PNX9535E/V1,557

Application Specific Microcontrollers Overview

The PNX9535E is a software-enabled video and multimedia entertainment platform designed for automotive applications, qualified to AEC-Q100 Grade 3. It features a TriMedia processor with a maximum internal TM clock frequency of 243 MHz. The device supports dual video MPEG decoding and rendering on separate screens. It includes a 16-bit DDR2 SDRAM interface capable of data rates up to 533 MHz and integrates USB 2.0 High-Speed On-The-Go (OTG), PCI 2.2, and I2C-bus interfaces. The component utilizes a BGA456 package.

Application Specific Microcontrollers Feature Summary

• Automotive grade qualification according to AEC-Q100

Application Specific Microcontrollers Applications

• Front Seat Entertainment (FSE) systems
• Rear Seat Entertainment (RSE) systems
• DVD or CD playback devices with software navigation
• USB, SD card, or HDD audio/video playback devices
• In-car video source and broadcast source decoding

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and availability. Ensure compatibility with external DDR2 memory configurations, noting that while DDR1 operation is possible, it is not guaranteed. Confirm automotive grade requirements align with AEC-Q100 standards before integration into vehicle systems.

Application Specific Microcontrollers Selection Notes

Select the PNX9535E when a 16-bit DDR2 interface width is required, distinguishing it from the 32-bit variants in the family. Consider the 243 MHz maximum internal TM clock frequency for performance needs. Verify GPIO multiplexing constraints, as certain interface combinations may be mutually exclusive depending on the specific application design.

Application Specific Microcontrollers Part Context

This component belongs to the PNX953x series, which shares a fixed basic hardware platform. Key differentiators within the series include the PNX9530 and PNX9531, which offer higher clock frequencies (351 MHz and 450 MHz respectively) and a 32-bit DDR2 interface width. The PNX9535 specifically provides one video input channel compared to three in the other models.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should evaluate the PNX9530E or PNX9531E if higher processing speeds or a wider memory interface are acceptable, though pinout and feature sets differ.
