Manchester encoding in low-end SM32s

Are there any low-cost STM32 processors available which support Manchester encoding in the USART or similar?

The Main processor will be a high-end STM32, but I need to bring some data across a "difficult" isolation barrier, and one very easy way to do this would be to have a cheap processor on the "live" side of the barrier, measuring various things and streaming the data, Manchester  encoded. This would mean I could use a low-cost, high spec pulse transformer to get all the data across the isolation barrier, at low power and high speed. For this application I do not need a return channel.
