The PIC16F1718-I/SP is a 8-bit intelligent analogue Flash Microcontroller combines analogue integration with extreme low power (XLP) to suit a variety of general purpose applications. This microcontroller delivers on-chip operational amplifier, core independent peripherals (CLC, COG, NCO and zero cross detect) and peripheral pin select, providing for increased design flexibility. This family of device contains an enhanced mid-range 8-bit CPU core. The CPU has 49 instructions. Interrupt capability includes automatic context saving. The hardware stack is 16 levels deep and has overflow and underflow reset capability. The microcontroller with direct, indirect and relative addressing modes. Two file select registers (FSRs) provides the ability to read program and data memory.
