Product Description:

8051-Z51F6412-DEV is a Microcontroller Board in a series of MCS51 that is a new release from Zilog Inc. In past years, Zilog Inc. has made and developed Microprocessor in a series of Z80 that is popularly widespread. Zilog Inc. has lately developed a new Microcontroller in a series of MCS51 called Z8051. The Z8051 has 8BIT CISC Single Chip Microcontroller that uses the architectural structure for processing data of MCS51 according to the Intel format. However, Zilog has developed and modified all new operational system with I/O Peripheral such as I/O Port, UART and Timer/Counter. In this case, it still controls and access these I/O Peripherals through SFR (Special Function System), similarly to Intel. So, the format of the programming to command the operation is still the same as MCS51 from Intel. Moreover, Zilog also develops and improves the efficiency of Z8051 to be higher standard of the MCS51; such as speed of processing data, increasing unit for mathematical calculation of 32Bit integral multiplication and division, energy management, and adding special I/O Peripherals such as GPIO Port, Pin Pull-Up, Pin Debounce, Pin Change Interrupt, USART, SPI, I2C, ADC, Timer/Counter/Capture/PWM, and Buzzer Control. Furthermore, it can support Interrupt better than the MCS51. As mentioned above, user can write program to command Hardware easily and reduces complex procedures for developing program.
