Product details
Overview
ASC8852AETK 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 sensor input, 1080p@60 fps video output (24-bit RGB/BT.1120), and intelligent video analytics including motion detection in 16 windows - deployed in HD surveillance cameras requiring low-bitrate, low-power encoding.
For engineers reviewing the ASC8852AETK datasheet, ASC8852AETK pinout, ASC8852AETK application, or ASC8852AETK equivalent, key selection criteria include its 1080p@65 fps H.264 compression capability, dual SDRAM channel support at 400 MHz, five I2S interfaces, MII/GMII/RGMII Ethernet MAC, and pin-to-pin compatibility within the ASC885xA family for scalable camera design upgrades.
Technical Context
The ASC8852AETK implements a full imaging pipeline with dedicated ISP blocks for 3D noise reduction, motion-adaptive de-interlacing, digital WDR, and photometric/geometric lens correction. Its dual hardware encoders enable simultaneous H.264 (1080p@65 fps) and MJPEG (1080p@45 fps) streams with ROI and SVC-T support.
It integrates a 600 MHz ARM926EJ-S core with 16 KB I-cache and 16 KB D-cache running Linux 2.6, coupled with cryptographic accelerators for AES, SHA-256/384/512, and TDES - enabling secure video transmission over Ethernet (10/100/1000 MAC with RGMII) without host CPU overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IP camera SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ASC8851AETK | Same TFBGA-484 package and pinout; lower H.264 max performance (1080p@45 fps vs. 65 fps); identical ISP and crypto blocks. | Targeted at cost-sensitive 1080p@30–45 fps cameras where peak frame rate is not required. | Select ASC8851AETK when 1080p@45 fps suffices and BOM cost optimization is prioritized over maximum motion fidelity. |
| ASC8850AETK | Same package and pinout; supports only up to 1080p@35 fps H.264; single DDR channel (vs. dual); no BT.1120 output. | Suitable for mid-tier 1080p@25–35 fps cameras with simpler video output requirements (BT.656 only). | Choose ASC8850AETK for designs where DDR bandwidth demand is lower and HDMI/HD-SDI output is not needed. |
Compared with ASC8851AETK and ASC8850AETK, the ASC8852AETK delivers highest H.264 throughput (1080p@65 fps), dual DDR channels for sensor+encoder memory separation, and BT.1120 output - making it optimal for premium 12 MPixel cameras requiring forensic-level motion capture and multi-interface video routing.

FAQ
What is the maximum H.264 encoding resolution and frame rate supported by the ASC8852AETK?
The ASC8852AETK supports H.264 High Profile encoding up to 1080p@65 fps or 13× D1@30 fps (390 fps aggregate). This capability is enabled by its dedicated hardware encoder block and 600 MHz ARM926EJ-S CPU, allowing real-time compression of high-motion 12 MPixel sensor data without frame drops. The ASC8852AETK achieves this while maintaining low bitrate efficiency through ROI and SVC-T features.
Does the ASC8852AETK support both DDR-II and DDR-III memory, and what is the maximum capacity?
Yes, the ASC8852AETK supports two independent 16-bit SDRAM channels, each configurable for DDR-II (up to 512 MB) or DDR-III (up to 1 GB) at 400 MHz, for a total maximum capacity of 2 GB. This dual-channel architecture provides sufficient bandwidth for concurrent sensor input buffering, ISP processing, and H.264/MJPEG encoding - a key requirement confirmed in NXP's ASC885xA technical specs document (9397 750 17379).
How many I2S interfaces does the ASC8852AETK provide, and what audio codecs are supported?
The ASC8852AETK provides five I2S interfaces: four input-only channels and one bidirectional channel for playback. It supports G.711, AAC, AMR, and G.726 audio codecs in hardware, enabling synchronized multi-microphone capture and low-latency audio streaming alongside video. This configuration is explicitly documented in the ASC885xA technical specs and is used in ASC8852AETK-based video door phones and car recorders.
Is the ASC8852AETK pin-to-pin compatible with other members of the ASC885xA family?
Yes, the ASC8852AETK is fully pin-to-pin compatible with ASC8850AETK and ASC8851AETK in the TFBGA-484 package. This compatibility extends to signal mapping, power domains, and peripheral interfaces - enabling hardware reuse across product tiers. NXP confirms this in the ASC885xA selection guide and states it allows "easy design upgrades without the need for hardware modifications."
What video output standards does the ASC8852AETK support for local display or recording?
The ASC8852AETK supports 24-bit RGB, BT.1120, and BT.656 video outputs simultaneously. It delivers 1080p@60 fps over RGB and BT.1120 - enabling direct connection to HDMI transmitters or HD-SDI drivers - while BT.656 supports legacy LCD panels. This triple-output capability is specified in the ASC885xA technical documentation and is leveraged in ASC8852AETK-based DVRs and door stations.
