ASC8850AETK

Overview

The ASC8850AETK is a specialized application processor manufactured by NXP Semiconductors, designed for high-definition video surveillance and IP camera applications. It integrates an ARM926EJ-S core operating at a maximum clock frequency of 600 MHz with a 32-bit data bus width. The device features 16 kB L1 instruction cache and 16 kB L1 data cache. Packaged in a 484-pin TFBGA format for surface-mount installation, it supports interfaces including Ethernet, I2S, SPI, UART, and Video. This component functions as a single-chip solution for capturing raw sensor data, performing image signal processing, and compressing video to H.264 standards.

Feature Summary

• Integrated ARM926EJ-S processor core running up to 600 MHz
• Supports Full HD (1080p) video compression at 30fps using H.264
• Includes Image Signal Processor (ISP) with 3A functions (Auto Exposure, Auto White Balance, Auto Focus)
• Provides multiple connectivity options including Ethernet, USB OTG, SPI, and UART

Applications

• High-definition IP cameras
• Network video recorders (NVR)
• Video surveillance systems requiring real-time H.264 encoding

Procurement Notes

The ASC8850AETK is listed as a discontinued product by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than standard distribution channels. Buyers must confirm the specific revision status and ensure compatibility with existing firmware architectures before procurement, as end-of-life components may have limited long-term supply support.

Selection Notes

Select this component for designs requiring a dedicated hardware encoder for 1080p H.264 video streams within a compact footprint. The ARM926EJ-S core provides sufficient processing power for basic network protocols and ISP tasks but lacks the multimedia acceleration found in newer Cortex-A series processors. Ensure the design accommodates the 484-TFBGA package requirements and verifies that the required peripheral interfaces (Ethernet, USB OTG) align with the system's connectivity needs.

Part Context

The ASC8850AETK belongs to the NXP ASC88xxA family of System-on-Chips (SoCs) specifically engineered for digital video surveillance. This family represents a transition from discrete component solutions to highly integrated single-chip platforms capable of handling raw CMOS sensor input directly. The ASC8850 variant targets Full HD resolutions, distinguishing itself from lower-resolution predecessors like the ASC884x series by supporting higher bandwidth video compression standards.

Replacement Considerations

As the ASC8850AETK is discontinued, direct functional replacements are not explicitly documented in public datasheets. Designers should evaluate newer NXP SoC families such as the i.MX series or Vybrid series for updated performance and security features. Migration requires significant redesign of the board layout due to differences in pinouts, voltage levels, and software drivers.
