PIC18F45K22-I/P 8-Bit Flash Microcontroller with XLP Technology DIP-40 (PIC18F45K22-I/P DIP IC)
The PIC18F45K22-I/P is a high-performance, 8-bit Flash microcontroller from Microchip’s enhanced PIC18 "K" series, housed in a standard 40-pin DIP package. This IC is designed to offer a blend of high computational power and eXtreme Low Power (XLP) consumption. It features a powerful RISC architecture with 75 instructions and an internal oscillator that can reach 64MHz using the integrated 4x Phase Locked Loop (PLL). With 32KB of Flash program memory, 1536 bytes of RAM, and 256 bytes of EEPROM, it is well-suited for high-density applications. Key peripherals include a 28-channel 10-bit ADC, dual comparators, and multiple serial communication ports (EUSART, SPI, I2C). Its wide operating voltage and advanced power-managed modes make it a highly efficient solution for modern embedded designs.
This IC is widely utilized in smart energy meters, industrial automation controllers, and battery-operated remote sensors. It is a premier component for Arduino-based electronics projects in India for building DIY multi-channel data acquisition systems, complex robotics controllers, and high-speed serial gateways that require a large number of analog inputs and robust processing in a 40-pin DIP footprint.
