Applications
The PIC18F55K42T-I/PT suits embedded control applications such as industrial sensor nodes, home-automation panels, and motor-drive systems that require a balance of computational speed and low standby current. Its 64 MHz clock and rich peripheral set make it a strong fit for IoT edge devices, portable battery-powered instruments, and smart metering designs. The wide supply-voltage tolerance (2.3 V to 5.5 V) enables use across both 3.3 V and 5 V system architectures.

Frequently Asked Questions
What is the maximum clock frequency of the PIC18F55K42T-I/PT and how does it affect real-time processing?
The PIC18F55K42T-I/PT operates at up to 64 MHz, delivering 16 MIPS throughput for single-cycle instruction execution. This speed is sufficient for real-time sensor polling, PID control loops, and serial communication tasks in embedded 8-bit applications without an external co-processor.
At what supply voltage can the PIC18F55K42T-I/PT operate in ultra-low-power mode for battery designs?
Using XLP technology, the PIC18F55K42T-I/PT can operate at 2.3 V when clocked at 16 MHz and at 2.5 V for frequencies up to 32 MHz. This makes the device well-suited for coin-cell or single-cell Li-Ion battery-powered designs where minimizing quiescent current below 1 µA in sleep mode is critical.
How many I/O pins and communication interfaces does PIC18F55K42T-I/PT provide for a multi-peripheral design?
Housed in a 48-pin TQFP package, the PIC18F55K42T-I/PT offers up to 40 general-purpose I/O pins along with multiple UART, SPI, and I2C modules. This peripheral density allows simultaneous connection of sensors, displays, and wireless modules without external expanders in designs operating from 2.3 V to 5.5 V.
When would a designer choose PIC18F55K42T-I/PT over a 32-bit MCU for a cost-sensitive industrial application?
For tasks requiring 8-bit data paths, low code complexity, and sub-1 µA sleep current, the PIC18F55K42T-I/PT provides sufficient 64 MHz performance at a lower unit cost and simpler toolchain compared to 32-bit alternatives. Industrial control panels, smart switches, and sub-10 kHz sensor acquisition systems are prime candidates where the 32 KB Flash and 12-bit ADC meet all requirements without 32-bit overhead.
