Frequently Asked Questions
What is the minimum supply voltage for the PIC18LF25K22-I/ML and at what clock speed does it run?
The PIC18LF25K22-I/ML operates at a minimum supply of 1.8 V while running at up to 20 MHz. When the supply is raised to 2.0 V to 5.5 V, the maximum clock frequency increases to 64 MHz, giving designers flexibility to trade speed for power consumption based on application requirements.
How does the PIC18LF25K22-I/ML's XLP technology extend battery life in portable designs?
XLP (eXtreme Low Power) technology enables sleep currents below 100 nA in the PIC18LF25K22-I/ML, allowing a 1000 mAh battery to sustain standby operation for years. Combined with fast wake-up from deep sleep, this makes the device ideal for coin-cell powered sensors that spend most of their time idle but require fast response to external events.
What on-chip peripherals does the PIC18LF25K22-I/ML include to minimize external components?
The PIC18LF25K22-I/ML integrates a 10-bit ADC with multiple channels, dual analog comparators, two EUSART serial ports, SPI, I2C, and multiple timer/PWM modules. These built-in peripherals eliminate the need for external ADCs, comparators, or UART ICs in most sensor and communication applications, reducing BOM cost and PCB area.
For a compact IoT sensor node, how does the 28-pin QFN package of PIC18LF25K22-I/ML compare to a DIP alternative?
The PIC18LF25K22-I/ML in 28-pin VQFN (4x4 mm) occupies roughly 16 mm2 of PCB area versus approximately 250 mm2 for a 28-pin DIP package, an over 90% footprint reduction. This space saving is critical in miniature IoT nodes, wearable sensors, and smart labels where PCB real estate is severely limited.
Is the PIC18LF25K22-I/ML compatible with Microchip's MPLAB development ecosystem?
Yes, the PIC18LF25K22-I/ML is fully supported by MPLAB X IDE, the XC8 C compiler, and all Microchip PICkit and ICD debuggers. In-circuit programming and debugging are available through the standard 5-pin ICSP interface, enabling rapid firmware development cycles with no special toolchain setup beyond a standard 5 V or 3.3 V programmer connection.
