Frequently Asked Questions
What is the maximum clock frequency supported by PIC18F44J11-I/PT?
The PIC18F44J11-I/PT supports a maximum clock frequency of 48 MHz. At this speed, the 8-bit PIC18 core can execute instructions efficiently, with the device also supporting internal oscillator options from 31 kHz to 32 MHz for power-optimized operation across diverse embedded applications.
How low is the sleep current in XLP mode, and which battery-powered designs benefit from it?
In eXtreme Low Power (XLP) sleep mode, the PIC18F44J11-I/PT achieves currents well below 100 nA, making it suitable for coin-cell or alkaline battery-powered designs. Applications such as wireless sensor nodes, remote meters, and medical wearables that spend most of their time asleep benefit most from this 8-bit MCU's power profile.
When would PIC18F44J11-I/PT be preferred over a larger PIC18F device for a space-constrained design?
For designs constrained to a 44-pin TQFP-44 footprint (10 mm × 10 mm body), the PIC18F44J11-I/PT provides 16 KB Flash, 10-bit ADC with 13 channels, and USB 2.0 in a compact package. Compared to larger 64-pin or 80-pin variants, this MCU reduces board area while retaining the core PIC18 feature set needed for most mid-complexity embedded control tasks.
