The MYD-AM335X Development Board designed by MYIR is a high-performance ARM Evaluation Module (EVM) using the MYC-AM335X CPU module as the core controller board. It is based on up to 1GHz Texas Instruments (TI) Sitara AM335x family of ARM Cortex-A8 Microprocessors (MPUs) that deliver high DMIPs at a low cost while also delivering optional 3D graphics acceleration and key peripherals. These TI Cortex-A8 MPUs include industrial interface options, such as EtherCAT and PROFIBUS, and can support the Linux, Android and Windows CE high-level operating systems. The combination of graphics and connectivity support makes TI AM335x MPUs ideal for home automation, industrial automation, enterprise/educational tablets, portable navigation devices and networking. The board can work in harsh environment supporting -40 to +85 Celsius extended temperature operation for industrial embedded applications.

MYD-AM335X Development Board

The TI AM335x consists of 6 pin-pin compatible devices (AM3352, AM3354, AM3356, AM3357, AM3358 and AM3359) with various options including speed grades, packages, graphics and peripherals. MYIR is using the 15x15 mm, 0.8-mm ball pitch, ZCZ package AM335x ARM CPU on the MYC-AM335X CPU Module which is an SOM (System on Module) and has the core components AM335x processor, 512MB DDR3 SDRAM, 512MB Nand Flash and Gigabit Ethernet PHY chip on board and can be served as the core of your embedded system. It has two 2.0mm pitch 60-pin male expansion connectors, one 2.0mm pitch 26-pin interface and one 2.0mm pitch 10-pin interface to allow extension of all the controller signals and ports to the base board through headers and connectors, thus exposing more features of the AM335x Cortex-A8 Processors.

MYC-AM335X CPU Module

The MYD-AM335X base board has extended many features and peripherals with the support of the MYC-AM335X SOM and some extended controller chips including two serial ports, four USB Host ports, one USB OTG port, dual Gigabit Ethernet ports, one CAN, one RS485, one Micro SD, HDMI, LCD, Touch screen and more others.

User can integrate a different MYC-AM335X SOM on the same base board, thus making six variants of AM335x evaluation boards.

Hardware Specification

The MYD-AM335X 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. MYIR deliveries the MYD-AM3352 and MYD-AM3358 by default according to customers specified model. Other four models are only available for mass quantity demand.

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.
  • The PRU-ICSS enables additional peripheral interfaces and real-time protocols such as EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, Ethernet Powerlink, Sercos, and others.
