Frequently Asked Questions
At what minimum supply voltage does PIC16F15243-I/SO operate, and how does that benefit battery-powered designs?
PIC16F15243-I/SO operates at a minimum of 1.8 V at up to 16 MHz, which allows direct operation from a single lithium coin cell or two AA alkaline cells, significantly extending battery life in wireless sensor nodes and portable consumer devices without a boost converter.
How many ADC channels does PIC16F15243-I/SO provide and what resolution do they offer?
The device integrates a 10-bit ADC with multiple analog input channels shared across the 20 I/O pins, providing sufficient resolution to measure temperature sensors, potentiometers, or light sensors with 1024 discrete levels between ground and the reference voltage supply rail.
When is PIC16F15243-I/SO a practical cost-saving alternative to larger 28-pin PIC devices?
When a design requires fewer than 18 GPIO pins and 3.5KB of program memory is sufficient, PIC16F15243-I/SO in 20-SOIC at typically under $1.00 unit price offers a leaner footprint and lower procurement cost than 28-pin variants, reducing PCB area and assembly cost in high-volume runs.
