ST STM32F427VIT6

ARM® Cortex®-M4180MHz2MB（2M x 8）

Overview

The STM32F427xx and STM32F429xx devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm® singleprecision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. 

Applications • Motor drive and application control • Medical equipment • Industrial applications: PLC, inverters, circuit breakers • Printers, and scanners • Alarm systems, video intercom, and HVAC • Home audio appliances
