Key Features
- 64 kB Flash program memory with 3936 bytes RAM supporting mid-complexity firmware and RTOS task stacks
- 13-channel 10-bit ADC enabling simultaneous multi-sensor analog measurement in a compact 44-pin QFN footprint
- 1.8 V minimum supply voltage at 16 MHz enabling ultra-low power operation in battery-powered embedded nodes
Applications
The PIC18F46K20-E/ML is ideal for battery-powered sensor nodes, portable medical monitors, and industrial I/O controllers that require multi-channel analog measurement at low supply voltages. Its 13-channel 10-bit ADC and 64 kB Flash make it capable of running sensor fusion algorithms and local data logging without external memory in a compact 44-pin QFN package. The ability to operate at 1.8 V down to 16 MHz reduces system power consumption significantly in always-on monitoring applications.

Frequently Asked Questions
How many analog input channels does PIC18F46K20-E/ML support and what resolution do they provide?
The PIC18F46K20-E/ML integrates 13 analog input channels connected to a 10-bit ADC, providing 1024 discrete output codes with a resolution of approximately 3.2 mV per LSB at a 3.3 V reference. This makes it sufficient for measuring signals from temperature sensors, pressure transducers, potentiometers, and light sensors without requiring an external ADC in most low-to-mid-accuracy applications.
What is the minimum supply voltage for PIC18F46K20-E/ML and how does it affect the maximum clock frequency?
The PIC18F46K20-E/ML can operate at a minimum supply voltage of 1.8 V, but at that voltage the maximum CPU clock is limited to 16 MHz. Raising the supply to 2.0 V allows operation up to 20 MHz, and the full 48 MHz speed is available when the supply is at least 2.3 V. This voltage-frequency scaling is useful for dynamic power management in battery systems where supply voltage drops during discharge.
For a compact 44-pin PCB design, how does the QFN package of PIC18F46K20-E/ML compare to a TQFP footprint of the same pin count?
The 44-pin QFN package of the PIC18F46K20-E/ML has a 7 mm × 7 mm body versus a typical 10 mm × 10 mm body for 44-pin TQFP packages, saving approximately 51% of component footprint area. The QFN also has no exposed lead-forming tolerances, improving co-planarity to under 0.05 mm for more reliable automated solder paste printing and reflow on high-density PCBs.
