Key Features
- PIC18 8-bit CPU at 40 MHz with enhanced instruction set delivering higher throughput than PIC16 family controllers
- Operates from as low as 2V supply enabling battery-powered designs with two-cell AA or LiPo power sources
- Integrated multi-channel 10-bit ADC for direct analog sensor acquisition without external converter components
- 28-pin skinny 0.3-inch DIP package for easy breadboard prototyping and through-hole production assembly
Applications
The PIC18F242-I/SP is well suited for home automation nodes, sensor data loggers, and portable measurement instruments where a mid-range 8-bit controller with ADC capability is needed. Its 2V minimum supply voltage enables use with low-battery power rails and energy-harvesting systems, extending operational life in remote or battery-constrained deployments. The familiar skinny DIP28 footprint simplifies prototyping on standard breadboards and through-hole PCBs during development.

Frequently Asked Questions
How does the PIC18F242-I/SP's 40 MHz clock and enhanced instruction set compare to PIC16 devices for embedded control?
The PIC18F242-I/SP executes one instruction per 25 ns at 40 MHz on its enhanced PIC18 core, providing roughly 10 MIPS throughput. Compared to PIC16 parts at 20 MHz, this doubles the available instruction bandwidth while the PIC18 16-bit-wide instruction word reduces code size, benefiting firmware that handles multiple peripherals or complex state machines in a single cycle budget.
Which analog sensing scenarios benefit from the integrated 10-bit ADC of the PIC18F242-I/SP?
The integrated 10-bit ADC supports multiple input channels, providing 1024-count resolution suitable for temperature sensors, potentiometers, light sensors, and battery voltage monitoring in embedded systems. At 40 MHz clock, the ADC conversion can complete within a few microseconds, enabling high-speed sampling loops without an external SPI or I2C ADC and its associated communication overhead.
Can the PIC18F242-I/SP run from a single AA or LiPo battery without a boost converter?
Yes, the PIC18F242-I/SP specifies operation down to 2V minimum supply, which covers a nearly discharged single-cell LiPo at 3V nominal or a nearly depleted AA battery. This eliminates the need for a boost converter in low-power sensor nodes, reducing BOM cost and quiescent losses, though maximum clock speed may be derated below 20 MHz at voltages under 4.2V.
How does the skinny DIP-28 package of PIC18F242-I/SP simplify hardware prototyping compared to surface-mount alternatives?
The 0.3-inch skinny DIP-28 format fits directly into standard breadboards and DIP IC sockets without adapters, allowing immediate hand-wiring of prototypes. Through-hole soldering on perfboard or stripboard is straightforward, and the 2.54 mm pin pitch is compatible with most through-hole PCB design rules. This contrasts with SSOP or QFN packages that require solder adapters or hot-air rework for prototype-stage exploration.
