Key Features

  • 8-bit PIC18 core up to 40 MHz with 32 KB Flash and 1536 bytes RAM for data-intensive control tasks
  • 10-channel 12-bit ADC delivering high-resolution analog measurements from multiple sensor inputs
  • Low-voltage operation down to 2 V minimum supply at 4 MHz, enabling battery-powered applications
  • Compact VQFN-28 package minimizing PCB footprint for space-constrained embedded designs
  • Industrial-temperature grade ('I' suffix) rated for -40°C to +85°C for rugged environments
  • Lead-free, RoHS-compliant package suitable for eco-regulated global markets

Applications

The PIC18F2523-I/ML is well-suited for portable sensor nodes, battery-operated monitoring devices, and compact industrial instruments where the 10-channel 12-bit ADC enables precise multi-signal acquisition in a small VQFN-28 footprint. Its ability to run at 2 V supply makes it a practical choice for energy-harvesting systems, low-power IoT edge nodes, and wearable or handheld measurement tools requiring extended battery life.

Frequently Asked Questions

What ADC resolution and channel count does PIC18F2523-I/ML offer for multi-sensor designs?

PIC18F2523-I/ML integrates a 10-channel 12-bit ADC, allowing designers to simultaneously monitor up to 10 analog inputs with 12-bit resolution, which is suitable for high-accuracy temperature, pressure, and current measurements in industrial or portable instruments.

Can PIC18F2523-I/ML operate reliably from a single Li-ion or two AA-cell battery pack?

Yes, PIC18F2523-I/ML operates at a minimum supply of 2 V at 4 MHz, making it compatible with depleted alkaline or NiMH battery packs, and it scales up to 40 MHz at higher supply voltages, allowing designers to trade off performance and power consumption based on the application duty cycle.

How does the VQFN-28 package of PIC18F2523-I/ML compare to a PDIP-28 in PCB space requirements?

The VQFN-28 package has a much smaller footprint than a PDIP-28 through-hole package—typically around 4 mm x 4 mm—and uses surface-mount pads, enabling far denser PCB layouts with 28 pins accessible on a compact wearable, handheld, or miniaturized industrial controller.

What factory lead time should buyers expect for PIC18F2523-I/ML, and how should safety stock be managed?

The factory lead time for PIC18F2523-I/ML is 6 weeks; procurement teams should maintain at least 8 weeks of safety stock and consider placing scheduled orders with franchised distributors to protect production continuity against demand surges or supply-chain disruptions.
