Frequently Asked Questions
Can the PIC18F44J50-I/PT operate directly as a USB 2.0 full-speed device without an external USB controller?
Yes, the PIC18F44J50-I/PT integrates a full-speed USB 2.0 interface operating at 12 Mbps, allowing it to enumerate as HID, CDC, or custom device classes without requiring an external USB controller chip, saving board space and cost.
What is the maximum clock speed and minimum operating voltage for the PIC18F44J50-I/PT?
The PIC18F44J50-I/PT runs at up to 48 MHz and also supports 8 MHz operation from a minimum supply of 2.15V, making it suitable for both high-performance USB applications and low-power battery-powered designs.
How much non-volatile program storage does the PIC18F44J50-I/PT provide compared to the PIC18F46J50?
The PIC18F44J50-I/PT provides 16KB of Flash program memory, while the PIC18F46J50 offers 64KB. Designers needing more code space should consider the 46J50; the 44J50 is sufficient for smaller USB peripheral firmware with 3.8KB RAM available.
Which PCB footprint does the PIC18F44J50-I/PT use and what pin pitch should be planned for during layout?
The PIC18F44J50-I/PT uses a 44-pin TQFP package with 0.8 mm pin pitch. This surface-mount footprint is compatible with standard reflow soldering and supports dense PCB layouts typical of USB peripheral device boards.
