Frequently Asked Questions
How fast can the PIC16F1459-I/SO run, and what supply voltage does it require?
The PIC16F1459-I/SO operates at up to 48 MHz when using the internal PLL with a USB clock source, and it runs from a 2.3 V to 5.5 V supply, making it compatible with both 3.3 V and 5 V system designs.
Can the PIC16F1459-I/SO support a USB HID device without an external bridge chip?
Yes. The device integrates a USB 2.0 Full Speed device controller, so a USB HID design needs only a 20-pin SOIC footprint, a 20 MHz crystal or the 48 MHz internal clock path, and minimal passive components to enumerate on a host PC.
What analog measurement capability does the PIC16F1459-I/SO provide for sensor designs?
The microcontroller includes a 12-channel, 10-bit ADC, enabling simultaneous sampling from multiple sensors such as temperature, pressure, or current transducers at up to 100 ksps conversion rate for typical embedded measurement applications.
How does the SOIC-20 package affect PCB area compared to larger PIC packages in the same family?
The 20-pin SOIC body measures approximately 12.8 mm x 7.5 mm with 1.27 mm pitch, offering a compact footprint compared to 28-pin or 40-pin DIP variants and compatible with standard SMT reflow assembly at 1.27 mm pad spacing.
