It combines eXtreme Low-Power (XLP) technology with an integrated LCD charge pump and bias generator supporting up to 360 LCD segments. The 12-bit ADC2 automates Capacitive Voltage Divider (CVD) techniques for advanced touch sensing with built-in averaging, filtering, oversampling, and automatic threshold comparison. The device features 56KB Flash, 4KB RAM, and 256B EEPROM for ample program and data storage. The 59 I\/O pins with Peripheral Pin Select (PPS) provide flexible peripheral routing. Core Independent Peripherals (CIPs) including 4 CLC modules, CWG, and 10-bit PWM enable hardware-based control loops without CPU intervention. The high-precision internal oscillator with active clock tuning over voltage and temperature eliminates the need for external crystals in many applications.","working_principle":"The PIC16F19197-I\/PT operates as an 8-bit PIC microcontroller with extensive mixed-signal peripherals. (1) PIC16 Core: The enhanced mid-range 8-bit core executes instructions at up to 32MHz with single-cycle execution for most instructions (4 clock cycles per instruction). The hardware multiply and 16-bit index registers improve computational throughput. (2) LCD Controller: The integrated LCD module drives up to 360 segments using a charge pump that maintains contrast across the supply voltage range. The bias generator produces the required LCD bias voltages internally. (3) ADC2 with CVD: The 12-bit ADC2 implements Capacitive Voltage Divider touch sensing by automatically alternating the charge\/discharge cycle on the touch pins and computing the difference, eliminating the need for external touch controller ICs. (4) CLC: Four Configurable Logic Cells implement combinational and sequential logic functions in hardware, offloading the CPU from simple logic operations. (5) XLP: The eXtreme Low-Power modes (Sleep, Idle, Doze) reduce current consumption to nanoamp range while maintaining RTCC and LCD operation.","pin_description":"
