1.8V STM32 Microcontrollers for designs interfacing with low voltage host

The latest STM32 microcontrollers from STMicroelectronics are specific low-voltage devices that help overcome the challenges designers face when adding a companion chip to a low-voltage host processor. These focused low-voltage microcontrollers connect to the same digital power domain as the host, such as a 1.8V power supply, while allowing on-chip peripherals to operate from higher voltages such as 3.3V, giving freedom from the usual performance trade-offs that come with lower supply voltages. The STM32F038/48/58/78 and STM32F318/28/58/78 are ideal low-voltage companion microcontrollers that enable flexible design partitioning. The combination of 1.8V digital supply voltage and independent analog domain is particularly strong where a wide analog dynamic range is required, or for connecting directly to USB devices. STM32F0x8 I/Os allow bridging between different voltages without using level shifters The ADC peripheral of STM32F3x8 devices is fully functional down to 1.8V Versatile processing and memory configurations are available. STM32F0x8 devices combine the ARM Cortex-M0 core with up to 128Kbyte on-chip Flash, while the STM32F3x8 based on the ARM Cortex-M4 core with DSP instruction set and floating-point unit have up to 512Kbyte. Extensive pin, peripheral, and software compatibility between the two new low-voltage families, and with the mainstream STM32 F0 and STM32...
