除了你可以使用一个外部的OTPSPI flash memory or an EEPROM, there are a few supported by dialog that you can find in the document AN-B-023 document on page 21. You can use Smart Snippets in order to burn your external modules.
What do you mean the circuitry of the OTP flashing, you can flash the OTP by using Smart Snippets.
The retention RAM is 8K in total and when the 580 is not powered it doesn't retain the data, if you dont want to use an external memory (flash, eeprom) the only memory you can burn your code is the OTP.
I mean the connections and supply voltage from J-Link to PAN1740 for OTP flashing. And also in the data sheet of PAN1740 USB stick, it says OTP programming is not supported. If we want to go into production, What is the solution? How to design our own flashing circuitry?
You only need the 6.8V vpp in order to burn the 580's OTP, please check the following link for the required connections of the JTAGhttp://support.dialog-semiconductor.com/guide/faq-dev-kits-ref-designs. Regarding the fact that the OTP burning is not supported by the Panasonic dongle i am not aware of this, as far as i can tellfrom the documentation of the PAN,panasonic uses this feature for security reasons in order not to damage the OTP of the dongle. Checked with panasonic there is no way to bypass this feature of the USB dongle.
Thank you that was helpful. Which of the PAN module should I buy in order to evaluate the OTP flashing as per the above link? Can I use the SPI flash on the DA14580 Eval board to boot the PAN1740 module? How to do this if possible?
Regarding the Panasonic modules, as far as i know you will need to get the dialog pro mother board and the corresponding PAN modules that attach on the pro kit in order to evaluate the product. Through smart snippets you are going to be able to burn the OTP. Please check the panasonic_pan1740_design_guide.pdf for more information.
Regarding the booting from the SPI flash, yes its possible to do so (not with the PAN dongle since it doesn't have an on board flash). Dialog's pro kit motherboard has an SPI flash on board you can connect P00(CLK)/P03(CS)/P05(MISO)/P06(MOSI) via jumpers on the J5 header, and burn your image in the flash.
Hi Bharath,

Thanks MT_dialog
Where can I get the circuitry for OTP flashing?
Is it possible to flash my code onto Retention RAM?
Thank you
