Circuit principle: This system uses NuMicro M05132-bit microcontroller to realize the interface with IC card. It is responsible for the storage and reading of card clock and data. It reserves the RST, FUS, PGM and other signals required by other types of IC cards. IC card The insertion and dialing are identified by the switch on the IC card adapter socket, and the hardware interface circuit diagram is as shown. The N u M icro M051 series is a 32-bit microcontroller with an ARM C ortex - M 0 core. The Cortex-M0 is ARM's newest 32-bit embedded processor with the price advantage that rivals traditional 8-bit microcontrollers. The NuMicro M051 series includes M052, M054, M058 and M0516. The NuMicro M051 core series can run up to 50MHz, making it ideal for industrial applications requiring high-speed control. The NuMicro M051 series embeds 8K/16K/32K/64K bytes of flash memory, 4kBflash for ISP, and 4kB SRAM. Numerous system-level peripheral functions such as I/O Port, EBI (External Bus Interface), TImer, UART, SPI, I2C, PWM, ADC, Watchdog Timer, and Undervoltage Detection, built into the NuMicro M051 Series Features reduce system peripheral components, save board space and system cost, and these features make the NuMicro M051 Series suitable for a wide range of applications. At the same time, NuMicro M051 has built-in online programming function ISP and system programming function ICP, which provides users with various programming methods. Users can upgrade the chip directly on the board.
