The MYD-AM335X-J development board is a complete evaluation platform for TI AM335x (AM3352, AM3354, AM3356, AM3357, AM3358 and AM3359) ARM Cortex-A8 Sitara Microprocessors (MPUs). It is designed based on the MCC-AM335X-J CPU module which integrates the core components on board including the AM335x processor, 256MB DDR3, 256MB Nand Flash, Gigabit Ethernet PHY, PMIC, etc.

The MCC-AM335X-J CPU Module is mounted onto the MYD-AM335X-J base board through an SO-DIMM 200-pin gold finger interface. In addition to those main functions provided by the MCC-AM335X-J CPU module, the MYD-AM335X-J base board has extended more functions through headers and connectors, which makes the board versatile for various industrial applications. It features up to six serial ports, two Ethernet ports, USB Host, OTG, CAN, RS485, TF card slot, Audio, LCD and more other peripherals on board. It can support -40 to +85 Celsius extended temperature operation and ready to run Linux operating system.

MYD-AM335X-J Development Board

User can integrate a different MCC-AM335X-J module on the same base board, thus making six variants of evaluation boards. The differences are depending on the AM335x processor features with various options including speed grades, packages, graphics and peripherals. The image below gives a brief overview of options.

The MYD-AM335X-J board comes with Linux 3.2.0 software packages, detailed documents, necessary cable accessories as well as optional 4.3-inch or 7-inch LCD (with touch screen) Module, WiFi, Camera, GPS and GPRS modules to enable your rapid development when getting the goods out-of-the-box.

Hardware Specification

The MYD-AM335X-J series ARM Cortex-A8 boards have many features in common only with some differences depending on the AM335x Cotex-A8 CPU features. You can get to know the differences and more features of the AM335x series processors from below table.

The TI AM335x microprocessors, based on the ARM Cortex-A8, operating at up to 1GHz, are enhanced with image, graphics processing, peripherals and industrial interface options such as EtherCAT and PROFIBUS. The device supports the following high-level operating systems (HLOSs) that are available free of charge from TI:

• Linux?
• Android™

The AM335x microprocessor contains these subsystems:

• Microprocessor unit (MPU) subsystem based on the ARM Cortex-A8 microprocessor.
• POWERVR SGX™ Graphics Accelerator subsystem for 3D graphics acceleration to support display and gaming effects.
• The Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) is separate from the ARM core, allowing independent operation and clocking for greater efficiency and flexibility.
