Microchip Technology PIC12F675-I/P

PIC12F675-I/P  PIC® 12F Microcontroller IC 8-Bit 20MHz 1.75KB 

The PIC12F675-I/P from Microchip Technology is an 8-bit microcontroller (MCU) featuring a compact 8-pin PDIP package, designed for cost-sensitive and space-constrained embedded applications. Built on the high-performance RISC architecture, it operates at up to 20 MHz with a 4 MHz internal oscillator and offers 1.75 KB of Flash program memory, 64 bytes of RAM, and 128 bytes of EEPROM. The device supports a wide voltage range of 2.0V to 5.5V, making it suitable for battery-powered systems. Integrated peripherals include an 8-bit ADC with four channels, a comparator, PWM modules, and GPIO pins with wake-on-change functionality. Its low-power sleep mode and robust industrial temperature range (-40°C to +85°C) enhance its versatility across diverse environments. 

PIC12F675-I/P Key Features

The PIC12F675-I/P excels in delivering analog and digital integration within minimal footprint. It includes a 10-bit ADC for precise sensor interfacing, an analog comparator for real-time signal monitoring, and two PWM modules for motor or LED control. The MCU's internal oscillator eliminates the need for external clock components, reducing BOM cost and board space. Enhanced with Microchip's nanoWatt technology, it achieves ultra-low power consumption in sleep mode (typically <1 µA), extending battery life. Additional features include in-circuit serial programming (ICSP), watchdog timer (WDT), and noise-filtered I/O for reliable operation in electrically noisy environments. 

PIC12F675-I/P Applications

This Microchip MCU is widely used in embedded systems requiring minimal complexity and low power consumption. Typical applications include consumer electronics (remote controls, toys), automotive subsystems (sensor modules, lighting control), home appliances (thermostats, smart switches), and industrial automation (level sensors, safety interlocks). Its analog capabilities make it ideal for temperature monitoring, battery management, and basic motor control. The PIC12F675-I/P is also popular in hobbyist projects and educational kits due to its ease of use and affordability.
