AM6441: Part number definition

Part Number: AM6441

Hello TI team,

The newest design I'm developing is based on AM6441 Sitara Processor. At the moment I have to provide to our EMS the exact part number to mount on my PCBs, and I have a couple of questions in order to define it:

  1. In the field "f" of the nomenclature I have to choose between value E (ICSS + EtherCAT HW Accelerator + CAN-FD Enabled) and F (ICSS + EtherCAT HW Accelerator + CAN-FD + Pre-integrated Stacks Enabled) but I have no idea about what advantage could I have if I choose the pre-integrated stack option.
  2. Similar to the previous point, but regarding field y "Functional safety". If I mount a non-functional safety device, which features do I loose or which risks can I possibly face?
  3. Once in the field y "Security" I choose H (i.e HS device and not a GP device), I know there are two sub-types for high secure devices, the Field Securable (FS) and the Security Enforced (SE). How can I select one of them in the part number?

So said, can you check if I correctly understood the nomenclature? See below:

AM6441ASEFHAALV: it means AM6441 device , speed grade 1GHz for  A53SS , ICSS + CAN-FD enabled, functional-safe, security (HS device)

AM6441ASEFGAALV: it means AM6441 device , speed grade 1GHz for  A53SS , ICSS + CAN-FD enabled, functional-safe, no security (GP device)

Is it right?

Thank you for your help.

    The third letter after the digits is primarily for ICSS based networking and industrial protocols. D means ICSS networking is present and firmware from TI will run. E means EtherCAT Slave Controller (ESC) capability is present, TI firmware will run and EtherCAT stacks from third parties such https://www.ethercat.org/en/products/54FA3235E29643BC805BDD807DF199DE.htm will run. F means the stacks that are part of TI MCU+ SDK industrial toolkit will run. The app report https://www.ti.com/lit/pdf/sprach6 is in the process of having a major update to clarify these. Orthogonal to the industrial protocols, CAN-FD feature is similarly tied to part numbers, you need E or F to have CAN-FD.

    The Safety manual, Analysis report, diagnostic library, FMEDA, any certifications apply for the functional-safe parts. Building blocks used in these, like memory ECC are still present, but not necessarily tested to the quality documented for the functional-safe parts.

    If you have an FAE supporting you, I suggest you work with them to get access to the secure device documentation. We have streamlined the the process and you should just choose H.
