- 13-channel 10-bit ADC for direct multi-sensor acquisition without external analog front-end components
- Wide voltage operation: 1.8 V at 16 MHz or 2 V at 20 MHz, enabling ultra-low-power battery-operated designs
Applications
The PIC18F43K20-I/PT is well-suited for industrial sensor hubs, home automation controllers, and consumer appliance control boards where its 13-channel 10-bit ADC handles multiple analog inputs simultaneously. Operating down to 1.8 V at 16 MHz makes it a strong candidate for energy-harvesting nodes and coin-cell-powered wireless sensors. Its 44-pin TQFP footprint and 64 MHz headroom also support compact motor control and lighting dimmer designs requiring precise PWM generation.

Frequently Asked Questions
What is the lowest supply voltage at which the PIC18F43K20-I/PT can operate, and at what clock speed?
The PIC18F43K20-I/PT can operate at a minimum of 1.8 V supply voltage while running at 16 MHz, and at 2 V when clocked at 20 MHz. This low-voltage operation makes the device well-suited for 2-cell NiMH, single-cell LiPo, or energy-harvesting applications that must sustain MCU operation as the supply voltage decays during discharge.
How many ADC channels does the PIC18F43K20-I/PT provide, and what resolution do they offer?
The PIC18F43K20-I/PT integrates 13 ADC input channels with 10-bit resolution, producing 1024 output codes across the reference voltage range. This multi-channel capability is valuable for industrial systems that simultaneously monitor temperature, pressure, current, and voltage signals, reducing the need for external multiplexers or analog front-end ICs in a 6-week lead-time design.
For a compact multi-sensor data logger, how does the PIC18F43K20-I/PT's 44-pin TQFP package compare to a 28-pin DIP alternative?
The 44-pin TQFP package of the PIC18F43K20-I/PT provides a significantly smaller PCB footprint than a 28-pin DIP while adding more I/O pins and the full 13-channel 10-bit ADC. The TQFP surface-mount profile enables automated SMD assembly and tighter board layouts in multi-layer PCBs for data loggers, whereas a DIP requires through-hole drilling and more board area — making the TQFP-44 the preferred choice for volume production at 64 MHz performance.
