• Provides dual 10/100 Mbps Ethernet MAC controllers and two sets of CAN interfaces for robust industrial communication.
• Supports flexible system boot sources including SPI Flash, NAND Flash, eMMC, and USB Device.
• Features a 24-bit LCD controller supporting RGB565/RGB666/RGB888 interfaces for high-resolution display applications.

Microprocessors Applications

• Industrial automation control systems
• Human-machine interface (HMI) devices
• Display applications requiring integrated memory and processing

Microprocessors Procurement Notes

Verify the specific suffix 'IEC' corresponds to the industrial temperature grade (-40°C to +85°C) and the 216-pin LQFP package configuration. Confirm that the 64 MB DDR2 memory integration matches the design requirements. Check for moisture sensitivity level compliance during handling. Ensure the supplier provides official datasheets confirming the ARM926EJ-S core specifications and interface availability.

Microprocessors Selection Notes

Select this component when a single-chip solution combining an ARM9 processor with substantial onboard memory is required to minimize board space. It is suitable for designs needing multiple communication protocols like dual Ethernet and CAN without external controllers. Consider the 216-pin footprint and thermal characteristics for industrial environments. Compare against variants with lower memory capacities if cost or pin count constraints exist.
