Printer and scanner

Compared with impact and pen printers, thermal printers are characterized by a series of features such as simple structure, small size, light weight, low noise, low power consumption, high printing quality, low price, low operating cost and reliability. It is widely used in hospitals, banks, restaurants, railways, etc. The MM32F3270 series is a general-purpose microcontroller based on the 32-bit Cortex-M3 core.

Clock security mechanism, multi-level power management, general-purpose DMA controller, etc. are integrated on the chip. The main frequency of the system can reach 120MHZ. Its higher processing speed can meet various operation requirements of the printer, and it can be used to develop various printer products.

-GPIO external interrupt supports “Out of Paper” detection and keystroke detection

- High-speed SPI port is convenient for plug-in SPI FLASH to store fonts

- USB OTG function supports USB connection and U disk, etc.

- 12-bit ADC port of high precision supports over-temperature detection and motor control detection.
