What are the key features of PIC18F26K20-E/ML?
- 64 KB Flash program memory and 3968 bytes RAM providing ample code and data storage for complex 8-bit embedded applications
- Wide supply voltage operation: 1.8 V at 16 MHz or 2 V at 20 MHz, enabling ultra-low-power battery-powered designs
- 28-pin VQFN-28 QFN package with 25 I/O lines offering high I/O density in a compact SMT footprint
What is PIC18F26K20-E/ML used for?
The PIC18F26K20-E/ML is designed for space-constrained embedded control systems in consumer electronics, portable instruments, and IoT edge nodes that require 8-bit processing with up to 48 MHz throughput. Its 64 KB Flash and 3968-byte RAM provide sufficient resources for bootloaders, sensor fusion algorithms, and communication stacks on a single chip. The 1.8 V minimum supply operation extends battery life in always-on monitoring devices by allowing the processor to run at 16 MHz from a deeply discharged Li-ion cell.

Frequently Asked Questions
What is the maximum clock frequency of the PIC18F26K20-E/ML and how does supply voltage affect it?
The PIC18F26K20-E/ML operates at a maximum of 48 MHz from a standard 3.3 V or 5 V supply. At reduced supply voltages the device can still run at 20 MHz from 2 V and at 16 MHz from 1.8 V, allowing designers to trade speed for lower power consumption in battery-operated applications.
How does the 64 KB Flash and 3968-byte RAM of the PIC18F26K20-E/ML compare to typical 8-bit MCU memory sizes?
The PIC18F26K20-E/ML offers 64 KB of Flash program memory and 3968 bytes of SRAM, which is larger than many entry-level 8-bit PIC devices with 8 KB to 32 KB Flash. This expanded memory supports bootloaders, USB protocol stacks, and more sophisticated sensor fusion code within a single 8-bit MCU.
Which compact assembly processes benefit from the PIC18F26K20-E/ML VQFN-28 package?
The 28-pin VQFN package of the PIC18F26K20-E/ML has a 6 mm × 6 mm body with 0.65 mm lead pitch and an exposed thermal pad, making it suitable for automated SMT pick-and-place and reflow assembly. The QFN package reduces PCB footprint by roughly 50% compared to a 28-pin SOIC, benefiting high-density portable product designs.
Can PIC18F26K20-E/ML replace PIC18F25K20 and what are the main differences?
The PIC18F26K20-E/ML (64 KB Flash, 3968 bytes RAM) is the higher-memory variant compared to the PIC18F25K20 (32 KB Flash, 1536 bytes RAM). Both share the same 28-pin pinout and 48 MHz PIC18 core, so dropping in the 26K20 variant doubles the program memory and nearly triples the SRAM for applications that need more code space.
