Key Features
- 12-bit ADCC with computation engine reduces CPU overhead for sensor acquisition at up to 32 MHz clock frequency
- Integrated CWG (Complementary Waveform Generator) and dual PWMs enable direct motor and power-conversion control without external logic
- Low minimum operating voltage of 2.3 V at 16 MHz supports battery-powered designs with extended runtime
Applications
The PIC16F18446T-I/SS suits cost-sensitive embedded designs such as smart sensors, HVAC controllers, and appliance control panels requiring analog signal conditioning alongside digital communication. Its 12-bit ADCC with hardware computation and built-in DAC and comparator reduce external component count in mixed-signal applications. The 20-pin SSOP footprint and tape-and-reel packaging streamline automated assembly for medium-to-high volume production.

Frequently Asked Questions
What ADC resolution and speed does the PIC16F18446T-I/SS provide for precision sensor measurements?
The PIC16F18446T-I/SS includes a 12-bit ADCC (ADC with Computation) capable of hardware averaging, filtering, and threshold comparison without CPU intervention. Running at up to 32 MHz, it can perform hundreds of conversions per second, making it suitable for temperature sensors, pressure transducers, and other analog front-end applications requiring 12-bit resolution.
Can PIC16F18446T-I/SS operate reliably from a 3 V coin cell or dual-AA battery pack?
Yes. The PIC16F18446T-I/SS operates from a minimum of 2.3 V at 16 MHz clock frequency, covering the useful discharge range of a dual-AA or CR2032 coin cell. At reduced supply voltages, current consumption drops below 100 µA in sleep mode, extending battery life to months or years in duty-cycled IoT sensor nodes.
How does the SSOP-20 package of PIC16F18446T-I/SS compare to a DIP-20 for prototyping versus production use?
The SSOP-20 package has a 0.635 mm pin pitch and occupies roughly 7.5 mm × 5.3 mm of PCB area, about 60% smaller than a DIP-20 footprint. While DIP-20 suits breadboard prototyping, the SSOP-20 with the T suffix tape-and-reel packaging is optimized for automated SMT pick-and-place assembly at production volumes of 1,000 units or more.
