Spansion FM4 Family of 32-bit ARM Core Microcontrollers

The FM4 family of 32-bit, general-purpose MCUs covers the highest end of the product range. Based on the ARM® Cortex™-M4F processor core, the family features DSP and Floating Point Unit (FPU) functions.

These MCUs are designed for applications that require advanced, high-speed computing performance such as general-purpose inverters, servomotors, factory automation, PLCs and other industrial equipment, as well as medical and surveillance products, and inverter-based home appliances such as washing machines and air conditioners.

FM4 Family Overview

The FM4 family of 32-bit, general-purpose MCUs covers the highest end of the product range. Based on the ARM® Cortex™-M4F processor core, the family features DSP and Floating Point Unit (FPU) functions.

These MCUs are designed for applications that require advanced, high-speed computing performance such as general-purpose inverters, servomotors, factory automation, PLCs and other industrial equipment, as well as medical and surveillance products, and inverter-based home appliances such as washing machines and air conditioners.

 

Outstanding Performance

The FM4 family operates at clock frequencies of up to 200MHz, and supports an operating voltage range of 2.7V to 5.5V. The devices incorporate 256KB to 2MB Flash and up to 256KB RAM. A fast Flash memory combined with a pre-fetch buffer provides zero-wait-state operation at 200MHz.                   

Functional Safety

The internal, trimmed RC oscillators function as an independent clock source for the clock supervisor and watchdog modules. The devices also feature a two-stage programmable Low Voltage Detector (LVD), a CRC hardware module, a Memory Protection Unit (MPU), and programmable emergency stop input for Pulse Width Modulation (PWM) motor control.

High-Performance Flash Memory

Memory densities range from 256KB to 2MB Flash, with up to 256KB RAM. The high-speed, embedded Flash memory features a true zero-wait-state operation at 72MHz. The secure Flash memory has an endurance of 100,000 write/erase cycles with up to 20 years of data retention. Many devices feature dual-operation Flash for EEPROM emulation.

Low Power Consumption

The devices operate at 0.4mA/MHz, 1.5µA in RTC mode. The dedicated, low-power chip design includes clock and power gating. There are multiple low-power options for finely grained power-saving modes, and a dedicated power domain for deep standby modes.

Advanced Peripherals

The devices include support for Ethernet, Controller Area Network (CAN) and USB2.0. Motor-control features include up to three multifunction timers and respective number of quadrature decoder units. The MCUs include up to three high-speed, 12-bit A/D converters, which can be triggered synchronously and have a conversion time of 0.5µs. Other features include HMI input devices, universal base timers, a sub-clock option, and flexible, multi-function serial interfaces.
