Key Features
- 8-bit PIC18 CPU core clocked up to 64 MHz enabling fast control loop execution in embedded applications
- Integrated ADC with wide operating voltage: functional from 2.3 V at 16 MHz and 2.5 V at 32 MHz for battery-powered designs
- Compact 40-pin UQFN package (UQFN-40) reduces PCB footprint compared to larger QFP alternatives
- Rich peripheral integration including UART, SPI, I2C, and timers reducing external component count
Applications
The PIC18F46K42-I/MV targets embedded control applications such as motor drives, home automation nodes, and industrial sensor interfaces that require a proven 8-bit architecture with ADC capability at up to 64 MHz. Its low-voltage operation down to 2.3 V makes it suitable for coin-cell or single-cell Li-Ion battery-powered IoT edge devices and wearable controllers. The 40-pin UQFN footprint is preferred in space-critical consumer electronics and medical monitoring equipment where board real estate is at a premium.

Frequently Asked Questions
What is the maximum clock frequency of the PIC18F46K42-I/MV and what supply voltage is required at that speed?
The PIC18F46K42-I/MV operates at up to 64 MHz clock frequency, requiring a standard 3.3 V or 5 V supply at full speed. For lower-power operation, the device can run at 32 MHz from a 2.5 V supply or at 16 MHz from as low as 2.3 V, making it versatile for both high-performance control and battery-constrained applications within the 8-bit PIC18 family.
Which package does the PIC18F46K42-I/MV use, and how does it compare to a standard TQFP-44 footprint?
This variant uses the UQFN-40 package, which is a compact 40-pin quad flat no-lead format with a significantly smaller land area than a 44-pin TQFP. The reduced package size is advantageous in wearable or IoT PCB designs where space is limited, though it requires fine-pitch SMT soldering compared to the exposed-lead TQFP-44 used on other PIC18F46K42 variants.
For a new embedded design starting in 2024, how long is the PIC18F46K42-I/MV expected to remain in production?
Microchip lists a YTEOL (years to end-of-life) value of 7 for the PIC18F46K42-I/MV, suggesting production continuity through approximately 2031 from the assessment date. With a factory lead time of 11 weeks and introduction date of 2017, the part is mature and well-supported, but designers with very long product horizons beyond 7 years should verify current product lifecycle status before committing to high-volume procurement.
