ASC8852AETK

Overview

The ASC8852AETK is a specialized application processor from NXP Semiconductors designed for high-definition IP camera systems. It integrates an ARM926EJ-S CPU operating at 600 MHz with dedicated hardware engines for H.264, MPEG-4, and MJPEG compression. The device supports up to 12 MPixel sensors via a 16-bit parallel interface and provides independent multi-stream encoding capabilities. Key specifications include support for 1080p video at up to 65 fps in H.264 High Profile, two SDRAM channels supporting DDR-II/III, and comprehensive connectivity interfaces including Gigabit Ethernet, USB 2.0 OTG, PCIe, and multiple I2S audio channels.

Feature Summary

• High-performance H.264 compression engine supporting up to 1080p @ 65 fps or D1 @ 390 fps with ROI encoding and SVC-T scalability.
• Integrated ARM926EJ-S CPU running at 600 MHz with 16 KB instruction and data caches.
• Advanced image signal processing pipeline featuring 3D noise reduction, edge enhancement, motion adaptive de-interlacing, and digital WDR.
• Dual SDRAM memory channels supporting up to 1 GB DDR-III or 512 MB DDR-II per channel at 400 MHz.

Applications

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

Procurement Notes

Verify component authenticity through authorized NXP distributors. Confirm the specific ordering suffix matches the required package and temperature range. Check current availability status as this model may be subject to lifecycle changes. Ensure compliance with RoHS and REACH regulations relevant to the manufacturing date. Validate that the supply chain source provides original manufacturer documentation.

Selection Notes

Select the ASC8852AETK when maximum video throughput is required within the ASC885xA family, specifically for 1080p @ 65 fps H.264 performance. Compare against lower-frequency variants like the ASC8850A if power consumption or cost constraints allow for reduced frame rates. Ensure the design accommodates the TFBGA-484 package dimensions and thermal requirements. Verify software SDK compatibility with the target Linux 2.6 environment.

Part Context

The ASC8852AETK belongs to the ASC885xA series of integrated IP camera processors. This family offers pin-to-pin compatibility with previous generations such as the ASC884xA and ASC8850A, facilitating design upgrades without hardware modifications. It serves as the highest-performance variant in this specific lineup, targeting demanding full HD surveillance and recording applications requiring advanced image processing and high bitrate efficiency.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the ASC8851A and ASC8850A, though these offer lower maximum frame rates. Cross-family migration requires careful review of interface pinouts and software driver compatibility. No other manufacturers are confirmed as direct substitutes based on available public documentation.
