Frequently Asked Questions
Does PIC18F13K50-I/SS include a USB interface, and what transfer rate does it support?
Yes, PIC18F13K50-I/SS integrates a USB 2.0 full-speed device controller capable of 12 Mbps data transfers. This eliminates the need for an external USB-to-serial bridge in HID, CDC, or custom class applications, reducing BOM cost and PCB footprint while allowing direct enumeration on Windows, macOS, and Linux hosts.
What is the maximum clock frequency of PIC18F13K50-I/SS and how does it relate to USB operation?
The PIC18F13K50-I/SS runs at up to 48 MHz, which is exactly the frequency required to generate the 48 MHz USB clock from an internal PLL when using a 4 MHz or 8 MHz crystal or the built-in oscillator. This means the MCU can simultaneously run application firmware at full speed while maintaining compliant USB full-speed signaling at 12 Mbps.
How many analog inputs does PIC18F13K50-I/SS provide, and what resolution is the ADC?
PIC18F13K50-I/SS features a 10-bit SAR ADC with multiple selectable input channels sourced from its 15 available I/O pins. The 10-bit resolution provides 1024 discrete levels, corresponding to approximately 3.2 mV per count on a 3.3 V reference, which is adequate for monitoring temperature sensors, potentiometers, and other analog signals in embedded control designs.
How does PIC18F13K50-I/SS compare with PIC18F14K50 for a compact USB HID design in SSOP package?
PIC18F13K50-I/SS and PIC18F14K50 are pin-compatible 20-pin devices, but PIC18F14K50 offers 16 KB Flash versus 8 KB on PIC18F13K50-I/SS and an additional I/O pin in some configurations. If firmware fits within 8 KB Flash and cost is the primary driver, PIC18F13K50-I/SS is the lower-cost option; for applications needing more code space or additional peripherals, upgrading to PIC18F14K50 uses the same 20-pin SSOP footprint with no PCB changes required.
