Applications
The PIC18F25K22-I/ML is well-suited for space-constrained embedded control applications such as compact motor drivers, wireless sensor nodes, and industrial I/O modules where its 28-pin QFN package and XLP sleep current extend battery life. Dual ADC modules allow simultaneous sampling of temperature, pressure, or current sense signals without multiplexer delays, benefiting closed-loop control systems. The 64 MHz operation and multiple UART/SPI/I2C peripherals also make it a capable hub MCU for smart home accessories and portable test instruments.

Frequently Asked Questions
How small is the PIC18F25K22-I/ML package, and what board density does the QFN enable versus a DIP equivalent?
The PIC18F25K22-I/ML uses a 28-pin VQFN package measuring 6 mm x 6 mm with 0.65 mm pin pitch, occupying less than 40% of the PCB area of a comparable 28-pin DIP package. The exposed thermal pad also aids heat dissipation in high-current peripheral applications, and the leadless QFN body improves reliability under vibration compared to leaded DIP packages in the same 8-bit PIC18K22 family.
What is the minimum supply voltage for PIC18F25K22-I/ML at reduced clock speed, and how does this extend battery life?
The PIC18F25K22-I/ML can run from 2.3 V minimum supply at up to 20 MHz, making it compatible with a two-cell alkaline battery pack near end-of-discharge. Combined with its sub-100 nA XLP sleep current, a 3.3 V 1200 mAh coin-cell stack powering the device in sleep mode 99% of the time could sustain operation for several years without replacement, ideal for remote monitoring sensors and building automation nodes.
How many analog input channels does PIC18F25K22-I/ML provide, and can both ADC modules sample simultaneously?
The PIC18F25K22-I/ML provides up to 13 analog input channels shared across its dual 10-bit ADC modules. Each ADC operates independently with its own conversion register and interrupt, enabling sequential or near-simultaneous sampling of two different signals. For example, one ADC can monitor a 4–20 mA current loop while the second samples a 0–5 V analog temperature output, completing both conversions within a single 64 MHz instruction cycle block.
When is PIC18F25K22-I/ML a better alternative to PIC18F25K20 for a new design?
PIC18F25K22-I/ML supersedes PIC18F25K20 by adding a second ADC module and two additional MSSP serial ports, doubling the I2C and SPI peripheral count from one to two each. This allows the K22 to manage more sensors and actuators simultaneously without software bit-banging, and its 64 MHz maximum clock is 6 MHz faster than the K20 variant, providing additional headroom for signal processing tasks at 3.3 V supply.
