I'm using a STM32F103RCT6Flash contains my own boot loader in pages 0 thru 10 and main application in 11 thru 61.When the device is flashed in manufacturing, protection is set to prevent reading and writing via the jtag port.I need to update the boot...

I want to use a STM32G4 device in a new project but I was disappointed to find the USB implementation only supported Device mode.What is the hardware (implemented in the MCU) that make it capable of host mode from device mode (OTG supports both)? Wi...

Currently have a STM32F103 running HSE + pll with a SysClk of 72 mhz.I want to use one of the upper flash memory blocks for storing application information - which means I need to erase and program the flash memory from my application (I do this all ...

If you are NOT using USB with the STMH745 - what is best practice - Connect both the 5 and 3.3 USB power pins to 3.3v or leave them unconnected?

I don't use the internal Step Down regulator. How should the pins be tied?Should VDDSMPS be tied to VDD and VSSSMPS to GND with VLXSMPS and VFBSMPS left open?OR - should they ALL be left open?Documentation only speaks as if they are to be used - no c...

Thanks for the replies.The H series only has 1 opamp - I need 3.If spent hours looking thru the Series/features - the only mix analog/digital MCUs with 3 opamps that can be used as front ends to ADCs is the G series and they only support USB Device -...

Thanks for the reply. I was looking/hoping for a mcu that had BOTH USB Host mode and OP Amps that worked with the ADCs. No such luck with the STM32G4 family.

Yes - Thank You!

The Clock tree diagram shows the HSI directly feeding the Flash Controller - as noted above - for a known and constant clock source. I will attempt to erase/flash at 72 mhz.

I was hoping to get some insight before I started experimenting.Not difficult to set HSI ON and proceed - but was hoping for feedback before blinding trying.Thanks for your reply.
