Controller recommendation for migrating from to now available controller

[firoz3321]

Hi We have a product in market which uses UPSD3234  controller.

Can someone please suggest a controller that can be used to replace this with minimal code changes that supports

1. USB2.0 or above and
2. has more than one UART
3. Ethernet (optional)

Thank you.

This will be almost impossible due to your requirement of "minimal code changes": the UPSD3234 was a 8032 based MCU, which is completely different from the microcontrollers currently provided by STMicroelectronics (STM8/STM32/etc).

Of course you can start a new project that has the same behavior as the one with the UPSD3234, but an STM8 does not offer any USB functionality. You should therefore select a device from the STM32 family, e.g. the STM32F407.

Good luck!

Thank you. We will look into the STM32 series.
