Wakeup current peaks can be reduced to industry’s lowest values leading to savings in terms of decoupling capacitors on the supply line and an ultra-low-power oscillator achieves 87µA/MHz in run mode
The microcontroller also offers a wide range of functionalities, such as an LCD interface, comparator, DAC and hardware encryption.
The load on the ARM Cortex-M0+ core has been reduced by new autonomous peripherals (including USART, I²C, touch sense controller), leading to fewer CPU wakeups and contributing to decreased processing time and power consumption.
Other value-added features such as 16-bit ADC (HW oversampling), crystal-less USB, short wake-up time and communication peripherals capable of operating in ultra-low-power mode make up for an unrivalled balance of feature integration, performance and ultra-low-energy consumption.
The microcontroller is available with up to 64 Kbytes of Flash, 8 Kbytes of RAM and up to 2 Kbytes of embedded EEPROM (no emulation needed) in 32- to 64-pin packages, including a space-saving WLCSP36
