PIC16F676-I/P 8-Bit Flash Microcontroller with 10-Bit ADC DIP-14 (PIC16F676-I/P DIP IC)
The PIC16F676-I/P is a high-performance, 8-bit Flash-based microcontroller from Microchip's mid-range family, offering a sophisticated set of features in a compact 14-pin package. It features a powerful RISC architecture with 35 single-word instructions. This IC includes 1.75KB of Flash program memory, 64 bytes of SRAM, and 128 bytes of high-endurance EEPROM. A key highlight is the integrated 8-channel 10-bit Analog-to-Digital Converter (ADC) and a dual analog comparator module. With its precision internal 4MHz oscillator and mixed-signal capabilities, it is a highly efficient choice for space-constrained applications requiring precise analog sensing and data persistence.
This IC is primarily used in light sensors, battery chargers, and automotive interior controls. It is a highly popular component for Arduino electronics projects in India for building DIY digital voltmeters, compact sensor interfaces, and smart home automation nodes that require high-resolution analog readings in a small 14-pin DIP footprint.
