Frequently Asked Questions
At 1.8 V supply, how fast can PIC18F24K20-I/SS operate and what does this enable for energy harvesting designs?
The PIC18F24K20-I/SS runs at up to 16 MHz from a 1.8 V supply, and extends to 20 MHz at 2 V. This capability allows energy harvesting systems using thin-film solar cells or RF energy harvesters producing 1.8 V to 2.5 V to power the microcontroller directly without a boost converter.
How many analog inputs can PIC18F24K20-I/SS sample simultaneously, and how does this fit a multi-sensor data logger?
The PIC18F24K20-I/SS offers multiple 10-bit ADC input channels capable of sampling various sensors including temperature, humidity, and pressure transducers within a single scan cycle. At 64 MHz, ADC conversions complete in under 2 µs each, enabling a 16-channel scan rate above 30 kHz for real-time multi-parameter logging applications.
For a smart meter application using coin cells, why is PIC18F24K20-I/SS a strong candidate over competing 8-bit MCUs?
The PIC18F24K20-I/SS nanoWatt technology enables sleep currents below 50 nA and full-speed operation at 1.8 V, extending CR2032 coin cell life beyond 5 years in duty-cycled meter designs. Competing 8-bit MCUs requiring 2.7 V minimum and drawing 200 nA+ in sleep shorten battery life by 30% or more in similar applications.
What rework advantages does the SSOP-28 package of PIC18F24K20-I/SS provide compared to QFN variants?
The PIC18F24K20-I/SS SSOP-28 package has exposed gull-wing leads on 0.635 mm pitch, making it visually inspectable and hand-solderable with standard soldering irons. Unlike QFN packages with hidden bottom pads, the SSOP-28 allows rework, flux cleaning inspection, and joint quality verification using optical microscopy without X-ray equipment.
