Key Features
- 8-bit PIC18 core clocked at up to 40 MHz with 16 KB EPROM for medium-complexity embedded firmware in a 28-pin SOIC
- Integrated ADC enables direct analog signal acquisition without an external converter, reducing BOM cost in sensor-based designs
- Low-voltage operation from 2.5 V minimum at 6 MHz supports battery-powered and energy-constrained industrial applications
Applications
The PIC18LC242-I/SO is well suited for embedded control applications that require analog input capability alongside moderate code density, such as industrial process monitors, battery-operated sensor nodes, and programmable timers. Its 40 MHz maximum clock and 16 KB EPROM provide enough headroom for structured C firmware while the 28-pin SOIC package simplifies PCB layout. Low-voltage operation at 2.5 V enables deployment in 3 V battery systems where power efficiency is critical.

Frequently Asked Questions
At what minimum supply voltage can the PIC18LC242-I/SO operate, and which clock speed is supported at that voltage?
The PIC18LC242-I/SO operates from a minimum supply voltage of 2.5 V when the clock is set to 6 MHz or below. This allows the device to run directly from a two-cell alkaline or a single lithium cell in portable and battery-backed applications without the need for a boost regulator.
How much program memory does the PIC18LC242-I/SO provide, and how does that compare to the entry-level PIC16 family?
The PIC18LC242-I/SO includes 16 KB of EPROM program memory, which is significantly more than the 2–8 KB typically found in entry-level PIC16 devices. This larger capacity accommodates structured C code with multiple modules, making it a practical upgrade path when PIC16 flash space becomes a bottleneck at 40 MHz clock speed.
Does the PIC18LC242-I/SO include an on-chip ADC, and how does this affect sensor interface design?
Yes, the PIC18LC242-I/SO integrates an on-chip ADC, eliminating the need for an external analog-to-digital converter in sensor acquisition designs. This reduces the component count, shrinks PCB area, and lowers BOM cost for applications such as temperature measurement, pressure sensing, or battery voltage monitoring on the same 28-pin SOIC device.
Which package does the PIC18LC242-I/SO use, and what assembly process does it support?
The PIC18LC242-I/SO is housed in a 28-pin SOIC package compatible with standard surface-mount reflow assembly. The SOIC-28 footprint offers a lead pitch of 1.27 mm, making it straightforward to hand-solder during prototyping or to place automatically in production, while fitting comfortably on a two-layer PCB alongside passives and connectors.
