1810-DG-225-RI

Overview

The Critical Link MitySOM-1810F (Model 1810-DG-225-RI) is a System-on-Module featuring the Texas Instruments AM1810 ARM926EJ-S processor running at 375 MHz. It integrates an onboard Xilinx Spartan-6 FPGA (XC6SLX16), up to 256 MB mDDR2 RAM, and 512 MB NAND Flash. The module utilizes a standard SO-DIMM-200 interface for connectivity, including Ethernet, USB, and serial ports. Designed for industrial environments, it supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Xilinx Spartan-6 XC6SLX16 FPGA providing 96 configurable user I/O pins
• Memory configuration includes 256 MB mDDR2 RAM and 512 MB parallel NAND Flash
• Industrial temperature rating (-40°C to 85°C) with single 3.3V power supply

Applications

• Embedded Instrumentation
• Industrial Automation
• Medical Instrumentation
• Software Defined Radio
• Network Enabled Data Acquisition

Procurement Notes

Verify the specific ordering suffix RI confirms the industrial temperature range (-40°C to 85°C). Confirm availability status directly with Critical Link or authorized distributors as lead times may vary. Ensure baseboard design accommodates the SO-DIMM-200 connector pinout and provides necessary voltage levels for FPGA bank I/Os.

Selection Notes

Select this model when industrial temperature stability is required alongside hardware acceleration from the Spartan-6 FPGA. The 1810-DG-225-RI variant specifically offers the -40°C to 85°C range compared to the commercial RC version. Consider the 256 MB RAM limit for complex Linux or QNX workloads requiring significant memory footprint.

Part Context

This module belongs to the MitySOM-1810 family, which pairs the TI AM1810 Sitara processor with Xilinx FPGAs. The 1810-DG-225-RI is the industrial-grade counterpart to the 1810-DG-225-RC. Both share identical electrical specifications but differ in environmental tolerance ratings defined by their respective suffixes.

Replacement Considerations

No direct public substitute part numbers are documented. For legacy replacement, evaluate newer Critical Link SOMs based on processor architecture compatibility and form factor constraints. Verify if the target application can migrate from ARM9 to newer architectures without redesigning the carrier board.
