Applications
The PIC18F2320-I/SO is suited for embedded control applications such as home appliance controllers, industrial sensor nodes, and battery-powered data loggers where an 8-bit MCU with on-chip ADC and communication interfaces is required. Its 2 V minimum supply capability makes it a strong choice for energy-harvesting and coin-cell powered IoT edge devices needing reliable non-volatile storage via on-chip EEPROM. The 28-pin SOIC package and broad peripheral set also make it popular in motor control, HVAC panels, and point-of-sale peripherals where PCB space and BOM cost are constrained.

Frequently Asked Questions
What clock frequency and supply voltage range does the PIC18F2320-I/SO support for low-power operation?
The PIC18F2320-I/SO operates up to 40 MHz at 5 V and can run at 4 MHz from a 2 V minimum supply, allowing the designer to trade speed for reduced power draw. This flexibility makes it suitable for battery-powered sensor nodes and energy-harvesting devices where 2 V to 5.5 V supply rails are common.
How many ADC channels does the PIC18F2320-I/SO provide and what is the resolution?
The PIC18F2320-I/SO includes a 10-bit ADC with 10 input channels, enabling simultaneous monitoring of multiple analog sensors such as temperature, pressure, and current inputs. The 10-bit resolution provides 1024 quantization levels, giving a voltage resolution of approximately 4.9 mV at a 5 V reference, which is adequate for most industrial and consumer sensor interfaces.
Which serial communication interfaces are integrated in PIC18F2320-I/SO and what external components are needed?
The PIC18F2320-I/SO integrates USART for RS-232/RS-485, SPI for high-speed sensor buses, and I2C for connecting EEPROMs, RTCs, and display drivers, all requiring no external communication ICs. This integrated peripheral set reduces BOM cost and board space compared to external bridge chips, making it well suited for compact industrial controllers with 28-pin SOIC footprint constraints.
When would a designer select PIC18F2320-I/SO over PIC16F-series devices for a control application?
A designer should select the PIC18F2320-I/SO when the application requires more than 8 KB of program memory, a 16-bit wide instruction word for improved code density, or the enhanced PIC18 instruction set with hardware multiply for signal processing. At up to 40 MHz and with 256 bytes of on-chip EEPROM, it outperforms PIC16F devices in compute-intensive or data-logging tasks without moving to a 16-bit or 32-bit MCU.
