- 12-channel 10-bit ADC enables high-resolution multi-sensor acquisition in home appliance and industrial control applications
- 2 V minimum supply at 8 MHz operation allows direct use with two AAA alkaline cells without a boost converter
- SSOP-20 package with 18 GPIO pins delivers higher pin density than standard DIP-20 for compact PCB layouts
Applications
The PIC16F677-I/SS is suited for white goods control panels, battery-powered remote sensors, and small motor controllers requiring multiple analog inputs in a low-pin-count package. Its wide 2 V to 5.5 V supply range and 12-channel ADC make it a practical choice for NTC temperature sensing arrays and resistive sensor multiplexing in cost-sensitive designs.

Frequently Asked Questions
How many ADC channels does PIC16F677-I/SS provide and what is the converter resolution?
The PIC16F677-I/SS provides 12 analog input channels connected to a single 10-bit ADC with a sample-and-hold circuit. The 10-bit resolution yields 1024 discrete levels, giving approximately 4.9 mV per step on a 5 V reference, adequate for NTC thermistor linearization, potentiometer position sensing, and battery voltage monitoring.
At what minimum supply voltage can PIC16F677-I/SS operate and what clock frequency is achievable at that voltage?
The PIC16F677-I/SS operates at a minimum of 2 V supply voltage, achieving 8 MHz clock frequency under those conditions. This enables the device to run directly from two NiMH cells in series at 2.4 V nominal, or from a single LiFeO4 cell, without requiring a voltage regulator in light-load embedded sensor applications.
For a capacitive touch or resistive ladder keypad design, how many free GPIO pins remain after power and oscillator pins?
The SSOP-20 package provides 20 pins total, with 2 for VDD and GND and up to 2 optionally used for an external oscillator, leaving 16 to 18 GPIO pins available. This allows a 4x4 matrix keypad, a 3-digit multiplexed LED display, or an 8-channel resistive ladder with dedicated UART transmit and receive pins simultaneously.
