- Ultra-low-voltage operation down to 1.8 V at 20 MHz enabling direct interfacing with energy-harvesting circuits and single-cell lithium batteries without a boost regulator
- Integrated ADC with 28-pin SSOP package and lead-free construction supporting analog sensor acquisition in space-constrained industrial and consumer PCB designs
Applications
The PIC18LF25K22-I/SS is well suited for low-power sensor nodes, portable medical monitors, and battery-powered consumer devices that require 8-bit performance with a 1.8 V minimum supply voltage. Its 32 KB Flash supports RTOS-free multi-peripheral firmware, including simultaneous UART, SPI, and I2C drivers alongside ADC-based sensor reading at up to 64 MHz. The 28-pin SSOP package makes it compatible with hand-soldering and standard SMT assembly, providing a cost-effective migration path from PIC16 designs to larger memory and faster clocking.

Frequently Asked Questions
What is the minimum supply voltage for PIC18LF25K22-I/SS, and at which clock speed does it operate at that voltage?
The PIC18LF25K22-I/SS operates from a minimum supply voltage of 1.8 V at up to 20 MHz, and runs at full speed up to 64 MHz from a standard 2.7 V to 3.6 V supply. This 1.8 V capability allows direct use with single-cell LiPo batteries or energy-harvesting power sources without a boost converter.
How does the 32 KB Flash of PIC18LF25K22-I/SS compare to entry-level PIC16 microcontrollers for firmware complexity?
With 32 KB of Flash and 1536 B SRAM, the PIC18LF25K22-I/SS offers 4 to 16 times more program memory than typical PIC16 devices (2 KB to 8 KB Flash). This headroom supports multi-protocol communication stacks, state machine-heavy applications, and event logging that would overflow a PIC16, while staying in the 8-bit cost tier.
What package does PIC18LF25K22-I/SS use, and can it be hand-soldered during prototyping?
The PIC18LF25K22-I/SS uses an SSOP-28 (Shrink Small Outline Package, 28-pin) with 0.635 mm pitch. While finer than standard 1.27 mm SOIC, SSOP-28 is manageable with fine-tipped soldering irons during prototyping and is also compatible with reflow SMT assembly for production volumes.
Which applications benefit from pairing the PIC18LF25K22-I/SS ADC with its low-voltage XLP feature?
Environmental monitoring nodes, wearable health sensors, and smart metering devices benefit most, since they need to sample analog signals (temperature, pressure, or biopotential) at 1.8 V to 3.6 V while keeping quiescent current minimal during sleep intervals. The XLP sleep modes drop the standby current to microampere levels, extending battery life well beyond what standard PIC18 variants can achieve at the same 64 MHz peak clock rate.
