ASC8850AETE

Overview

The ASC8850AETE is a specialized application processor from NXP Semiconductors designed for high-definition IP camera systems. It integrates an ARM926EJ-S CPU core operating at 600 MHz with dedicated hardware engines for H.264, MPEG-4, and MJPEG video compression. The device supports up to 12 MPixel sensor inputs via 16-bit parallel interfaces and provides independent multi-stream encoding capabilities. Key technical specifications include two SDRAM channels supporting DDR-II/III memory up to 2 GB total capacity, integrated Ethernet MAC (10/100/1000), USB 2.0 OTG, PCIe, and multiple serial interfaces. Encased in a compact TFBGA-484 package measuring 15 x 15 mm, it delivers advanced image signal processing features such as 3D noise reduction and digital WDR.

• Industrial vision applications

Procurement Notes

Verify the specific ordering suffix 'AETE' against the manufacturer's current selection guide to confirm pinout and package compatibility. Confirm availability status as this component family may have reached end-of-life stages. Ensure that the required software development kit (SDK) and reference designs are accessible for integration. Check for any updated moisture sensitivity levels or labeling changes prior to procurement.

Selection Notes

Select the ASC8850AETE when system requirements demand 1080p @ 60 fps output or 12 MPixel sensor support. Compare performance metrics against the ASC884xA series if lower resolution targets suffice. Verify interface requirements for Ethernet, USB, and PCIe connectivity. Ensure the design accommodates the necessary external DDR memory configuration and power supply constraints associated with the 600 MHz operation.

Part Context

This component belongs to the ASC885xA family of integrated IP camera processors. It is part of a pin-to-pin compatible product line that includes variants like the ASC8848A, ASC8849A, ASC8851A, and ASC8852A. These devices share a common architecture but differ in CPU frequency, maximum sensor resolution, and video compression throughput capabilities.

Replacement Considerations

Pin-to-pin compatible alternatives within the same family include the ASC8851A and ASC8852A. These variants offer identical packaging and interface layouts but provide higher video compression performance metrics.
