3354-HX-XX8-RC

Overview

The Critical Link MitySOM-3354-HX-XX8-RC is a System on Module (SOM) based on the Texas Instruments AM3354 processor. It features an ARM Cortex-A8 core running at 800 MHz with a NEON SIMD coprocessor. The module integrates 512 MB of DDR3 RAM and utilizes a standard SO-DIMM-204 interface for connectivity. It operates within a commercial temperature range of 0°C to 70°C. This configuration excludes onboard NAND or NOR flash storage, relying instead on external memory via the General Purpose Memory Controller (GPMC).

Feature Summary

• Processor: TI AM3354 with ARM Cortex-A8 CPU at 800 MHz.
• Memory: 512 MB DDR3 RAM; no onboard NAND/NOR flash.
• Interface: Standard DDR3 SO-DIMM-204 connector.
• Temperature Range: Commercial grade (0°C to 70°C).

Applications

• Embedded Instrumentation
• Industrial Automation
• Medical Instrumentation

Procurement Notes

Verify the specific revision level of the AM335x silicon when ordering, as Revision 1.0 limits maximum frequency to 720 MHz. Confirm that the target application can support external memory booting, as this model lacks onboard NAND or NOR flash. Ensure the host carrier board provides the necessary power supply and signal routing for the SO-DIMM-204 interface.

Selection Notes

Select this model when a cost-effective solution with 512 MB DDR3 is required without onboard non-volatile storage. It is suitable for designs where external GPMC-connected memory is preferred or already present on the carrier board. Choose alternative models like the 3354-HX-X38-RC if onboard 512 MB NAND flash is needed for standalone booting capabilities.

Part Context

This part belongs to the MitySOM-335x series, which offers various configurations of the AM335x family. The 'HX' designation typically indicates an 800 MHz speed grade, while 'XX8' denotes the absence of onboard NAND/NOR flash but presence of 512 MB DDR3. The 'RC' suffix specifies the commercial operating temperature range.

Replacement Considerations

For direct functional replacement with identical pinout and memory specs, consider the 3354-HX-X38-RC, which adds 512 MB NAND flash. For higher performance, the 3354-IX-X3A-RC offers 1 GHz operation and 1 GB DDR3.
