AT32F403A Series Datasheet:ARM®-based 32-bit Cortex®-M4F MCU+FPU with 256 to 1024 KB Flash, sLib, USB, 17 timers, 3 ADCs, 20 communication interfaces
Introduction：
This datasheet provides the ordering information and mechanical device characteristics of the AT32F403A microcontrollers.The AT32F403A datasheet should be read in conjunctionwith the AT32F403A reference manual.For information on programming, erasing, and protection of the internal Flash memory please also refer to the AT32F403A reference manual.For information on the Cortex®-M4core please refer to the Cortex®-M4Technical Reference Manual
Description：
The AT32F403Aincorporates the high-performance ARM®Cortex®-M4F 32-bit RISCcore operating at 240MHz. The Cortex®-M4Fcore features a Floating point unit (FPU)single precision which supports all ARM single-precision data processing instructions and data type. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.The AT32F403Aincorporateshigh-speed embedded memories (up to 1024 KBytes of Flash memory, 96+128 KBytes of SRAM), the extensive external SPI Flash (up to 16 Mbytes addressing capability), and enhanced I/Os and peripherals connected to two APB buses.Any block of the embedded Flash memory can be protected by the sLib, functioning as a security area with code-excutable only.The AT32F403Aoffers three 12-bit ADC, two 12-bit DAC, eight general-purpose 16-bit timers plus two general-purpose 32-bit timers, and up to twoPWM timers for motor control, as well as standard and advanced communication interfaces, up to three I2Cs, four SPIs (all multiplexed as I2Ss), two SDIOs, eightUSARTs, an USB, and twoCANs.The AT32F403Aoperates in the -40 to +105 °Ctemperature range, from a 2.6 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power application.
