The device integrates an 11-channel 10-bit ADC, two analog comparators with SR latch mode, one standard CCP and one Enhanced CCP module with auto-shutdown and PWM steering, an EUSART supporting RS-485\/RS-232\/LIN, and an MSSP module supporting both SPI and I2C with address mask. The 8MHz internal oscillator is factory-calibrated to +\/-1% with software tuning, and features two-speed start-up and fail-safe clock monitoring. The Ultra Low-Power Wake-up (ULPWU) pin enables battery-powered applications.","working_principle":"The PIC16F882-I\/SO operates as an 8-bit PIC16 mid-range microcontroller. (1) The CPU executes 35 single-word instructions through a 2-stage pipeline at up to 5 MIPS (20MHz). The 8-level hardware stack supports subroutine nesting and interrupt handling. (2) The Enhanced CCP module provides auto-shutdown capability that immediately disables PWM outputs when a fault condition is detected, and PWM steering allows redirecting PWM output to alternative pins without CPU intervention. (3) The ULPWU pin uses an internal weak pull-up connected to an external capacitor; when the capacitor discharges below the logic threshold, it generates a wake-up interrupt, enabling periodic wake-up from sleep with minimal power consumption. The fixed 0.6V internal voltage reference allows monitoring VDD without external components by comparing against the ADC reading.","pin_description":"
