FM3 CY9BFx1xS/T-Series Arm® Cortex®-M3 Microcontroller (MCU) Family

Overview

Arm® Cortex®-M3 Based MCU, dedicated embedded controlers with high-performance and competitive cost

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 CY9BFx1xS/T-Series is a high performance group that operates with a voltage range of 2.7V to 5.5V. The FM3 CY9BFx1xS/T-Series delivers high-performance with a 144 MHz CPU clock speed, 1 MB of flash with 16 KB pre-fetch buffer for zero-wait-state operation at 144 MHz.
