What are the key features of PIC16F18426-I/JQ?
- 28 KB flash and 2 KB RAM with 12-bit ADCC and on-chip DAC for precision analog measurement and generation in an 8-bit core
- Integrated CWG, dual PWMs, comparator, EUSART, SPI, and I2C peripherals reduce external component count
- Operates from 2.3 V minimum at 16 MHz in an ultra-compact 16-pin UQFN package for space-constrained IoT designs
What is PIC16F18426-I/JQ used for?
PIC16F18426-I/JQ suits compact sensor transmitter designs, motor control, and IoT edge nodes requiring a rich peripheral set in the smallest possible footprint. The 12-bit ADCC with computation hardware and on-chip DAC allow closed-loop analog control without an external ADC or DAC IC. Running from 2.3 V at up to 32 MHz, it powers down to near-zero sleep current in handheld metering and wearable sensor applications.

Frequently Asked Questions
What memory capacity does PIC16F18426-I/JQ offer and how does the 12-bit ADCC differ from a standard ADC?
PIC16F18426-I/JQ integrates 28 KB of flash program memory and 2 KB of RAM. Its 12-bit ADCC (ADC with Computation) includes hardware averaging, threshold comparison, and low-pass filter modes that offload common DSP tasks from the CPU core. A standard 10-bit ADC would require software loops to implement the same averaging, consuming MCU cycles that the ADCC handles autonomously at up to 32 MHz.
Can PIC16F18426-I/JQ run reliably from a single AAA or coin cell at reduced clock speed?
Yes. PIC16F18426-I/JQ operates from a minimum supply of 2.3 V, which is within the usable voltage range of a single AA or AAA alkaline cell (1.5 V nominal, but two-cell packs give 3 V) or a 3 V CR2032 coin cell. At 16 MHz and 2.3 V, all core peripherals remain active, letting designers build battery-powered temperature loggers, wireless sensor nodes, or remote controls with multi-year battery life.
How small is the UQFN-16 package of PIC16F18426-I/JQ and when is it preferable to a SOIC-20?
The 16-pin UQFN package measures approximately 3 mm × 3 mm, occupying roughly 9 mm² of PCB area versus about 125 mm² for a standard SOIC-20. When board area per component must stay below 15 mm², such as in hearing aids, smart labels, or miniature industrial sensors, the UQFN-16 is the only viable choice. Designers should ensure reflow capability since the thermal pad and 0.5 mm pitch require controlled solder paste deposition.
