resource interfacing.
• System and Debug Includes features such as Time Base Counter/Decrementer, clock multiplier, JTAG/COP interface, performance monitor and thermal/power management facilities for system integration and validation.
• Instruction Handling Out‑of‑order issue capability for AltiVec instructions and hardware structures such as reservation stations and branch prediction to improve instruction throughput.
• Package and Mounting 360‑FCCBGA (25×25) supplier device package, supplied in tray format and intended for surface‑mount assembly.
• Operating Range Rated for a 0 °C to 105 °C operating temperature range.
• Graphics Acceleration No dedicated graphics acceleration — compute and multimedia are handled by the processor core, FPU and SIMD unit.

Typical Applications

• Networking Equipment Suitable for routing, switching and other network processing tasks where single‑core compute and media handling are required.
• Embedded Computing Systems Fits embedded compute platforms that require a balanced integer/FPU/simd profile and on‑chip L2 cache.
• Multimedia/Signal Processing SIMD (AltiVec) and double‑precision FPU capabilities support media‑centric processing in consumer systems.
• Consumer Electronics Consumer‑grade qualification makes the device applicable for consumer product designs requiring PowerPC G4 performance and integration.
