MG82F6D17AT2 - 8051 Core MCU - 12bit - 36MHz - 16KB Flash - 1KB SRAM - Microcontroller IC - TSSOP-20
MG82F6D17 is a single-chip microprocessor with a high-efficiency 1-T structure based on 80C51. Each instruction requires 1 to 7 clock signals (6 to 7 times faster than the standard 8051), which is the same as the standard 80C51. Quasi-8051 instruction set compatible. Therefore, with the same processing power as the standard 8051, the MG82F6D17 only needs a very low operating speed, and thus Can greatly reduce power consumption.
MG82F6D17 has 16K bytes of built-in Flash memory for saving codes. Flash memory can be programmed in serial mode (ICP, in-circuit programming) or The ability to program in ISP mode. At the same time, in-application programming (IAP) capabilities are also provided. ISP and ICP allow users to operate the microcontroller without removing the microcontroller from the product Download new code; IAP means that the microcontroller can write non-volatile data in Flash while the application is running. These functions are controlled by the built-in charge pump Providing high voltage for programming does not require an external high voltage supply.
MG82F6D17 has multiple working modes to reduce power consumption: idle mode, power-down mode, slow frequency mode, sub-frequency mode, RTC mode, watch mode and monitor mode. In idle mode, the CPU is frozen while peripheral modules and the interrupt system are still active. In power-down mode, random access memory RAM and special functions The value of register SFR is saved and all other functions are terminated. Most importantly, a microcontroller in power-down mode can be woken up by a variety of interrupts or resets. exist In slow frequency mode, users can slow down the system speed through the 8-bit system clock divider to reduce power consumption. Select sub-frequency mode.
The system clock comes from the internal low-speed oscillator. The processor CPU is running at a particularly slow speed. Real-time clock (RTC) mode supports real-time clock function in all modes, watch mode, power-down mode or In idle mode, WDT overflow acts as an automatic timer to wake up the CPU. Monitor mode, monitors the voltage in power-down mode, and resets when the voltage is particularly low.
