Microprocessors Procurement Notes

Verify silicon revision compatibility, specifically regarding mask set 2.0.1 updates for USB-HS and SD/MMC boot modes. Confirm package type matches design requirements, as MAPBGA variants exist in different pitch sizes. Ensure supply voltage levels adhere strictly to non-overdrive or overdrive duty cycle limits defined in the electrical characteristics to prevent degradation. Check for regional import restrictions associated with specific BGA part numbers prior to ordering.

Microprocessors Selection Notes

Select this component when ARM11-based performance meets application needs without requiring newer architecture cores. Consider the integrated IPU and VFP co-processor if offloading video processing from the main CPU is critical. Evaluate thermal resistance parameters against board layout constraints, particularly for the 14 mm and 19 mm packages. Verify that the required peripheral interfaces, such as USB OTG and SDHC, align with system connectivity goals.

Microprocessors Part Context

This processor belongs to the i.MX 31 family of multimedia applications processors designed by Freescale Semiconductor. It represents a generation of low-power, high-performance chips optimized for portable digital devices. The family distinguishes between standard models with GPU support and 'L' variants which omit the graphics processing unit to reduce complexity and power consumption while retaining core multimedia capabilities.

Microprocessors Replacement Considerations

No direct public substitute part numbers are documented in the provided datasheet. Designers should evaluate newer NXP i.MX series processors for updated core architectures and interface support, ensuring software migration paths are viable for legacy codebases targeting the ARM11 platform.
