Build with AT32F415 — Datasheet Specs & AI Design Help

00 — Overview

What the AT32F415 does

The AT32F415xx family are 32-bit ARM Cortex-M4 microcontrollers featuring 64 to 256 Kbytes of flash, 32 Kbytes of SRAM, and up to 55 GPIO ports. These devices operate at frequencies up to 150 MHz with a 12-bit 2 MSPS ADC, 11 timers, and 12 communication interfaces including CAN and OTGFS. Available in LQFP64, LQFP48, QFN48, and QFN32 packages, they support operating temperatures from -40 to +105 °C. Engineers typically use these MCUs for embedded control applications requiring high performance, flexible peripherals, and robust power management features across commercial, industrial, and military temperature grades.
