FM3 CY9AFx1xK-Series Low Power 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 Infineon 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 CY9AFx1xK-Series is a general purpose family that delivers up to 40 MHz CPU speed, 128 KB flash, 16 KB SRAM and a rich set of peripherals like timers, ADCs, DACs and communication interfaces.
