ASC8851AETE

Overview

The ASC8851AETE is a specialized processor designed for high-definition IP camera applications, featuring an ARM926EJ-S core operating at 600 MHz. It supports up to 12 MPixel sensor input and delivers H.264 High-Profile compression performance of 1080p @ 45 fps or D1 @ 30 fps across nine parallel streams. The device integrates independent hardware engines for H.264, MPEG-4, and MJPEG encoding, alongside advanced image signal processing capabilities including 3D noise reduction and motion adaptive de-interlacing. Memory support includes two SDRAM channels accommodating up to 2 GB total capacity via DDR-II/III interfaces.

Feature Summary

• H.264 High-Profile video compression supporting 1080p @ 45 fps or multi-stream D1 output
• Integrated ARM926EJ-S CPU running at 600 MHz with 16 KB I-Cache and 16 KB D-Cache
• Advanced Image Signal Processing (ISP) pipeline with 3D noise reduction and digital WDR
• Support for up to 12 MPixel sensors with 16-bit raw data interface

Applications

• Surveillance IP cameras
• Car video recorders
• Digital video recorders (up to 8x D1)
• Video conferencing systems
• Industrial vision applications

Procurement Notes

Verify the specific ordering suffix 'ETK' against official NXP documentation to confirm package type and temperature range specifications. Confirm current manufacturing status as distribution listings indicate potential discontinuation. Ensure compatibility with existing SDKs and reference designs when integrating into new hardware architectures.

Selection Notes

Select this model for designs requiring simultaneous multi-stream encoding with independent H.264 and MJPEG hardware engines. The 600 MHz ARM926EJ-S core provides sufficient processing power for complex ISP tasks like auto white balance and exposure control. Verify that the target application requires the specific 1080p @ 45 fps H.264 performance ceiling rather than higher frame rates available in other family members.

Part Context

The ASC8851A belongs to the ASC885xA family of integrated solutions for full HD security cameras. This family offers pin-to-pin compatibility with previous generations, facilitating design upgrades without hardware modifications. The 'Advanced' version distinguishes itself through enhanced low-light image enhancement and support for frame rates up to 1080p/60 fps.

Replacement Considerations

ASC8852A: Offers higher H.264 performance (1080p @ 65 fps). ASC8850A: Lower frequency (400 MHz) and reduced sensor resolution support (5 MPixels).
