What are the key features of PIC16F17146-I/SS?
- 32 MHz PIC16 core with 28 KB Flash and 512 B RAM supporting complex control firmware in a compact 20-pin SSOP footprint
- 12-bit differential ADCC with computation unit enabling hardware signal averaging and threshold comparison without CPU intervention
- Integrated operational amplifier eliminating an external op-amp IC for sensor signal conditioning in cost-sensitive designs
- Dual 2x16-bit PWM modules providing high-resolution motor drive and LED dimming control with independent period and duty-cycle registers
- 1.8V to 5.5V wide supply range covering both coin-cell and USB-powered applications with a single hardware design
What is PIC16F17146-I/SS used for?
The PIC16F17146-I/SS is deployed in smart sensor modules where its 12-bit differential ADCC directly digitizes low-level signals from thermocouples, pressure bridges, or current-sense resistors with on-chip gain, removing the need for an external instrumentation amplifier. Its integrated op-amp and dual 16-bit PWM channels make it well-suited for brushed DC motor speed control and fan regulation in home appliances and HVAC systems. The 28 KB Flash and 32 MHz clock also support small IoT edge nodes that collect and pre-process sensor data before transmitting over UART or I2C to a wireless module.

Frequently Asked Questions
How does the 12-bit differential ADCC in the PIC16F17146-I/SS reduce external component count in a thermocouple measurement design?
The differential ADCC with on-chip computation unit can average up to 256 samples in hardware and apply a programmable threshold interrupt, so a thermocouple millivolt signal can be amplified by the integrated op-amp, digitized at 12-bit resolution, and filtered—all without an external instrumentation amplifier or digital filter library consuming the 32 MHz CPU.
For a 3-phase brushless DC fan controller, what PWM resolution does the PIC16F17146-I/SS provide and at what switching frequency?
The dual 2x16-bit PWM modules can be configured with 16-bit period registers to achieve switching frequencies from below 1 kHz up to several hundred kHz; at 32 MHz clock and a 20 kHz target frequency, the resolution exceeds 10 bits of duty-cycle steps, sufficient for smooth fan speed control without audible stepping artifacts.
Which supply voltage range does the PIC16F17146-I/SS support and how does that affect coin-cell IoT sensor designs?
The MCU operates from 1.8V to 5.5V, allowing it to run directly from a CR2032 coin cell whose terminal voltage drops from 3.0V to below 2.0V over its discharge curve, so an IoT sensor node can continue operating without a boost regulator until the cell is nearly exhausted, reducing BOM by 2 to 3 components.
How does the 20-pin SSOP package of the PIC16F17146-I/SS simplify board layout for a compact motor driver reference design?
The SSOP-20 package places all I/O pins on two parallel rows with 0.65 mm pitch, fitting within a 7 mm x 4 mm PCB area, and its small outline allows direct adjacency to a gate-driver IC on a 4-layer board without requiring blind vias, keeping a single-motor driver reference design under 20 mm x 30 mm.
