Key Features
- 64 MHz maximum CPU frequency with scalable operation down to 16 MHz at 2.3 V minimum supply, enabling flexible power-performance trade-offs in battery-powered and mains-connected designs
- 16 kB Flash program memory in an 8-bit PIC18 core provides ample code space for moderate-complexity firmware including communication stacks and sensor data processing
- Integrated ADC (analog-to-digital converter) allows direct connection of analog sensors without external conversion circuitry, reducing BOM cost in measurement and control applications
- 28-pin SPDIP through-hole package simplifies prototyping and hand-assembly for development, education, and low-volume production environments where SMT soldering is not practical
Applications
The PIC18F24K42-I/SP is well suited for low-power sensor nodes, home automation controllers, and industrial monitoring devices where an 8-bit core with integrated ADC and a breadboard-friendly 28-pin DIP package accelerates prototyping. Its ability to operate at 2.3 V minimum supply at 16 MHz makes it appropriate for battery-powered IoT edge devices requiring extended run time between charge cycles. The device is also commonly used in educational and maker applications within the PIC18 ecosystem, benefiting from extensive Microchip XC8 toolchain and MPLAB IDE support.

Frequently Asked Questions
How does PIC18F24K42-I/SP balance speed and supply voltage for battery-powered designs?
PIC18F24K42-I/SP supports multiple operating modes: it runs at full 64 MHz from a 5 V supply, at 32 MHz from a 2.5 V minimum supply, and at 16 MHz from a 2.3 V minimum supply. This stepped voltage-frequency relationship lets designers lower the supply rail in battery-powered products to extend run time while keeping the CPU active for sensor polling and communication tasks, without switching to a different MCU part number.
What are the key differences between PIC18F24K42-I/SP and a typical PIC16 device for a 16 kB firmware project?
Compared to PIC16 devices, PIC18F24K42-I/SP uses the PIC18 enhanced core with a larger 16 kB Flash memory, a 16-bit program counter, and a more capable instruction set that includes hardware multiply instructions. These improvements reduce code size and execution time for arithmetic-intensive routines such as PID control or sensor linearization algorithms. The integrated ADC also avoids the need for external conversion circuitry, which can tip the cost comparison in favor of PIC18 for projects with 28-pin DIP requirements.
Which application scenarios benefit most from the integrated ADC in PIC18F24K42-I/SP?
The built-in ADC of PIC18F24K42-I/SP is particularly valuable in temperature sensing, light measurement, and resistive sensor conditioning applications where analog voltages must be digitized without adding an external ADC chip. At 64 MHz clock speeds, the CPU can also perform oversampling to increase effective ADC resolution beyond the native bit depth. This combination suits HVAC control panels, industrial data loggers, and low-cost medical monitoring prototypes that need analog inputs within a compact 28-pin SPDIP footprint.
What is the factory lead time for PIC18F24K42-I/SP, and how should production planners approach procurement?
PIC18F24K42-I/SP carries a factory lead time of 6 weeks from Microchip's authorized distribution network. Production planners should buffer safety stock or place blanket orders several months ahead for medium to high volume runs, especially given recurring MCU supply constraints. The part is RoHS-compliant and introduced in 2017 with a long production lifecycle (YTEOL 18 years), reducing end-of-life discontinuation risk for designs with multi-year production commitments.
