ASC8850ET/M2,551

Overview

The ASC8850ET/M2,551 is a single-chip system-on-chip (SoC) designed for full HD IP camera applications. It integrates an ARM926EJ-S CPU running at up to 600 MHz with dedicated hardware for image processing and video compression. The device supports up to 12 MPixels raw data input and performs digital WDR, noise reduction, and auto-exposure adjustments. It compresses video into H.264, MPEG-4, or MJPEG formats via integrated encoders. Connectivity includes a 10/100/1000 Ethernet MAC, USB 2.0 OTG, PCIe 1.1, and multiple peripheral interfaces. Memory support extends to 2 GB of SDRAM across two channels.

Feature Summary

• ARM926EJ-S processor operating at 600 MHz with 16 KB I-Cache and D-Cache
• Hardware video compression supporting H.264 (up to 1080p @ 45 fps), MPEG-4, and M-JPEG
• Advanced image signal processing including digital WDR, noise reduction, and lens distortion correction
• Integrated security engine supporting AES, TDES, DES, and SHA cryptographic algorithms

Applications

• Security IP cameras
• Video conferencing systems
• Video door phones and intercoms
• Industrial vision systems

Procurement Notes

Verify the specific suffix 'M2,551' against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing Linux 2.6 software development kits and reference designs provided by NXP for this product family.

Selection Notes

Select the ASC8850ET/M2,551 when high-resolution sensor support (up to 12 MPixels) and multi-stream encoding are required. Compare performance metrics against the ASC8851 if higher frame rates at 1080p are needed, as the ASC8850 supports up to 30 fps at 1080p in H.264 baseline mode.

Part Context

This component belongs to the ASC884x and ASC885x family of NXP SoCs. These devices are pin-to-pin and software-compatible, allowing for design flexibility within the same product line. The family targets the transition from analog to digital switched networks for security and communication applications.

Replacement Considerations

The ASC8851 serves as a functional alternative within the same family, offering higher single-stream video compression performance. Both devices share identical packages and interface configurations, facilitating direct substitution in compatible designs.
