About

Performance and energy savings

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 35 µA/CoreMark® score. The S6E1C-Series consumes only 40 µA/MHz in the active mode.

Ultra-low power

The devices in the ultra-low-power group have an operating voltage range of 1.65 V to 3.6 V, a maximum CPU clock frequency of 40 MHz, an active-mode current of 40 μA/MHz, and an RTC standby-mode current of 0.6 μA. The devices also feature a segment LCD controller and a set of analog peripherals. The products are available with pin counts ranging from 30 to 64.

High performance flash

Memory densities range from 64 KB to 128 KB flash and up to 16 KB RAM, typically found only in MCUs with larger Cortex®-M3/M4 cores. The flash features a true zero-wait-state operation at full CPU speed and data retention of up to 20 years.

Other major features

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 USB 2.0 host and device capabilities and also offer multiple serial communication interfaces and AES encryption.
