The module includes NAND FLASH and DDR2 or DDR3 RAM memory subsystems. A MitySOM-335x provides a complete and flexible CPU infrastructure for highly integrated embedded systems. 1 Copyright © 2018, Critical Link LLC Specifications Subject to Change Critical Link, LLC www.CriticalLink.com MitySOM MitySOM-335x Processor Card 9 February 2018 The onboard AM335x processor provides Cortex-A8 32-bit RISC processor with a NEON SIMD coprocessor. This MPU is capable of running a rich set of real-time operating systems containing software applications programming interfaces (APIs) expected by modern system designers. The ARM architecture supports several operating systems, including Linux, QNX, and Windows CE. In addition to the Cortex-A8, the AM335x family also offers available dual Programmable Real-Time Units (PRUs) when using the AM3356, AM3357, AM3358 or AM3359 processors. These PRUs are 200MHz RISC processors that run independently of the main Cortex-A8 CPU and have access to all the on-chip peripherals as well as all external memory. These can be used for any purpose; typical applications include the implementation of custom, industrial serial or Ethernet protocols such as PROFIBUS or EtherCAT. In addition, the PRUs can continue to run while the core CPU is in sleep mode in order to monitor for system wakeup events. Figure 1 MitySOM-335x Block Diagram Figure 1 provides a top level block diagram of the MitySOM-335x processor card. As shown in the figure, the primary interface to the MitySOM-335x is through a standard DDR3 SO-DIMM-204 card edge interface. The interface provides power, synchronous serial connectivity, and many other interfaces provided by the Sitara processor. Details of the SO-DIMM-204 connector interface are included in the SO-DIMM-204 Interface Description, below. 2 Copyright © 2018, Critical Link LLC Specifications Subject to Change Critical Link, LLC www.CriticalLink.com MitySOM MitySOM-335x Processor Card 9 February 2018 MitySOM-335x Onboard DDR Memory Options DDR2 Memory Option The AM335x processor includes one dedicated 16 bit DDR SDRAM memory interface. The MitySOM-335x can include up to 256 MB of DDR2 RAM integrated on board the module. The memory bus interface is capable of burst transfer rates of 800 MB / second. DDR3 Memory Option The AM335x processor includes one dedicated 16 bit DDR SDRAM memory interface. The MitySOM-335x includes up to 1 GB of DDR3 RAM integrated on board the module. The memory bus interface is capable of burst transfer rates of 1200 MB / second. MitySOM-335x Onboard Storage Memory NAND FLASH (Optional) Up to 1GB of on-board NAND FLASH memory is connected to the AM335x processor using the general purpose memory controller (GPMC) bus. The FLASH memory is 8 bits wide and is connected to the first chip select line of the GPMC (CSN0 – AM335x Ball V6). The FLASH memory is typically used to store the following types of data: - Bootloaders ARM Linux / Windows CE / QNX embedded root file-system runtime ARM software runtime application data (non-volatile storage) The GPMC bus is also accessible on the SO-DIMM-204 connector. It can be used to access external memories such as SDRAM, SRAM, NOR flash, NAND flash, or memory-mapped ASICs and FPGAs. The inteface is a maximum of 16-bits wide, but can also be used for 8-bit access. NOR FLASH (Optional) Up to 16 MB of on-board NOR FLASH memory is connected to the AM335x using the Serial Peripheral Interface (SPI1 NOR CS0 – AM335x Ball C12). The AM335x provides up to 2 SPI interfaces with both interfaces available on the SO-DIMM connector. Configuration EEPROM The MitySOM-335x contains a 256 x 8-bit EEPROM that is used to hold configuration data for the module. The EEPROM is connected to the AM335x using the I2C1 interface at address 1010XXXb (0x50 to 0x57). 3 Copyright © 2018, Critical Link LLC Specifications Subject to Change Critical Link, LLC www.CriticalLink.com MitySOM MitySOM-335x Processor Card 9 February 2018 External Interfaces The AM335x makes extensive use of functional pin multiplexing to provide a highly configurable device that can be tailored to a multitude of applications.

- - Note 1: The PowerOn pin (32) has a pull-up resistor on the module so it can be left floating if user control is not desired. Note 2: Please reference Table 2 for information on the maximum current supply of these voltage outputs. Note 3: These signal mux options are only available in Revision 2.0 or higher AM335x Silicon. Note 4: I2C1 and I2C2 are used by devices on the module and therefore should not be muxed to other AM335x pins. The Power Management IC (PMIC) on the all MitySOM-335x modules utilize I2C1 at address 0x12 and I2C2 at address 0x2D. 10 Copyright © 2018, Critical Link LLC Specifications Subject to Change Critical Link, LLC www.CriticalLink.com MitySOM MitySOM-335x Processor Card 9 February 2018 ELECTRICAL CHARACTERISTICS Table 2: Electrical Characteristics Parameter Conditions Symbol Min Typ Max Units 3.2 3.3 5.2 Volts 500 500 mA mA VIN Voltage supply, volt input.
