ST trims STM32 for 1.8V operation

“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,” said the supplier.

The ADC peripheral of STM32F3x8 devices is fully functional down to 1.8V

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 F3 series.

They are offered in low-profile CSP, UQFN or UFBGA package styles as well as TSSOP and LQFP. The full range of package options spans configurations from 20 pins to 100 pins.
