STMicroelectronics Pty Ltd introduces a new range of 1.8V microcontrollers designed as specific low-voltage devices that help overcome the challenges faced by designers when adding a companion chip to a low-voltage host processor.

The latest STM32 microcontrollers from STMicroelectronics are focused low-voltage microcontrollers that 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 analogue domain is particularly strong where a wide analogue dynamic range is required, or for connecting directly to USB devices.

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 STM32F0 and STM32F3 series, ensure unparalleled design flexibility and scalability.

The low-voltage product lines allow designers to take advantage of the same features as mainstream STM32F0 and STM32F3 product series with no compromise or degradation in processing performance when operating at the lower voltage.

These two new STM32 series are well suited for use in portable consumer applications such as smartphones, accessories and media devices, and 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.
