PGA900: Programming an already build in PGA900 with evaluation board and software

Kolja Erbacher

Part Number: PGA900

Hi team,

i’d like to use the PGA900 for temperature compensation of a pressure sensor.

Is it possible to use the evaluation board and the software to programm an already build in PGA900 (PCB with IC in an case) via UART?

Thanks Kolja

    Hi Kolja,

    To program the OTP memory you will also need to have access to the VP_OTP pin to pull it up to 7.5 volts for the programming procedure. Typically in a production environment the PGA900 will be programmed before it is assembled as part of the final system. From there, interface is done usually through OWI since it requires no extra lines for communication.

    Regards,
