PCX7457VGU933NC

The PCX7457VGU933NC is a PowerPC G4 microprocessor IC featuring a single 32-bit core running at 933 MHz in a 360-HiTCE-CBGA (25×25) surface-mount package. It is designed for embedded and industrial computing applications that require a combination of processing performance, integrated cache hierarchy, and industrial temperature operation.

Key value propositions include a high-performance superscalar core architecture with integrated L1 and L2 caches, a dedicated L3 interface for high-bandwidth backside cache or private SRAM, and power-saving modes suitable for embedded systems.

Key Features

• Core & Architecture PowerPC G4 core, single 32-bit processor operating at 933 MHz; superscalar design with multiple execution units as described in the PC7457 family documentation.
• Memory Subsystem Integrated L1 cache (36 KB instruction + 32 KB data) and 512 KB integrated L2. Backside L3 interface supports external SRAM (up to 4 MB of SRAM with up to 2 MB usable as cache and remaining as private memory as documented for the series).
• Bus & Addressing 64-bit data and 36-bit address bus interface with a 4 GB direct addressing range and virtual memory capability described as 4 hexabytes (2^52) in the series documentation.
• Configurable Interfaces Selectable bus clock divisors, selectable core-to-L3 frequency divisors, and selectable MPx/60x and L3 interface voltages (1.8 V or 2.5 V) as provided in the PC7457 family specification.
• Power Management Built-in power-saving modes including Nap, Doze, and Sleep to reduce power consumption in embedded applications.
• Package & Mounting 360-HiTCE-CBGA (25×25) ceramic BGA package, surface-mount mounting type; package case listed as 360-BCBGA.
• Operating Range & Compliance Industrial-grade device with operating temperature range of -40 °C to 110 °C and RoHS compliance.
• Graphics No graphics acceleration—processor is focused on general-purpose and compute-oriented embedded workloads.

Typical Applications

• Networking Equipment High-performance packet processing and control-plane functions leveraging the PowerPC G4 core and integrated cache hierarchy.
• Embedded Computing Industrial controllers and embedded servers that require deterministic performance and industrial temperature operation.
• Communications Systems Baseband control and protocol processing where a superscalar core and configurable bus interfaces are advantageous.
• Industrial Automation Real-time control, data aggregation, and system management functions benefiting from integrated caches and power-saving modes.

Unique Advantages

• Integrated Cache Hierarchy: On-chip L1 and 512 KB L2 reduce external memory bandwidth demands and simplify system memory design.
• Backside L3 Support: Dedicated high-bandwidth L3 interface enables use of external SRAM for expanded cache or private memory, improving throughput for memory-intensive tasks.
• Industrial Temperature Rating: Rated for -40 °C to 110 °C, making the device suitable for harsh embedded environments.
• Configurable Interface Voltages: Selectable interface voltages (1.8 V or 2.5 V) provide flexibility for integration with a range of system I/O voltages.
• Power-Saving Modes: Nap, Doze, and Sleep modes allow designers to optimize power consumption in battery-backed or power-sensitive systems.
• RoHS Compliant: Meets RoHS requirements for restricted substances in manufacturing.
