- 10-channel 10-bit ADC enabling precise multi-sensor analog acquisition without external conversion circuitry
- Wide supply voltage operation from 1.8 V at 16 MHz to 5.5 V at 64 MHz covering battery-powered and 5 V industrial designs
- PIC18 RISC architecture at up to 64 MHz delivering 16 MIPS for high-throughput control loops and protocol stacks
Applications
The PIC18F26K20-I/ML targets IoT sensor nodes, portable medical devices, and home automation controllers requiring a balance of code density, analog measurement, and low-power operation. Its 1.8 V minimum supply at 16 MHz enables direct operation from a single AAA cell or coin battery for extended field deployment. The 28-pin QFN footprint also fits tightly spaced PCB designs in wearables and compact industrial instruments where SOIC packages are too large.

Frequently Asked Questions
How does the PIC18F26K20-I/ML's 1.8 V minimum supply voltage benefit battery-powered IoT applications?
Operating from 1.8 V at 16 MHz allows the PIC18F26K20-I/ML to run directly from a depleted AA alkaline cell or a 2-cell coin battery stack down to end-of-life voltage. This eliminates the need for a boost converter in many low-current sensor nodes, extending battery life by removing the boost converter's quiescent current of 20 µA to 100 µA from the power budget.
What ADC resolution and channel count does PIC18F26K20-I/ML provide for multi-sensor data acquisition?
The PIC18F26K20-I/ML integrates a 10-channel 10-bit ADC, providing 1024-step resolution across up to 10 analog inputs simultaneously selectable via the internal multiplexer. At 64 MHz, the ADC acquisition and conversion time is approximately 2 µs per channel, allowing a full 10-channel scan in under 25 µs for data logging applications sampling at rates up to 40 kSPS.
How does PIC18F26K20-I/ML compare to PIC16F devices for firmware-intensive embedded applications?
The PIC18F26K20-I/ML uses the PIC18 enhanced core with a 16-bit instruction word, hardware multiply, and a larger address space (up to 2 MB program memory addressing), making it more suitable than PIC16 for applications with complex state machines, floating-point math libraries, and USB or Ethernet stacks. The 64 KB flash and 3936-byte RAM also provide 4× to 8× more storage than typical PIC16 devices, reducing firmware partitioning complexity.
What communication peripherals does PIC18F26K20-I/ML include for connecting to sensors and host systems?
The PIC18F26K20-I/ML integrates 2 EUSART modules for UART/RS-485 communication at up to 3.3 Mbps at 64 MHz, plus a MSSP module supporting SPI at up to 16 MHz and I2C at 400 kHz or 1 MHz. These on-chip peripherals allow direct connection to 3-wire SPI sensors, I2C EEPROMs, and RS-485 field buses without additional bridge ICs, simplifying the design of 28-pin embedded systems.
