PNX9535E/V120,557

Overview

The PNX9535E is a software-enabled video and multimedia entertainment platform from NXP, designed for automotive applications. It features a TriMedia processor running at a maximum internal TM clock frequency of 243 MHz. The device supports dual video MPEG decoding and rendering on separate screens with independent On-Screen Display control. 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, PCI 2.2, and I2C-bus interfaces. Qualified to AEC-Q100 Grade 3, it offers proprietary video post-processing algorithms for quality enhancement.

Feature Summary

• Dual video MPEG decoding and rendering with independent OSD control
• TriMedia processor operating at 243 MHz max clock frequency
• 16-bit DDR2 SDRAM interface supporting up to 533 MHz data rate
• Integrated USB 2.0 High-Speed OTG, PCI 2.2, and I2C-bus connectivity

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
• JPEG viewers for digital camera images

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and revision level. Ensure compatibility with required external memory configurations, such as the recommended MT47H16M16BG-37E DDR2 device. Confirm that the application design accounts for the 16-bit data width limitation compared to other variants in the family.

Selection Notes

Select the PNX9535E when a 16-bit DDR interface is sufficient for the system memory bandwidth requirements. This variant differs from the PNX9530 and PNX9531 by having only one video input channel and a lower processor clock speed of 243 MHz. Verify that the single video input meets the source requirements before choosing this part over the 3-input alternatives.

Part Context

This component belongs to the PNX953x family, which shares a common hardware platform but varies in processing speed and interface width. The PNX9535E specifically targets cost-sensitive automotive multimedia applications where dual video output is needed but single video input and reduced memory bandwidth are acceptable constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should evaluate the PNX9530E or PNX9531E if higher clock speeds or additional video inputs are required, noting the differences in DDR interface width and pin compatibility.
