SummaryPIC16F170X/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.
