    Our customer make first their evaluation board (ES1 board), and they started evaluation their ES1 board.

    Currently, they validate power up/down sequence, unfortunately VDD_INT and VDD_EXT power up/down sequence are not same time as below.

  • RE: ADSP-BF700 GPIO pins impedance

    Hi,

    During power-up reset, all pins are high impedance except for those noted in the ADSP-BF70x Designer Quick Reference. Please refer ADSP-BF700 datasheet from the below link for more information.

  • I need a reference circuit for using the ADSP-BF700 series  processors

    In the ADSP-BF700 series data sheet I find that the GPIO pins can be multiplexed using two bits. According to the values of those two bits each GPIO pin is connected to four different signals.

    I am designing a 24 GHz radar and I have selected the ADSP…

  • ADSP-BF700 : Trying to move a function into L@ RAM - Working?

    I am trying to prove that I can move a function from regular L1 memory to L2 RAM on the BF700.  I looked at the following .PDF manual to see what to do. I am putting a "#pragma section ("L2_sram")" before a function.

  • Write ADV7625  via BF700

    with AVES3, write data to ADV7625, It's OK and i can find all  Register Maps and I2C Addresses (In I2C Bus, there are 40 of devices can be connected):

         the Address are: 0x20/0x21(W/R, this is my another device),
