The PIC16LF747T-I/ML is a low-cost, high-performance 8-bit CMOS microcontroller featuring a fully static architecture with low-power sleep modes. It features a 13-bit instruction length and 216 instructions, including 13 interrupt sources, 7 general purpose registers, 5 timer/counter registers and 8 interrupt registers. It also features an asynchronous, external bus with an internal 16-bit counter/timer, A/D convertor, UART and other peripherals such as EEPOM and EEPROM.

The microcontroller is ideal for applications requiring signal processing, serial communications, A/D conversion, timing and synchronization, and control regulation. It is suitable for applications in appliances, power supplies, industrial instruments and automation, health, communications, security and so on.

The PIC16LF747T-I/ML is available in a 40-pin package, with priority is given to the size and cost of the device. The functionality of the microcontroller is protected by a combination of hardware and software protection, including chip-based hardware encryption. PIC microcontrollers also benefit from unprecedented processing power, allowing for fast execution of control algorithms and an impressive array of peripherals.

The PIC16LF747T-I/ML operates in temperatures ranging from -40°C to +85°C and is designed to operate with a supply voltage range of 2.3 V up to 5.25 V. It also has an operating frequency up to 40 MHz and low-power consumption of around 3 mA/MHz in active mode and 0.1 μA in sleep mode.

The working principle of the PIC16LF747T-I/ML involves an instruction cycle. During the instruction cycle, the processor reads an instruction code from memory. Depending on the instruction code, the requisite operation is performed and the result is stored in a register, or written to the ALU (arithmetic logic unit) or memory. Each instruction cycle is made up of an arithmetic logic unit, an internal register and program counter, address generation unit and a fetch-increment unit. The instruction cycle is repeated until the end of the program.

In addition to the instruction cycle, the PIC16LF747T-I/ML also includes an interrupt processing unit, which can be programmed for either single or multiple interrupts. When enabled, the interrupt unit can be used to respond to external stimulus, or to handle different types of errors such as paper out, memory overrun, and so on. The interrupt processing unit can be enabled or disabled depending on the application.
