Applications
The PIC18LF25K22-I/SO is ideal for battery-powered sensor nodes, smart home appliances, and portable medical devices that require reliable 8-bit processing at minimal standby current. Its XLP technology allows operation from a 1.8 V supply, making it suitable for single-cell lithium or AA-battery designs in IoT edge devices and wireless sensor motes. Industrial control panels and HVAC controllers also benefit from its broad peripheral set including USART, SPI, I2C, timers, and an on-chip ADC for multi-channel sensor acquisition.

Frequently Asked Questions
At what supply voltage and clock speed does PIC18LF25K22-I/SO achieve its best power-performance balance for a battery-powered sensor?
The PIC18LF25K22-I/SO can run at up to 64 MHz from a 1.8 V to 3.6 V supply, enabling high-throughput sensing bursts followed by deep-sleep periods measured in nanoamps. For a typical coin-cell design at 2 V, reducing the clock to 20 MHz is sufficient for most sensor tasks while keeping active current well below 1 mA, extending battery life significantly compared to standard 5 V MCUs.
How much non-volatile program storage does the PIC18LF25K22-I/SO provide, and is it enough for a FreeRTOS-based firmware image?
The PIC18LF25K22-I/SO includes 32 KB of self-programmable Flash memory and 256 bytes of EEPROM for data storage. A minimal FreeRTOS port for PIC18 typically fits within 12–16 KB, leaving 16 KB or more for the application layer, making this device well-suited for small RTOS-based designs such as motor controllers or protocol-bridge modules with modest task counts.
Which communication interfaces are built into PIC18LF25K22-I/SO for connecting to sensors and host processors?
The PIC18LF25K22-I/SO integrates two USART modules (supporting RS-232 and RS-485 at standard baud rates up to 115200 bps), one MSSP module configurable as SPI or I2C up to 10 MHz, and one additional MSSP. This gives designers 4 independent serial channels for connecting to multiple sensors, displays, or cloud gateway modules without external UART expanders.
When is PIC18LF25K22-I/SO a better fit than PIC18F25K22 for a design powered from a single Li-primary cell?
The 'LF' variant (PIC18LF25K22-I/SO) is specifically rated for 1.8 V minimum supply and features enhanced XLP sleep currents below 100 nA, whereas the standard PIC18F25K22 requires a minimum of 2 V. On a 3.0 V lithium primary cell that droops toward 2 V at end-of-life, the LF variant continues operating reliably while the standard device may reset, making the LF the correct choice for long-lifetime tamper detectors, gas meters, and utility sensors.
How many ADC channels does PIC18LF25K22-I/SO offer, and at what resolution?
The PIC18LF25K22-I/SO includes a 10-bit successive-approximation ADC with up to 17 multiplexed input channels, sufficient for multi-sensor acquisition in applications such as temperature, pressure, and current monitoring. The 10-bit resolution yields 1024 discrete levels, providing approximately 4.9 mV per step when referenced to a 5 V rail, or about 1.8 mV per step at 1.8 V, which meets the accuracy requirements of most industrial transducer readout circuits.
