Spansion FM3 Family of 32-bit ARM Core Microcontrollers

The FM3 family of 32-bit general-purpose MCUs is based on the ARM® Cortex™-M3 CPU. The family is split into four groups: high-performance, basic, low-power and ultra-low-leakage. All these products are based on the same architecture for software compatibility, use the same peripherals, and are pin compatible in most cases. The main differences between the groups are the CPU operating frequency and the supply voltage.

FM3 Family Overview

The FM3 family of 32-bit general-purpose MCUs is based on the ARM® Cortex™-M3 CPU. The family is split into four groups: high-performance, basic, low-power and ultra-low-leakage. All these products are based on the same architecture for software compatibility, use the same peripherals, and are pin compatible in most cases. The main differences between the groups are the CPU operating frequency and the supply voltage.

              
 

High Performance

The FM3 family operates at high clock frequencies of up to 144MHz. The wide operating voltage range (1.65V to 5.5V) is unique among Cortex-M3 microcontroller families. This family serves both low-power applications and robust industrial designs, which require an increased signal-to-noise ratio. The devices, which incorporate up to 1.5MB Flash and 192KB RAM, feature a pre-fetch buffer for zero-wait-state operation at 144MHz.

Advanced Peripherals

Peripheral features include multiple motor-control timers, high-speed ADCs, and a variety of communication interfaces. Available packages, which range from 32 to 176 pins, include LQFP, QFN and BGA types.

High-Performance Group

The high-performance group, which operates at up to 144MHz, has an operating voltage range of 2.7 to 5.5V, and incorporates up to 1MB Flash with 128K RAM with extra Flash memory for EEPROM emulation. Peripherals include support for Controller Area Network (CAN), Ethernet and USB. Typical applications include factory automation, home automation, motor control and medical applications.

Basic Group

The basic group operates at up to 72MHz, with an operating voltage range of 2.7V to 5.5V. The devices, which are available in 32- to 176-pin packages, incorporate 64KB to 1.5MB Flash and up to 192KB RAM. The group supports peripherals such as CAN, USB2.0, and motor control. Typical applications include household appliances, office automation, power tools and factory-automation sensors.

Low-power Group

The low-power group operates at up to 40MHz, with an operating voltage range of 1.65V to 3.6V. Separate power domains, low-power current (typically 200μA/MHz), and support for USB2.0, LCDC, and HDMI-CEC help make these MCUs appropriate for applications such as handheld devices, metering systems, medical devices, and battery-powered applications.

Ultra Low-Leakage Group

The ultra-low-leakage group has a frequency of up to 20MHz, an operating voltage range of 1.8V to 5.5V, and a low leakage current of ~0.4μA (at DS-Stop mode). The devices, which incorporate an optimized, low-leakage process technology, support LCDC and HDMI-CEC. Typical applications include metering systems, mobile devices, and handheld devices.
