Frequently Asked Questions
What is the maximum clock frequency of the PIC16LF18855-I/ML, and how does voltage affect it?
The PIC16LF18855-I/ML supports a maximum clock frequency of 32 MHz when operating at a standard supply voltage, but it is limited to 16 MHz when the supply voltage drops to 1.8 V. This makes it suitable for battery-powered designs that trade speed for reduced energy consumption across a 1.8 V to 5.5 V supply range.
Which low-power embedded applications are best served by the PIC16LF18855-I/ML?
This device targets IoT sensor nodes, portable medical monitors, and home automation controllers that need mixed-signal capabilities within a 28-pin QFN footprint. Its integrated ADC and DAC channels eliminate external components, and operation down to 1.8 V with 14 KB Flash provides sufficient code space for typical control firmware without exceeding a tight power budget.
How does the 28-pin QFN package of the PIC16LF18855-I/ML compare to a DIP or SOIC option for PCB density?
The 28-pin QFN (VQFN-28) package has a much smaller PCB footprint than a standard 28-pin DIP or SOIC, typically measuring around 5 mm x 5 mm versus roughly 35 mm for a DIP package. This space saving of more than 6x is critical for wearable and handheld designs where board area is constrained to a few square centimeters.
Is the PIC16LF18855-I/ML a cost-effective alternative to 32-bit microcontrollers for simple sensing tasks?
Yes. For applications requiring fewer than 8 channels of ADC input and modest firmware logic under 14 KB, the PIC16LF18855-I/ML offers an 8-bit solution at a lower unit cost than comparable 32-bit ARM Cortex-M0 devices. Its 32 MHz clock and integrated peripherals handle most sensor acquisition and filtering loops with a typical factory lead time of 6 weeks.
