Summary
PIC16F170X/171X microcontrollers (MCUs) combine Intelligent Analog integration with low cost and eXtreme Low Power (XLP) to suit a variety of cost-sensitive general-purpose applications. These devices deliver on-chip Analog features (op amps, ADC and DAC) along with other Core Independent Peripherals (CIP) in 14, 20, 28 and 40 pin packages. PIC16F170X/171X MCUs also feature Peripheral Pin Select (PPS) and Zero Cross Detect, to provide increased design flexibility.

KEY FEATUREs
■ Intelligent Analog: Integrates up to two op amps, up to
   two high speed comparators, up to 28 input channels
   of 10-bit ADC and up to one 5-bit/8-bit DAC, saving both
   board space and design BOM costs.
■ Confi gurable Logic Cell (CLC): Create custom
   combinational and sequential logic using this integrated
   confi gurable logic cell module. Using CLC, designers
   can also bring external gates and state functions into
   the MCU itself.
■ Numerically Controlled Oscillator (NCO): Linearly
   adjusts the frequency output with very fi ne steps. The
   NCO provides high-resolution oscillator capabilities to
   control applications such as lighting ballast, radio and
   tone generator.
■ Complementary Output Generator (COG): Provides a
   complementary waveform with rising and falling edge
   dead band control, enabling high effi ciency synchronous
   switching with no processor overhead. The COG also
   incorporates auto shutdown and auto restart, and can
   directly interface with other peripherals/external inputs.
   It also incorporates blanking and phase control.
■ Zero Cross Detect (ZCD): AC high-voltage zero
   crossing detection for simplifying TRIAC control,
   synchronized switching control and timing.
■ Peripheral Pin Select (PPS): Confi gure any digital
   peripheral to any pin via an internal MUX to ensure
   layout fl exibility and completely eliminate pin overlap.
