Frequently Asked Questions
At what supply voltages and clock speeds can the PIC18F25K42-I/SO operate, and how does that help battery-powered designs?
The PIC18F25K42-I/SO runs at up to 64 MHz from a 2.7 V to 5.5 V supply, scales to 32 MHz at 2.5 V minimum, and operates at 16 MHz down to 2.3 V. This flexibility allows designers to reduce active current draw in battery-powered applications by lowering the clock to 16 MHz when a single lithium cell drops below 2.5 V, extending runtime without a firmware rewrite.
What onboard analog capability does the PIC18F25K42-I/SO provide for sensor interface designs?
The PIC18F25K42-I/SO includes a 12-bit ADC with multiple input channels, enabling direct connection of analog sensors without external ADC ICs. Paired with integrated UART, SPI, and I2C at 64 MHz, the MCU can acquire, process, and transmit sensor data within a single 28-pin SOIC package, reducing BOM and board area for compact sensor nodes.
How does the PIC18F25K42-I/SO compare to the PIC18F26K42 for cost-sensitive designs with moderate Flash requirements?
The PIC18F25K42-I/SO provides 32 KB Flash, while the PIC18F26K42 doubles that to 64 KB at a higher unit price. For applications where firmware fits within 32 KB — such as simple relay controllers or HVAC sensor interfaces — the PIC18F25K42-I/SO in its 28-pin SOIC package delivers the same 64 MHz PIC18K42 peripheral set at a lower per-unit cost, making it the preferred choice in high-volume production runs.
