I need to know Programming spec of PGA450-Q1. How can I find it?

    Ted,

    Can you elaborate on what you mean by Programming spec? The datasheet has information on how to program the device, but do you need more specific information?

    Ted,
    Please refer to section 7.3.15.2 OTP Memory for Program of the PGA450-Q1 datasheet.

    Note, to program the PGA450-Q1's internal 8051, SPI must be used since UART/LIN are strictly reserved for communication only. Alternatively, PGA450Q1EVM+TIGER board combination can be used for small scale developmental programming, or the Acroview AP8000 mass production tool can be purchased at: www.acroview.com/.../302.html . Both of these platforms do not require you to write additional code for programming the PGA450-Q1.

    Hi Akeem,

    Lot's of questions about programming:
    Is the PGA450 chip already programmed when we buy it?
    Otherwise how can we program it? Is it possible to program this chip with J-Link SPI flasher?
    You talk about Ap8000 but wher can we find information to buy it? Is it interresting to buy it just for less than 100pcs?
    Is it possible to buy TIGER board without EVM?

    Thanks for answers.

    Hello b gaboriaud,

    The PGA450-Q1 is not programmed by default. You have the option of programming the DEVRAM or OTP memory. However, once you've decided on which memory space to program, you cannot switch to the other on the same IC. For this reason, DEVRAM is typically recommended for initial development and debug purposes, while OTP should be reserved for mass-production purposes.
    The two means of programming the PGA450-Q1 are:
    1) Use the PGA450Q1EVM, which contains a socket that allows you to quickly swap multiple ICs for programming.
    2) Use the Acroview AP8000. You can contact sales@acroview.com for details on purchasing or renting a unit for 100pcs programming.

    The TIGER board cannot be purchased separately. You must purchase the PGA450Q1EVM to obtain the TIGER board.
