AT32F407 series microcontrollers, based on 32-bit ARM® Cortex®-M4
core, utilize advanced process to achieve 240 MHz computing speed. The embedded single
precision floating-point unit (FPU) and digital signal processor (DSP), various
peripherals and flexible clock control mechanism can meet a wide range of applications.
It also features up to 1 MB Flash memory, 224 KB SRAM and Flash access zero wait, far
beyond the same level of chip industry.
In addition, AT32F407 series also imports the Security Library to support the use of
passwords to protect the specified program area, in which IDH programs the core
algorithm and provides to downstream customers for secondary development. Moreover,
there are eight sets of UART serial interfaces, two sets of CAN buses and compatible
IEEE-802.3 10/100 Mbps Ethernet port controllers available to suit for IoT applications.
The USB device applications, without the need of external crystal oscillators, can
reduce costs while enhancing the reliability of end products.
AT32F407 devices not only perform well in the temperature range of -40 to 105°C , but
also offer a variety of chips for selection in response to diverse memory requirements.
Through its powerful on-chip resource allocation, high integration and cost-effective
performance, they are able to maintain its competitive edge in terms of design solutions
with high computing demands.
