N32926U6DN

Video Processing Overview

The N32926U6DN is an ARM9-based System on Chip (SoC) microprocessor manufactured by Nuvoton Technology Corporation. It integrates an ARM926EJ-S core with a dedicated H.264 video codec for consumer video applications. The device features a 32-bit data bus, 8 kB L1 instruction cache, and 8 kB L1 data cache. It includes 32 MB of data RAM and operates at an I/O voltage of 3.3 V. The processor provides 80 general-purpose I/O pins, four timers, and a watchdog timer. Interfaces include GPIO, I2C, I2S, PWM, SPI, and UART. It is housed in a 128-LQFP (14x14 mm) surface-mount package.

Video Processing Procurement Notes

Verify component status before integration, as this part may be marked as not recommended for new designs due to potential minimum order quantity restrictions or lifecycle changes. Confirm the specific package variant matches the 128-LQFP requirement. Check RoHS3 compliance and moisture sensitivity level 3 handling requirements during assembly. Ensure supply chain availability aligns with project timelines given potential discontinuation risks.

Video Processing Selection Notes

Select this SoC when an integrated ARM9 solution with hardware H.264 decoding is required for video-centric applications. Consider the 32 MB RAM capacity and 3.3 V I/O voltage levels against system power and memory constraints. Evaluate the 128-pin LQFP footprint for PCB layout compatibility. Compare interface counts against peripheral requirements to ensure sufficient GPIO and communication channels are available without external multiplexing.

Video Processing Part Context

This component belongs to the Nuvoton N3292x series of ARM9-based multimedia processors. It is designed specifically for high-performance video processing tasks within embedded consumer electronics. The series emphasizes integrated codec functionality to reduce external component count and system complexity compared to discrete processor and decoder solutions.

Video Processing Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The related model N32926U4DN exists but differs in DRAM configuration (512Mb MCP vs. unspecified external/other configuration). Verify functional equivalence and pin compatibility if considering alternative SKUs from the same family.
