3354-HX-X38-RC

Overview

The Critical Link 3354-HX-X38-RC is a System on Module (SOM) within the MitySOM-335x series, featuring a Texas Instruments AM3354 processor. It integrates an ARM Cortex-A8 core operating at up to 800 MHz with a NEON SIMD coprocessor and SGX530 3D graphics accelerator. The module provides 512 MB of DDR3 RAM and 512 MB of NAND flash memory via a standard SO-DIMM-204 interface. Electrical characteristics include a 3.3V nominal input voltage range of 3.2V to 5.2V, with commercial temperature operation from 0°C to 70°C.

Feature Summary

• AM3354 Processor: ARM Cortex-A8 MPU running up to 800 MHz with integrated NEON SIMD and SGX530 3D graphics.
• Memory Configuration: Includes 512 MB DDR3 system RAM and 512 MB parallel NAND flash storage.
• Standard Interface: Utilizes a 204-pin SO-DIMM card edge connector for power and high-speed data connectivity.
• Peripheral Support: Provides dual Gigabit Ethernet MACs, dual USB 2.0 OTG ports, six UARTs, two CAN interfaces, and multiple SPI/I2C buses.

Applications

• Embedded Instrumentation
• Industrial Automation
• Medical Instrumentation
• Closed Loop Motor Control

Procurement Notes

Verify the specific revision level of the silicon when sourcing this component, as TI AM335x Revision 1.0 limits maximum frequency to 720 MHz, whereas later revisions support higher speeds. Confirm that the required memory configuration matches the 512 MB DDR3 and 512 MB NAND specification listed in the ordering table. Ensure compatibility with the commercial temperature range (0°C to 70°C) if industrial ratings are not explicitly required for the deployment environment.

Selection Notes

Select the 3354-HX-X38-RC when the application requires the AM3354 processor variant with 3D graphics acceleration but does not necessitate the Programmable Real-time Units (PRUs) found in the AM3356/57/58/59 families. This model is suitable for designs needing 800 MHz processing performance with standard DDR3 memory interfaces. Compare against the 3354-IX-X3A series if an industrial temperature range (-40°C to 85°C) is required instead of the commercial range.

Part Context

This part belongs to the MitySOM-335x family of highly configurable processor cards designed by Critical Link LLC. These modules serve as complete CPU infrastructure solutions, integrating the TI Sitara AM335x processor with necessary memory subsystems. The product line supports rapid development through standardized interfaces and comprehensive software development kits compatible with Linux, QNX, and Windows CE operating systems.

Replacement Considerations

For pin-compatible alternatives within the same form factor, consider the 3354-HX-X38-RI for industrial temperature ranges or the 3354-IX-X3A-RC for higher speed grades. If PRU functionality is required, the AM3359-based 3359-GX-226-RC is a functional alternative within the same series, though it operates at a lower base frequency.
