The PIC16F818-I/SO is an 8-bit microcontroller featuring 1.75KB of Flash program memory, 128 bytes of SRAM, and 128 bytes of EEPROM. It operates within a voltage range of 2.0V to 5.5V and supports low-power modes, making it suitable for battery-operated applications. The device includes 16 I/O pins with individual direction control and supports various oscillator configurations, including internal and external options up to 20 MHz. Key features include a 10-bit, 5-channel Analog-to-Digital Converter (ADC), multiple timers (Timer0, Timer1, and Timer2), and a Capture/Compare/PWM (CCP) module. The microcontroller also supports In-Circuit Serial Programming (ICSP) and In-Circuit Debugging (ICD) via dedicated pins. With a typical EEPROM data retention of over 40 years and a high endurance of 100,000 erase/write cycles for Flash memory, the PIC16F818-I/SO is designed for reliable long-term use in embedded applications.
