MC7457RX1000LC

The MC7457RX1000LC is a PowerPC G4 32-bit microprocessor packaged in a 483-FCCBGA (29×29) surface-mount package and rated at 1.0 GHz. It combines a high-performance superscalar core with on-chip cache support and multimedia/SIMD acceleration for embedded networking and computing applications.

Designed for consumer-grade embedded systems, the device integrates a processor core with 512-Kbyte L2 cache and an L3 tag/controller to support a backside L3 cache via a dedicated high-bandwidth interface, enabling designers to scale external cache and private memory as required.

Key Features

• Core  PowerPC G4 single-core, 32-bit architecture running at 1.0 GHz for general-purpose embedded processing.
• Memory and Cache  On-chip 512-Kbyte L2 cache with an internal L3 tag and controller that supports a glueless backside L3 cache via a dedicated interface and external SRAM configurations.
• Floating Point & Multimedia  Built-in double-precision floating-point unit and a SIMD multimedia unit to accelerate numeric and media-processing workloads.
• Bus and System Interfaces  Supports MPX bus protocol and a subset of the 60x bus protocol for main memory and system resource interfacing as described in the MPC74xx hardware specification.
• Package & Mounting  483-FCCBGA (29×29) package, surface mount, suitable for compact embedded board designs.
• Operating Range & Qualification  Consumer-qualified device with an operating temperature range of 0 °C to 105 °C and RoHS compliance.
• System Design Notes  Footprint compatibility with MPC7455 applications when the core power supply is 1.3 V, enabling drop-in replacement scenarios where applicable.

Typical Applications

• Networking Equipment  Use as a protocol-processing and control processor in routing, switching, or network appliance designs that require a 1 GHz PowerPC G4 core and expandable backside cache.
• Embedded Computing Systems  Suitable for compact embedded servers or compute modules that benefit from on-chip L2 cache and an L3 cache interface for higher effective memory bandwidth.
• Multimedia and Signal Processing  SIMD multimedia support and double-precision floating-point acceleration make it appropriate for media-handling and DSP-adjacent tasks within consumer embedded products.
• Industrial/Appliance Controllers  Consumer-qualified embedded controllers that require a robust 1.0 GHz processor in a high-density BGA package and standard operating-temperature support.

Unique Advantages

• Highly integrated cache architecture: Combines 512-Kbyte L2 with an L3 tag/controller to enable external backside L3 cache, reducing external memory traffic and improving system performance.
• Balanced compute and media capabilities: The PowerPC G4 core plus double-precision FPU and SIMD multimedia unit delivers numeric and media processing without adding discrete accelerators.
• Compact, surface-mount package: 483-FCCBGA (29×29) package supports high-density board designs while providing the pinout and connectivity required for embedded systems.
• Design flexibility: Dedicated high-bandwidth L3 interface supports 1, 2, or 4 Mbytes of external SRAM configurations for scalable cache/private memory options.
• Standards-based system interfaces: Support for MPX and subset 60x bus protocols simplifies integration with legacy and contemporary system architectures described in the MPC74xx hardware specification.
• Regulatory and temperature support: RoHS compliance and a 0 °C to 105 °C operating range provide practical deployment parameters for consumer embedded products.
