Product details
Overview
ASC8851AETE from NXP Semiconductors is a high-performance IP camera SoC integrating ARM926EJ-S CPU (600 MHz), dual-channel DDR-II/III controller (2 × 16-bit, up to 2 GB total), and parallel H.264 High Profile + MJPEG hardware encoders. It supports 12 MPixel raw sensor input, 1080p@45 fps H.264 main stream + 1080p@45 fps MJPEG substream, and 24-bit RGB video output at 1080p@60 fps - deployed in HD surveillance cameras requiring low-bitrate, multi-stream encoding with motion detection and encryption.
For engineers reviewing the ASC8851AETE datasheet, ASC8851AETE pinout, ASC8851AETE application, or ASC8851AETE equivalent, key selection criteria include its 600 MHz ARM926EJ-S core, dual DDR-III channels, BT.1120/BT.656 video I/O support, five I2S interfaces, and AES/SHA-256 data encryption for secure video streaming in OEM camera designs.
Technical Context
This SoC implements a full imaging pipeline: raw Bayer/CMYG 16-bit sensor interface (up to 180 MHz pixel clock), 3D noise reduction, motion-adaptive de-interlacing, digital WDR, and photometric lens correction. Its dual independent compression engines enable simultaneous H.264 High Profile (CAVLC/CABAC) and MJPEG encoding with ROI and SVC-T support.
The integrated 10/100/1000 Ethernet MAC (MII/GMII/RGMII), USB 2.0 OTG, PCIe 1.1, and four full UARTs provide robust connectivity for PTZ control, SD card storage, NAND flash boot, and remote firmware updates - all coordinated by Linux 2.6 running on the cache-enabled ARM926EJ-S core.

The ASC8851AETE supports 16-bit raw CMOS/CCD sensor input (Bayer/CMYG) up to 12 MPixel and 180 MHz pixel clock, plus standardized video interfaces including BT.656 (8-channel), BT.1120 (1-channel), and BT.601. These allow direct connection to image sensors or external decoders in ASC8851AETE-based camera designs without intermediate logic.
Does the ASC8851AETE include hardware encryption for secure video streaming?
Yes, the ASC8851AETE integrates dedicated cryptographic accelerators supporting AES, TDES, DES, and SHA-1/224/256/384/512. This enables end-to-end encrypted video transport compliant with ONVIF Profile S and enterprise security policies - a core capability built into the ASC8851AETE silicon, not dependent on software-only implementations.
What is the maximum H.264 encoding performance of the ASC8851AETE?
The ASC8851AETE achieves up to 1080p@45 fps H.264 High Profile encoding with CAVLC/CABAC entropy coding, two reference frames, ROI, and SVC-T. This is confirmed in NXP's ASC885xA selection guide and exceeds ASC8850AETE (35 fps) while falling short of ASC8852AETE (65 fps), positioning ASC8851AETE for mainstream HD camera applications.
How many DDR memory channels does the ASC8851AETE support, and what is the maximum capacity?
The ASC8851AETE supports two independent 16-bit DDR-II/III memory channels, each operating up to 400 MHz. Each channel supports up to 1 GB DDR-III or 512 MB DDR-II, enabling a total system memory capacity of up to 2 GB - sufficient for concurrent ISP, encoding, OS, and network stack operations in ASC8851AETE-based platforms.
Is the ASC8851AETE pin-to-pin compatible with other members of the ASC885xA family?
Yes, the ASC8851AETE is fully pin-to-pin and software-compatible with ASC8850AETE and ASC8852AETE in the TFBGA-484 package. This allows hardware reuse across performance tiers - for example, upgrading from ASC8850AETE to ASC8851AETE requires only firmware update and no PCB redesign, as confirmed in NXP's migration documentation.
