ASC8850ET/M2,557

Overview

The ASC8850ET/M2,557 is a single-chip IP camera solution from NXP USA Inc., designed for full HD video processing. It features an ARM926EJ-S CPU running at up to 600 MHz and supports up to 12 MPixels raw data input. The device integrates image signal processing, H.264/MPEG-4/MJPEG compression, and network transmission capabilities. Key electrical parameters include support for up to 1080p @ 30 fps or 6 x D1 @ 30 fps in H.264 encoding, 2x 16-bit SDRAM channels supporting up to 1 GB DDR-III each, and a 484-TFBGA package measuring 15 x 15 mm with a 0.65 mm pitch.

Feature Summary

• Integrated ARM926EJ-S CPU operating at up to 600 MHz
• Supports up to 12 MPixels raw data input with 16-bit interface
• Hardware compression engine for H.264 (up to 1080p @ 30 fps), MPEG-4, and MJPEG
• Advanced image processing including digital WDR, noise reduction, and lens distortion correction

Applications

• Security IP cameras
• Video conferencing systems
• Video door phones and intercoms
• Industrial vision solutions

Procurement Notes

Verify the M2 suffix indicates the specific hardware revision documented in the datasheet. Confirm RoHS compliance status as per the manufacturer's certification. Check for end-of-life notifications or long-term supply agreements if planning for extended production runs. Ensure the 484-TFBGA footprint matches the PCB design constraints.

Selection Notes

Select this model for applications requiring high-resolution video processing up to 12 MPixels and multi-stream encoding capabilities. Compare against the ASC884x series if lower resolution or different interface requirements are needed. Consider the integrated Ethernet MAC and USB OTG interfaces for connectivity needs without external controllers.

Part Context

The ASC8850ET belongs to the ASC884x/ASC885x family of single-chip solutions for IP cameras. This family offers pin-to-pin and software-compatible products, allowing for flexible platform deployment. The ASC8850 variant specifically targets higher performance requirements compared to the ASC8848 and ASC8849 models within the same series.

Replacement Considerations

The ASC8851 is a pin-to-pin compatible alternative within the same family, offering higher single-stream video compression performance (up to 1080p @ 45 fps). Verify software compatibility when substituting between these variants.
