Applications
PIC18F14K22-I/ML is used in home automation controllers, portable data loggers, and smart consumer appliances where a modest 8-bit code base needs non-volatile data storage and low-power standby capability. Its XLP sleep modes and wide supply tolerance also make it suitable for coin-cell and solar-harvesting IoT edge nodes that require infrequent wake-up and sensor reads.

Frequently Asked Questions
How does PIC18F14K22-I/ML's 64 MHz maximum clock compare to standard PIC18 variants at the same Flash size?
PIC18F14K22-I/ML reaches 64 MHz, which is notably higher than the 48 MHz ceiling of many standard PIC18F K-series MCUs. The faster clock allows higher-throughput sensor sampling loops or shorter active-mode bursts followed by longer XLP sleep periods, improving average power efficiency in duty-cycled designs running from 3 V or 3.3 V supplies.
Does PIC18F14K22-I/ML include on-chip non-volatile data storage beyond Flash, and how much can it store?
Yes. PIC18F14K22-I/ML incorporates 256 bytes of internal EEPROM alongside the 16 KB Flash program memory. This EEPROM is byte-erasable and retains data through power cycles without an external serial EEPROM, making it useful for storing calibration coefficients, configuration records, and accumulated sensor readings in portable instrumentation.
What is the minimum operating voltage of PIC18F14K22-I/ML, and how does it affect AA or Li-ion battery designs?
PIC18F14K22-I/ML operates down to 2.3 V at 20 MHz, which covers most of the usable discharge range of two AA alkaline cells (nominally 3 V, declining to about 2.4 V near end of life) and a significant portion of a single LiPo cell (3.0 V at 80% discharge). This allows the MCU to remain functional longer through the battery discharge curve before a brownout reset occurs.
What is the body size of PIC18F14K22-I/ML's QFN-20 package, and what pick-and-place tolerances apply?
The QFN-20 package on PIC18F14K22-I/ML measures 4 mm x 4 mm with 0.5 mm pin pitch and an exposed thermal pad underneath. Placement tolerance is typically ±0.05 mm for modern pick-and-place machines. The thermal pad should be soldered to a ground copper pour with vias for optimal thermal performance during sustained 64 MHz operation.
When is PIC18F14K22-I/ML a suitable step-up from PIC18F13K22 in a product revision?
PIC18F14K22-I/ML doubles the Flash from 8 KB (PIC18F13K22) to 16 KB without changing the 20-pin QFN footprint or pin assignment, enabling a firmware capacity upgrade with no PCB redesign. This makes it the logical choice when a product revision adds features such as a communication stack or data logging that cannot fit in the original 8 KB but still targets the same low-cost, compact form factor.
