Frequently Asked Questions
What is the minimum supply voltage and operating clock speed for PIC24F04KA201-I/SO in ultra-low-power mode?
PIC24F04KA201-I/SO can operate from a minimum supply of 1.8 V at up to 8 MHz using the XLP low-power technology, enabling extended run time from small battery cells such as CR2032 coin cells or single-cell NiMH packs.
How does the integrated CTMU help reduce bill-of-materials cost in a capacitive touch design?
The CTMU (Charge Time Measurement Unit) on PIC24F04KA201-I/SO directly measures the capacitance on touch electrode pins without requiring a separate touch controller IC, which can save $0.50 to $2.00 per board in component costs while keeping firmware control over sensitivity thresholds.
Which package and how many pins should the PCB designer use for PIC24F04KA201-I/SO?
The device comes in a 20-pin SOIC-20 package on 1.27 mm pitch, which fits standard double-sided SMT assembly and leaves enough I/O lines for a UART port, ADC inputs, and GPIO for a compact embedded design.
When would a designer choose PIC24F04KA201-I/SO over an 8-bit PIC16 MCU for a sensor application?
A designer would choose PIC24F04KA201-I/SO when the application needs the efficiency of a 16-bit data path, a 32 MHz clock for faster signal processing, or the built-in CTMU for capacitive sensing, advantages that 8-bit PIC16 parts typically cannot match within the same power budget.
