5749-PM-4AA-RI

Overview

The 5749-PM-4AA-RI is a microprocessor module manufactured by Critical Link LLC, part of the MitySOM family. It integrates an ARM Cortex-A8 processor (AM3352) operating at a clock speed of 800 MHz. The module provides 256 MB of data RAM for system operations. Designed for industrial environments, it supports a wide operating temperature range from -40°C to +85°C. The hardware is housed in a compact form factor measuring 67.60 mm x 38.10 mm and utilizes a SO-DIMM 204 connector interface for board integration.

Feature Summary

• ARM Cortex-A8 processor core with NEON SIMD and DSP capabilities
• Integrated 256 MB data RAM
• Industrial temperature rating (-40°C to +85°C)
• SO-DIMM 204 connector interface

Applications

• Industrial automation controllers
• Medical device processing units
• Ruggedized embedded computing systems

Procurement Notes

Verify the specific revision suffix against the manufacturer's current documentation to ensure compatibility with required software BSPs. Confirm that the SO-DIMM 204 pinout matches the target carrier board design specifications before procurement.

Selection Notes

Select this module when a low-power ARM Cortex-A8 solution with integrated memory is required for space-constrained applications. Ensure the host system can support the 800 MHz processor speed and provide adequate thermal management within the specified -40°C to +85°C operational envelope.

Part Context

This component belongs to the Critical Link MitySOM series, which focuses on System-on-Module solutions based on Texas Instruments processors. The 5749-PM-4AA-RI specifically targets applications requiring reliable MPU performance in harsh environments, distinguishing itself through its ruggedized temperature range and standardized connector interface.

Replacement Considerations

Direct replacements are limited due to the proprietary module form factor. Evaluate other MitySOM variants from Critical Link or similar SOMs from vendors like Kontron or Advantech if the carrier board design allows for mechanical and electrical adaptation.
