PIC16F676-I/P

The PIC16F676-I/P is a 14-pin 8-bit Flash microcontroller from Microchip Technology’s PIC16F mid-range family. With 1792 bytes of Flash program memory, 128 bytes of SRAM, and 128 bytes of data EEPROM, it provides sufficient memory for small embedded control applications. The device integrates an 8-channel 10-bit ADC and dual analog comparators, making it well-suited for sensor interface and measurement applications. The internal oscillator eliminates the need for external clock components, and ICSP allows in-field firmware updates. The industrial temperature rating ensures reliable operation in harsh environments.

The PIC16F676 operates on Microchip’s mid-range 8-bit RISC architecture with a 14-bit instruction word. Most instructions execute in a single cycle at the selected clock frequency. The 8-level hardware stack supports nested subroutine calls and interrupt handling. The 10-bit ADC uses a successive approximation register (SAR) architecture with a sample-and-hold circuit to convert analog inputs to digital values. The dual comparators compare external analog inputs against a programmable voltage reference or each other, generating digital outputs for threshold detection. The internal oscillator provides selectable clock frequencies from 31 kHz to 4 MHz without external components.
