1.8 V, 32-bit MCUs have separate analog domain

The STM32F078 and STM32F378 low-voltage microcontrollers are intended for use as companion devices to low-voltage host processors. As such they can enable flexible design partitioning. They feature a 1.8 V digital supply with an independent analog domain.

STM32F078 devices have a Cortex-M0 core and up to 128 Kbytes of flash, while the STM32F378 has a Cortex-M4 core with a floating-point unit and up to 512 Kbytes of flash. The ICs have an A/D converter, touch sensing and 5V-tolerant I/Os, a 96-bit unique ID, and SPI, I2S, USART, I²C, and CAN ports.
