MSP430F2618: Microcode in MSP430

Part Number: MSP430F2618

Hi, it doesn't seems like it does, but can you please confirm that MSP430F2618 does not contain any microcode as meantioned in EASA AMC 20-152A, see below: "

Objective COTS-3

When the complex COTS device is used outside the limits of the device manufacturer’s specification (such as the recommended operating limits), the applicant should establish the reliability and the technical suitability of the device in the intended application.

6.4.1.2 Considerations when the COTS Device has Embedded Microcode

COTS devices may need microcode to execute some hardware functions. When those functions are used by the applicant, there is a risk if the microcode has not been verified by the device manufacturer during the COTS device qualification, or if the microcode is proposed to be modified by the applicant.

If the microcode is delivered by the device manufacturer, is controlled by the device manufacturer’s configuration management system, and is qualified together with the device by the device manufacturer, it is accepted that the microcode is part of the qualified COTS device. If the microcode is not qualified by the device manufacturer or if it is modified by the applicant, the microcode cannot be considered to be part of the qualified COTS device.

Objective COTS-4

If the microcode is not qualified by the device manufacturer or if it is modified by the applicant, the applicant should ensure that a means of compliance for this microcode integrated within the COTS device is proposed by the appropriate process, and is commensurate with the usage of the COTS device.

Note: The PHAC (or any other related planning document) should document the existence of the microcode and refer to the process (hardware, software, system) where it is addressed." Regards//Jonas Bjork

  • Hi Jonas,
    The MSP430F2618 is a hardware-centric device. Its primary functional logic is implemented in silicon (hardware), and it does not utilize a layer of non-qualified, user-modifiable, or "black box" microcode to execute its standard instruction set or hardware peripheral functions.
