Description

The SBC-T3730 is a small single board computer based on the Texas Instruments DM3730 processor. It is implemented by a CM-T3730 module providing most of the functions, in combination with SB-T35 carrier board providing connectors and several additional features. The rich feature set of the SBC-T3730 is customizable according to the price / performance targets of the user's application.

DM3730 processor of SBC-T3730 combines two CPU cores in single package - an advanced Cortex-A8 ARM CPU for running operating system and application code, and TMS32064x DSP for dedicated video processing. Low voltage Mobile DDR enables very low power consumption in regular operation and in standby.

Power supply options of the SBC-T3730 enable its integration in mobile applications powered by a rechargeable battery. Charger and battery management support is provided on-board.

Specifications

• The "SB Option" column specifies the P/N code of SB-T35 carrier board required to have the particular feature. The "CM Option" column specifies the P/N code of CM-T3730 required to have the particular feature. SBC-T3730 content is the combination of features provided by the attached CM-T3730 and the features implemented on the SB-T35. To have the particular feature, both the CM and SB options of that feature must be implemented.
• "+" means that the feature is always available, regardless of P/N code.
