Applications
The PIC18LF26K22-I/SS is designed for energy-constrained embedded applications such as battery-powered wireless sensors, handheld meters, and smart home control nodes that must sleep for extended periods and wake quickly to process events. Its wide 1.8 V to 3.6 V operating range makes it compatible with single lithium-cell or two-cell AA battery-powered designs without voltage regulators. The combination of 64 KB Flash, a fast 64 MHz clock, and integrated ADC also supports more complex control firmware in compact 28-pin SSOP form factor.

Frequently Asked Questions
How low can the PIC18LF26K22-I/SS supply voltage go, and what clock speed is achievable at that voltage?
The PIC18LF26K22-I/SS can operate from as low as 1.8 V supply voltage, running at up to 20 MHz at that voltage level. At the full 3.3 V to 3.6 V supply range, it can reach the maximum 64 MHz clock frequency, giving designers flexibility to trade power consumption for performance based on the specific application needs.
What memory resources does the PIC18LF26K22-I/SS offer for firmware and runtime data?
The PIC18LF26K22-I/SS provides 64 KB of self-programmable Flash for firmware storage and 3968 bytes of SRAM for runtime variables and stack. There is also integrated EEPROM data memory for non-volatile parameter storage. This combination is well-suited for running moderate-complexity state machines, sensor fusion algorithms, and communication protocol handlers on an 8-bit architecture.
How does the nanoWatt XLP feature of the PIC18LF26K22-I/SS benefit a battery-powered IoT design?
The nanoWatt XLP technology in the PIC18LF26K22-I/SS enables extremely low sleep currents in the range of tens of nanoamps to a few µA, depending on the active peripherals. For a coin-cell-powered IoT node that wakes every 10 seconds to sample a sensor and transmit data, this translates directly into years of battery life from a single CR2032 cell, making it ideal for remote environmental monitors and wireless alarms.
Is the PIC18LF26K22-I/SS suitable for replacing a 5 V PIC18F device in a redesigned low-power product?
The PIC18LF26K22-I/SS is a low-voltage variant of the PIC18F26K22 family, compatible at 3.3 V and running up to 64 MHz, whereas the standard PIC18F26K22 supports up to 5 V. Pin-for-pin replacement in the same 28-pin SSOP package is possible, but designers must verify that all external interfaces—including any 5 V-tolerant signals—are appropriately level-shifted to avoid damaging the 3.6 V maximum I/O rating of the LF variant.
