Design ultra-low-power IoT system with industry's most energy-efficient Arm® Cortex®-M0+ MCUs
FM0+ 32-bit Arm® Cortex®-M0+ Microcontroller (MCU) Families subcategories
The FM0+ portfolio of Flexible Microcontrollers are the industry's most energy-efficient 32-bit Arm ® Cortex®-M0+ based MCUs. This portfolio of MCUs is designed for ultra-low-power and cost-sensitive applications such as white goods, sensors, meters, HMI systems, power tools and Internet of Things (IoT) battery-powered or wearable devices. These microcontrollers can be easily embedded into systems adopting 8-, 16- or 32-bit MCUs, accelerating product development and reducing development costs.
The MCUs are based on the Arm® Cortex®-M0+ core, the most energy-efficient Arm processor available today. The optimized processing and flash architecture of the FM0+ family make it the industry's most energy-efficient Cortex-M0+ MCUs, achieving an industry-leading 35µA/CoreMark® score. The S6E1C-Series consumes only 40µA/MHz in Active mode, where the S6E1B-Series feature an ultra-low-power 0.6µA Standby mode.
The devices in the ultra-low-power group have an operating voltage range of 1.65V to 3.6V, and a maximum CPU clock frequency of 40MHz, Active mode current of 40μA/MHz and an RTC standby mode current of 0.6μA. The devices also feature a segment LCD controller and set of analog peripherals. The products are available with pin counts ranging from 32 to 120.
Memory densities range from 56 KB to 560 KB Flash and up to 64 KB RAM - typically found only in MCUs with larger Cortex-M3/M4 cores. The flash memory features a true zero-wait-state operation at full CPU speed and data retention of up to 20 years.
A simplified bus matrix reduces power consumption. The devices also include local clock gating for each peripheral, a separated clock divider for the CPU and peripherals, low pin counts, and low memory density. The FM0+ MCUs feature Full-Speed USB2.0 Host and device capabilities, and also offer multiple serial communication interfaces and AES encryption.
