Frequently Asked Questions
What is the maximum clock speed and ADC resolution of the PIC18C242-I/SO?
PIC18C242-I/SO operates at up to 40 MHz and integrates a 10-bit ADC with up to 5 analog input channels, making it suitable for embedded designs that require both fast processing and accurate analog-to-digital conversion in a single 28-pin SOIC chip.
Which serial communication interfaces are available on the PIC18C242-I/SO for connecting sensors and peripherals?
The device includes an MSSP module supporting both SPI and I2C at standard and fast modes up to 400 kHz, plus a USART for asynchronous serial communication at baud rates up to 2.5 Mbps, covering the most common sensor and peripheral interfaces needed in 8-bit embedded applications.
When is PIC18C242-I/SO a better fit than its 40-pin sibling PIC18C452 for cost-sensitive board designs?
PIC18C242-I/SO is the lower-cost, smaller option in the PIC18C family, offering 28 pins instead of 40, which reduces PCB area and device cost in designs that need fewer than 22 I/O lines, 16 KB of program space, and a 10-bit ADC without the overhead of the larger package.
