ST STM32L476QGI6

ARM® Cortex®-M480MHz1MB（1M x 8）

Overview

The STM32L476/STM32L486 devices extend the ultra-low-power portfolio and performance with an ARM® Cortex®-M4 core with DSP and Floating-Point Unit (FPU) at 80MHz. This series offers USB OTG 2.0 full speed, a Liquid Crystal Display (LCD) driver in addition to the significant set of peripherals.Advanced Encryption Standard (AES) 128-/256-bit hardware encryption is available on STM32L486 devices.
