Key Features

  • 64 MHz maximum clock with nanoWatt XLP technology enables high-speed 8-bit operation while achieving ultra-low sleep current for battery-powered designs
  • Operates down to 2.3 V minimum supply at 20 MHz, broadening compatibility with low-voltage battery chemistries and energy-harvesting systems
  • 28-pin VQFN package minimizes PCB footprint for space-constrained IoT sensor nodes and wearable embedded applications

Applications

PIC18F24K22-I/ML is optimized for battery-powered and energy-harvesting IoT sensor nodes, wearable devices, and remote monitoring systems requiring an 8-bit PIC18 MCU with ultra-low standby current. Its nanoWatt XLP technology extends battery life in applications such as wireless sensor networks, smart meters, and portable medical monitors. The 2.3 V minimum supply and 64 MHz clock flexibility allow designers to trade off speed and power consumption dynamically across operating modes.

Frequently Asked Questions

How low can the supply voltage go on PIC18F24K22-I/ML and at what clock speed?

The PIC18F24K22-I/ML operates at a minimum supply of 2.3 V while running at up to 20 MHz, making it compatible with single-cell Li-ion batteries and two-cell alkaline packs. At the full 64 MHz clock, the device requires a higher supply voltage, allowing designers to balance speed and voltage headroom based on the battery chemistry in use.

What makes nanoWatt XLP technology important for IoT sensor applications using this MCU?

Microchip nanoWatt XLP technology reduces the PIC18F24K22-I/ML sleep current to well below 100 nA, enabling coin-cell-powered IoT nodes to last months or years between battery changes. For applications like wireless temperature loggers or asset trackers that wake periodically to sample an ADC channel and transmit data, minimizing sleep current over long idle windows is the dominant factor in battery life at 3.3 V or 2.3 V supply.

How does the PIC18F24K22-I/ML VQFN-28 package compare to a SOIC-28 for high-density PCB designs?

The VQFN-28 package of PIC18F24K22-I/ML occupies a 5 mm x 5 mm footprint, significantly smaller than a SOIC-28 which spans roughly 17.9 mm in length. This size reduction allows designers of compact wearables, hearing aids, or miniature sensor modules to place the 8-bit PIC18 MCU in areas where a SOIC package would not fit on a 2-layer PCB.

Can PIC18F24K22-I/ML replace PIC18F2420-I/SO in existing designs, and what changes are needed?

PIC18F24K22-I/ML is largely pin- and peripheral-compatible with PIC18F2420-I/SO, both offering 16 KB Flash and 8-bit PIC18 architecture, but the K22 variant runs at 64 MHz versus 40 MHz and adds nanoWatt XLP. Switching from the SOIC-28 to the VQFN-28 package requires a PCB layout change, and firmware running at 40 MHz may need clock configuration updates to take advantage of the 64 MHz maximum operating frequency.
