FM3 CY9BFx2xK/L/M-Series Arm® Cortex®-M3 Microcontroller (MCU) Family

Overview

Arm® Cortex®-M3 based general purpose MCU, with low power modes, integrated Flash memory, SRAM, and rich peripheral functions.

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. As a part of the Infineon FM3 family of Arm® Cortex®​-M3 based microcontrollers, the CY9BFx2xK/L/M-Series is a general purpose family with low power modes, integrated flash memory, SRAM, and rich peripheral functions like timers, ADCs, DACs, and communication interfaces.
