Microchip PIC16F818-I/SO 8-bit PIC Microcontroller 20 MHz, 1.792 kB Flash, 128 B RAM, 18-Pin SOIC

Microchip PIC16F818-I/SO is an 8-bit PIC microcontroller featuring the PIC16F series architecture. It runs at a maximum clock frequency of 20 MHz and has a program memory of 1.792 kB flash, accompanied by 128 bytes of RAM. The 18-pin SOIC surface-mount package optimizes board space while enabling flexible application integration.

This microcontroller supports a 5-channel 10-bit analog-to-digital converter (ADC), allowing the conversion of analog signals to digital data across multiple inputs. It contains three timers, comprising two 8-bit timers and one 16-bit timer, thereby facilitating various timing and counting functions essential in embedded systems.

Additional peripherals include a capture/compare/PWM (CCP) module and a synchronous serial port (SSP) capable of SPI and I2C communications, making it adaptable for complex control and communication tasks. The device architecture is based on Microchip's Mid-Range 8-bit PIC core with 35 instruction sets and an 8-level hardware stack, delivering up to 5 MIPS throughput for efficient processing.

Operating voltage ranges from 2 V to 6 V with a maximum power dissipation of 800 mW. The microcontroller operates reliably in temperature conditions from -40°C to +85°C. Built-in power management features include Power-On Reset (POR), Brown-Out Reset (BOR), Power-Up Timer (PWRT), Oscillator Start-Up Timer (OST), and a Watchdog Timer (WDT) to enhance system stability and robustness. In-circuit programming and debugging are supported through ICSP and ICD interfaces.

This microcontroller is suitable for industrial, commercial, and consumer electronic applications requiring compact, reliable control solutions. Its versatile peripheral set and compact SOIC form factor make it ideal for embedded systems design, automation, instrumentation, and communication interfaces.
