Spansion 32-bit ARM Core MCUs

Spansion’s FM MCU microcontroller family, which is based on the ARM® Cortex™-M4, M3, M0+ and R4 CPUs, is a scalable platform for many industrial applications. Customers can select the most appropriate device from a range of products, coming in packages from 32 to 216 pins, with Flash memory densities between 56KB and 2MB.

FM4

FM4 Family

The FM4 family of 32-bit, general-purpose MCUs is based on the ARM Cortex-M4F processor core. This family, which features DSP and Floating Point Unit (FPU) functions, covers the highest end of the product range. The MCUs are designed for applications that require advanced, high-speed computing performance such as general-purpose inverters, servomotors, PLCs and other industrial equipment, as well as inverter-based home appliances such as washing machines and air conditioners.

High-level FM 4 Features
  • ARM Cortex-M4F series core
  • Frequency: up to 200MHz
  • Operating voltage: 2.7V-5.5V
  • Low power consumption: 0.4mA/MHz, 1.5µA RTC mode
  • Up to 2MB Flash, 256KB RAM
  • CAN, Ethernet, USB

FM3

FM3 Family

The FM3 family of 32-bit general-purpose MCUs is based on the ARM Cortex-M3 CPU, which provides a scalable platform for many consumer and industrial applications. Popular applications range from motor control, factory automation, white goods and power tools to medical devices, major home appliances, digital consumer devices and office automation equipment. The FM3 family, which features a maximum operating frequency of 20 to 144 MHz, is split into four groups: high-performance, basic, low-power and ultra-low-leakage.

High-level FM 3 Features
  • ARM Cortex-M3 series core
  • Frequency: up to 144MHz
  • Operating voltage: 1.65V-5.5V
  • Up to 1.5MB Flash, 192K RAM
  • CAN, Ethernet and USB
  • Segment LCDC

FM0+

FM0+ Family

The FM0+ family, which is based on the ARM Cortex-M0+ core, is designed for industrial and cost-sensitive applications with low power requirements such as white goods, sensors, meters, Human Machine Interface (HMI) systems and power tools. The devices can be easily embedded into systems adopting Spansion’s 8-, 16- or 32-bit MCUs, accelerating product development and reducing development costs. The family includes ultra-low-power and entry-level groups.

High-level FM0+ Features
  • ARM Cortex-M0+ series core
  • Frequency: 40MHz
  • Operating voltage: 1.65V-3.6V (ultra-low-power group) and 2.7V-5.5V (entry level group)
  • Low power consumption
  • Cost efficiency

FCR4

FM4 Family

The FCR4 family has been especially designed to offer an innovative, scalable solution for hybrid instrument clusters, which combine traditional meters and graphical displays. The devices offer a powerful architecture based on the ARM Cortex-R4 core and Spansion’s 2D “Iris” graphics engine.

High-level FCR4 Features
  • ARM Cortex-R4 core
  • Embedded 2D “Iris” graphics engine
  • 2MB Flash, 64KB E2Flash
  • Up to 208KB RAM
  • Cluster features including real-time clock/auto calibration, sound generator and I2S
