DMC (CY7C65219-40LQXI) also follows the same SWD programming procedure as the DMC controller in HX3PD so the programming specification that can be followed is- https://www.cypress.com/file/479596/download
Please note that the Silicon ID will be different and can be obtained from the DMC datasheet.
Hello Sananya san
Based on the document, I think it is possible to program HEX files to the internal Flash of CY7C65219 using the SWD pins, and it is possible for a PSoC programmer to program HEX file using Miniprog3, is that correct?
Or is it necessary for the user to create a programming FW according to "4. Programming Algorithm" from an external CPU via the SWD pin?
Yes, that is correct. The .hex file generated by PSoC Creator can be directly programmed using MiniProg3 on the SWD pins through PSoC Programmer. You could also refer to Page 9 of the DMC datasheet for the same description- https://www.cypress.com/file/402646/download
