• ADuC834: Interfacing the ADuC834 to a RTD

    I've got two questions:
    1. Is there any performance difference between old RTD connection (in ADuC824
    datasheet with ref resistor connected to EXC) and new RTD connection (in
    ADuC834 datasheet with ref resistor connected to AGND)?
  • ADUC834 Flash/EE program memory security

    Dear 

    Please give a hand, for ADUC834,I will use the Secure Mode of ADUC834 of flash/EE,but there are two problems need to be solved,thanks.

    1.how to make sure the encryption is successful.

    2. when I download the program to Flash, the system promote the…

  • ADUC834 : Can I run this device from split supplies, 3.3V DVDD and a 5V AVDD?

    The ADuC834 has separate pins for analog and digital power supplies. Can I run
    from a split  supply, for example a 3.3V DVDD and a 5V AVDD?

     

    Yes, You may run the ADuC834 from split supplies. See the ADuC834 datasheet (pg
    67) for mor…
  • ADUC834: What external clocks can be used? Can the PLL be bypassed?

    What external clocks can be used with the ADuC834? Can the PLL be bypassed?

     

    The PLL circuit on the ADuC834 will lock to 384 times the input clock as long
    as the clock
    frequency is within the frequency range 32.768kHz ± 20%. The ADC incorporates…
  • ADuC834: pinout decriptions missing for CSP pins 28and 29

    Pin Function Descriptions are on the page 10 to page 12 of ADuC834 datasheet
    but there are no PIN 28, 29 description for CSP package.

     

    On ADuC834 CSP package:
    Pin28 is SCLOCK,
    Pin29 is SDATA/MOSI

  • Why does it take the ADuC834 so long to power on?

    Why does it take the ADuC834 so long to power on?

     

    Before the user code executes, the ADuC834 waits for the crystal to oscillate.
    This can take
    anywhere from under 1ms to over 300ms. See the ADuC834 datasheet (pg 6, REV A)
    for typical…
  • ADUC834: How do I configure the UART serial port at 9600/115200 baud?

    How do I configure the ADuC834 UART serial port at 9600/115200 baud?

     

    The UART serial port on the ADuC834 can be configured for 9600 baud using the
    following piece
    of code (assuming CD in PLLCON=3):
    MOV T3CON, #82h
    MOV T3FD, #1…
  • program code for ADuC834

    Does anyone have program code for ADuC834 for Tunable laser operation.??

  • ADUC834: What baud rates can be achieved?

    What baud rates can be achieved by the ADuC834? Can the ADuC834 achieve a baud
    rate of
    115200 baud when used with a standard 32.768kHz watch crystal. How is this
    done?

     

    The ADuC834 can achieve baud rates up to 393kbaud. In terms of…
  • ADUC834: Do I need external reset generator?

    Will I need to implement an external reset generator circuit for my ADuC834
    design?

     

    No, you will not have to implement an external reset generator. The ADuC834 has
    an integrated
    robust power on reset circuit. The pin can be left…
