PGA900: PGA900

user5006944
Intellectual 630 points

Part Number: PGA900

One, because there are films contained M0 chip, but I see the program storage is OTP, so inconvenient follow-up procedures to upgrade, I do not know there is no solution?

Second, if you do not use M0 microcontroller function (that is, in Reset mode), can achieve two-way data acquisition, temperature compensation (compensation level)?

Third, if you do not use M0 microcontroller function (that is, in Reset mode), can achieve the acquisition of data through I2C or SPI upload to the main chip? OWI for the receiver has additional decoding circuit requirements, not very convenient.

    Hello,

    The PGA900 includes 8kb of DEVRAM that can be used to test your firmware before committing it to the OTP memory. Once the OTP has been programmed it of course cannot be upgraded.

    All of the temperature compensation and pressure linearization algorithms will be implemented in the microcontroller, so that will not be available with it in reset.

    When the microcontroller is in reset, all of the digital interfaces are available for use to directly access the PGA900 memory locations. You will have to select which interfaces (SPI/I2C/OWI) are to be used with the MICRO_INTERFACE_CONTROL register.

    Regards,
