PNX1302EH,557

Overview

The PNX1302EH,557 is a media processor from the Philips Nexperia PNX1300 Series. It features an ultra-high performance Very Long Instruction Word (VLIW) processor optimized for audio, video, and graphics processing. The device includes powerful SIMD multimedia operators for 8- and 16-bit signal datatypes and full IEEE-compatible 32-bit floating-point operations. It integrates intelligent video and audio input/output subsystems, supporting real-time processing of multimedia datastreams. The architecture allows standalone operation or use as an accelerator to general-purpose processors.

Feature Summary

• Ultra-high performance VLIW DSPCPU with up to 7.7 billion operations per second
• On-chip independent DMA-driven multimedia I/O and coprocessing units
• Comprehensive instruction set including traditional microprocessor, SIMD, and IEEE floating-point operations
• PCI/XIO host bus interface supporting glueless connection to PCI and microcomputer peripherals

Applications

• Video-centric multimedia applications
• Real-time processing of video, audio, graphics, and communications datastreams
• Standalone programmable video, audio, and graphics processing
• Media acceleration for general-purpose processors

Procurement Notes

Verify the specific ordering suffix '557' against official NXP documentation to confirm package type and container details. Ensure compatibility with required SDRAM memory configurations and clock speeds specified in the PNX1300 Series datasheet. Confirm that the preliminary specification status does not impact final production requirements.

Selection Notes

Select this component for designs requiring high-performance parallel processing of multimedia streams. Consider the optional lower-voltage CPU variant if power efficiency is critical. Ensure the system design supports the required SDRAM interfaces (16-, 64-, 128-, and 256-Mbit) and utilizes the provided C/C++ software development tools for application coding.

Part Context

The PNX1302EH belongs to the TriMedia PNX1300 Series, which serves as an enhanced version of the TM-1300 family. This series maintains pin compatibility with predecessors while offering faster clock speeds and improved main memory interfaces. The technology originated from Philips Research Labs and represents a mature architecture for universal media acceleration.

Replacement Considerations

The PNX1300 Series maintains 100% pin compatibility with its TM-1300 predecessors. Designers can consider TM-1300 variants as direct replacements if performance requirements align with the older generation's capabilities.
