Multi-functional all-in-one machine application solution based on AT32 MCU

In the past, four machines were indispensable for the establishment of business offices, such as copiers, printers, scanners and fax machines. In order to shorten manpower working time and improve work efficiency, various office equipment are gradually introduced to better meet human needs, such as multi-function all-in-one machines. It is also one of the major changes. An all-in-one machine mainly integrates machines for different purposes such as printing, copying, scanning, and faxing into one machine, and combines it with networking functions . As devices have more functions, the risk of information security and privacy leakage increases. As a programmable integrated circuit chip, a microcontroller has processing and control functions, can execute complex instruction sets, and manages communication and collaborative work between functional modules. , to ensure the efficient, stable and safe operation of the entire system.

AT32F435/F437 series of high-performance MCUs have efficient data processing capabilities. They use ARM® Cortex®-M4 as the core, have a maximum frequency of 288MHz, support up to 4032KB Flash and up to 512KB SRAM, and have built-in FPU, DSP and various complex peripherals. Designed for customers to use flexibly, such as dual QSPI, dual OTG, DVP and multiple communication interfaces, XMC supports memory expansion such as SDRAM, SRAM, PSRAM, etc. In addition, it also provides 3 sets of high-speed (5.33Msps) ADC independent engines, which can handle complex Printing, scanning, copying and faxing tasks, fast response time and efficient algorithms enable the all-in-one machine to complete various operations in a short time.

Application features of AT32F435/437 in multi-function all-in-one computers:

1. High-performance CPU clock speed provides a configurable hardware pipeline to support printing, scanning, copying, and faxing functions.

2. Supports multiple sets of high-speed PWM outputs and can handle multiple motor controls at the same time.

3. Multi-channel ADC/DAC supports multiple sets of sensors for precise sensing and printing control.

4. Up to 18 timers meet the highly integrated motion control of the printing unit control output, thereby reducing the overall system cost and complexity.

5. The circuit board is miniaturized, with built-in high-speed on-chip oscillator and small-size packaging.

6. Import the sLib Security Library to support password protection of the specified range of program areas to ensure high chip security.

7. Integrate key high-speed communication interfaces, such as USART/UART, USB OTG, CAN, SDIO, Ethernet (only supported by AT32F437 series), etc., to improve the efficiency and stability of the networking system.

8. Support chip software OTA upgrade, which facilitates the update, improvement and expansion of multi-functional all-in-one machines.
