It operates on a 3.3 V supply voltage within a temperature range of -40°C to +85°C. Connectivity options include Ethernet, WiFi, USB, CAN, I2C, SPI, UART, GPIO, PWM, and 1-Wire interfaces.

Feature Summary

• Built on the Atmel SAM9X35 ARM9 processor core operating at 400 MHz
• SO-DIMM package format measuring 67.49 mm x 32.05 mm
• Integrated 128 MB RAM and 4 MB Flash memory
• Supports Microsoft .NET Micro Framework software environment

Applications

• Industrial automation controllers requiring embedded computing
• IoT gateways utilizing integrated WiFi and Ethernet connectivity
• Embedded systems development platforms for .NET Micro Framework
• Commercial equipment needing wide industrial temperature operation (-40°C to +85°C)

Procurement Notes

Verify component status before integration as the G400D-SM-400 is designated NRND (Not Recommended for New Designs). Confirm availability through authorized distributors, noting that stock levels may be limited or subject to specific order quantities. Ensure compliance with RoHS requirements by checking detailed certification documents provided by the manufacturer.

Selection Notes

Select this module when a compact SO-DIMM footprint is required alongside ARM9 processing capabilities. Consider the 128 MB RAM limit for application complexity. Verify that the target operating system supports .NET Micro Framework. Evaluate interface needs against the available peripherals including CAN bus and multiple serial ports.

Part Context

This part belongs to the GHI Electronics G400 series of System-on-Modules. It shares the same processor and core specifications as the G400S-SM-480 but differs in physical packaging, with the G400D utilizing a standard SO-DIMM connector rather than surface-mount assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative modules from other manufacturers or newer generations within the GHI portfolio should be evaluated for long-term supply stability.
