STC8H8K64U-45I-SOP16 1T 8051 Microprocessor Microcontroller Chip 

STC8H series microcontrollers are microcontrollers that do not require an external crystal and external reset, and they are 8051 microcontrollers aiming at super anti-interference/ultra-low price/high-speed/low-power consumption. At the same operating frequency, STC8H series microcontrollers are about 12 times faster than traditional 8051 (11.2~13.2 times faster). 11.2~13.2 times faster than conventional 8051), to execute all 111 instructions in sequence, STC8H series microcontroller only needs 147 clocks, while conventional 8051 needs 1944 clocks. STC8H series microcontroller is STC's single-clock/machine-cycle (1T) microcontroller, and it is the new-generation 8051 microcontroller which is wide-voltage/high-speed/high-reliable/low-power/strong anti-static/stronger anti-jamming, and the new-generation 8051 microcontroller which is super high speed/low power targeting at the same working frequency. It is a new generation 8051 microcontroller with super encryption. The instruction code is fully compatible with the traditional 8051. 

MCU integrates a high precision R/C clock internally, and the operating frequency can be set during ISP programming, which completely eliminates the need for expensive external crystals and external reset circuits, and there are three optional clock sources inside the MCU, an internal high-precision IRC clock (which can be appropriately adjusted up or down), an internal 32KHz low-speed IRC, and an external 4M~33M crystal or an external clock signal. signal. The clock source can be freely selected in the user code, and after the clock source is selected, it can be divided by an 8-bit frequency divider and then provide the clock signal to the CPU and each peripheral.

The MCU provides rich digital peripherals (serial port, timer, advanced PWM, I2C, SPI, USB) and analog peripherals (ultra-high-speed ADC, comparator) to meet the design needs of a wide range of users.

The STC8H series microcontrollers integrate an enhanced dual data pointer. The automatic increment or decrement function of the data pointer and the automatic switching function of the two sets of data pointers can be realized through program control.
