Working Principle

The PIC17C42AT-33I/PT microcontroller is based on the Harvard architecture, which separates program and data memories. It also has a 16-bit wide instruction word, allowing it to handle more instructions per cycle as compared to traditional 8-bit controllers. The single cycle instruction execution time for this device is 33nS.

The device is programmed using the ICSP (In-Circuit Serial Programming) protocol, which is an industry standard method. It is also hardware compatible with the Microchip PIC10F204/206, PIC12F508/508A, PIC16F505/505A, PIC16F506/506A, and other processors. To facilitate code development, the code size can be up to 8K words with code protection, shadow program/data memory, software breakpoints, and serial in-system programming.

The PIC17C42AT-33I/PT provides a Sleep mode which reduces power consumption to as little as 0.1uA. The device also features a Hardware Wake-up facility, allowing the user to wake up the controller from a low power state with a low voltage periphery. The low voltage peripheral can trigger an interrupt or reset the controller from its power saving sleep state.

The PIC17C42AT-33I/PT is also capable of multiple clock sources. Its oscillator block supports precision crystal oscillators, ceramic resonators and RC oscillators. It also provides 1 MIPS/MHz operation from a 4MHz crystal, which allows it to be used in real-time embedded applications.
