What are the key features of PIC18F45K22-I/PT?
- 8-bit PIC18 core clocked at up to 64 MHz delivering high performance for embedded control tasks
- XLP (eXtreme Low Power) technology enabling sub-microamp sleep currents for battery-powered applications
- Integrated multi-channel 10-bit ADC supporting analog sensor acquisition without external components
- 44-pin TQFP package operating from 2.3 V at 20 MHz providing flexibility for low-voltage single-supply systems
What is PIC18F45K22-I/PT used for?
The PIC18F45K22-I/PT is well-suited for embedded control applications such as home automation, motor speed control, and industrial sensor nodes that demand a balance of 64 MHz processing performance and XLP ultra-low sleep currents under 1 µA. Its integrated 10-bit ADC and broad peripheral set reduce external component count in portable medical monitors, smart appliances, and HVAC controllers. Designers targeting cost-sensitive, high-volume consumer products benefit from the device's 1-week factory lead time and its wide 2.3 V to 5.5 V supply range.

Frequently Asked Questions
At what maximum clock frequency does the PIC18F45K22-I/PT operate, and how does this compare to running at reduced supply voltage?
The PIC18F45K22-I/PT reaches a maximum clock frequency of 64 MHz at full supply voltage. When the supply is reduced to 2.3 V, the device operates reliably at up to 20 MHz, allowing designers to trade off processing speed for lower dynamic power consumption in battery-operated systems without completely losing MCU functionality.
How does the XLP technology in the PIC18F45K22-I/PT benefit long-life battery applications?
XLP (eXtreme Low Power) technology reduces the device's sleep-mode current to typically under 20 nA at 2 V, enabling coin-cell powered nodes to sustain multi-year lifespans. In a duty-cycled IoT sensor that sleeps 99.9% of the time and wakes every 60 seconds to sample 8 ADC channels and transmit data, XLP sleep current dominates the average consumption budget.
How many I/O pins and ADC channels does the PIC18F45K22-I/PT provide, making it suitable for multi-sensor boards?
The PIC18F45K22-I/PT in its 44-pin TQFP package provides up to 36 general-purpose I/O pins and up to 28 multiplexed ADC input channels connected to the internal 10-bit ADC. This pin count supports connecting multiple analog sensors, digital peripherals, communication buses, and status LEDs simultaneously on a single PCB without external I/O expanders.
For a compact motor-control design, how does the TQFP-44 package of the PIC18F45K22-I/PT help minimize board footprint?
The TQFP-44 package has a body size of approximately 10 mm x 10 mm with 0.8 mm pin pitch. This compact SMD footprint is considerably smaller than equivalent DIP packages, enabling dense PCB layouts where the MCU, gate-drive buffers, current-sense resistors, and power connectors must all fit within a 50 mm x 50 mm motor-control module.
