The working principle of UPD78F1145AF1-AN1-A is that when the device is powered up, the microcomputer\'s program counter is reset to 0. The program counter then reads the instructions from the memory and sets the instruction pointer to the address of the instruction. The instruction pointer reads the instruction and the control unit translates the instruction value into control words and generates signals required for this instruction. The instruction is then sent to the arithmetic logic unit, where it is executed. The result of the execution is sent to the memory and the program counter is incremented to the next instruction.

In summary, the UPD78F1145AF1-AN1-A is an 8-bit microcontroller developed by Renesas Electronics based on the M78F1045A core. It has a wide range of applications in various industries and its main usage are in automatic control and household applications. The working principle is that when the device is powered up, the control unit translates the instruction value into control words and generates signals required for its execution. The result of the execution is sent to the memory and the program counter is incremented to the next instruction.
