Applications
The PIC18LF8620-I/PT is ideal for industrial data-acquisition systems that need to sample up to 16 analog sensors simultaneously at 10-bit resolution while running real-time control algorithms at 40 MHz. Its 80-pin TQFP package provides ample I/O for complex motor-control or building-automation panels requiring multiple PWM outputs, UART channels, and SPI peripherals on a single MCU. The device also fits medical instrumentation and laboratory equipment where a wide 2 V to 5.5 V supply range allows operation from both battery and regulated bench supplies.

Frequently Asked Questions
How many ADC channels does the PIC18LF8620-I/PT provide, and what is the resolution?
The PIC18LF8620-I/PT integrates a 16-channel 10-bit ADC, delivering 1024 discrete levels per conversion across a selectable reference voltage range. This allows simultaneous monitoring of up to 16 analog sensors such as temperature, pressure, or current-sense inputs without external multiplexers, simplifying board design in multi-channel data-acquisition systems running at up to 40 MHz.
At what supply voltage does the PIC18LF8620-I/PT operate, and how does the LF designation affect application choices?
The LF variant operates from 2 V to 5.5 V, compared to the standard PIC18F8620 minimum of 4.2 V, enabling direct use in 3.3 V logic systems and battery-powered designs where supply can droop below 4 V. The 2 V minimum is particularly valuable for 2-cell alkaline or NiMH battery stacks, extending useful device life as cells discharge well below their nominal 3 V terminal voltage.
For a high-I/O industrial controller, how does the PIC18LF8620-I/PT's 80-pin TQFP compare to smaller 44-pin PIC18 alternatives?
The 80-pin TQFP-80 package exposes up to 70 general-purpose I/O pins versus approximately 35 in a 44-pin QFN, making the PIC18LF8620-I/PT the preferred choice when a design requires more than 6 UART channels, 16 ADC inputs, and multiple PWM outputs on a single chip. Using the larger package avoids adding I/O expander ICs, which would otherwise add I2C latency, BOM cost, and extra board layers.
