Spansion FM0+ Family of 32-bit ARM Cortex Microcontrollers

The FM0+ family of Flexible Microcontrollers are the industry's most energy-efficient 32-bit ARM® Cortex®-M0+ based MCUs. This family 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 FM0+ family includes three product series for ultra-low-power and cost-effective applications:

FM0+ S6E1A-Series: A 40MHz ARM® Cortex®-M0+ MCU, featuring up to 88KB Flash and robust 2.7 - 5.5V operating voltage range for industrial applications

FM0+ S6E1B-Series: A 40MHz ARM® Cortex®-M0+ MCU, featuring up to 560KB Flash and 102 GPIO - the industry's largest memory and IO footprint for a Cortex®-M0+ based microcontroller, for secure and reliable M2M communications with AES encryption

FM0+ S6E1C-Series: A 40MHz ARM® Cortex®-M0+ MCU, featuring up to 128KB Flash and 54 GPIO - with an industry-leading 35µA/CoreMark® score for ultra-low-power applications

The FM0+ families also include Connect USB, a complete solution to generate USB ready template projects for USB Device and Host applications.

FM solutions include:
Touch for capacitive touch inputs (buttons, sliders, scroll wheels, X/Y pads)
Connect USB a complete solution to generate USB ready template projects for USB Device and Host

FM0+ Family Overview

The FM0+ family of Flexible Microcontrollers are the industry's most energy-efficient 32-bit ARM® Cortex®-M0+ based MCUs. This family 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.

 

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 35µA/CoreMark® score. The S6E1C-Series consumes only 40µA/MHz in Active mode, wheres the S6E1B-Series feature an ultra-low-power 0.6µA Standby mode.

 

High-Performance Flash Memory

Memory densities range from 56KB to 560KB Flash and up to 64KB 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.

 

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 USB2.0 Host and Device capabilities, and also offer multiple serial communication interfaces and AES encryption.

 

Ultra-Low-Power Group

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 80 to 120.
