The PIC16F1704-I/SL is a 8-Bit 14-pin advanced analogue Flash Microcontroller with extreme low power (XLP). This microcontroller delivers on-chip operational amplifier, core independent peripherals (CLC, COG and zero cross detect) and peripheral pin select, providing for increased design flexibility. 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.
