Frequently Asked Questions
What is the maximum clock frequency of the PIC18F65K90-I/MR and what supply voltage does it require at low speeds?
The PIC18F65K90-I/MR runs at up to 64 MHz with a typical 3.3 V supply. It can also operate at as low as 1.8 V when the clock is limited to 4 MHz, making it suitable for battery-powered designs that need to balance performance and power consumption across varying load conditions.
Which display-intensive embedded designs benefit most from choosing the PIC18F65K90-I/MR over a standard PIC18 without LCD support?
Designs such as smart utility meters, industrial HMI panels, and portable test instruments benefit because the integrated LCD controller eliminates an external driver IC, saving board space and BOM cost. With 32 kB Flash and 2 kB RAM on chip, the device handles both application logic and display refresh in a compact QFN-64 footprint.
How does the QFN-64 package of the PIC18F65K90-I/MR compare in board footprint to a TQFP-64 variant?
The QFN-64 package typically measures 9 mm x 9 mm with a 0.5 mm pitch, yielding a smaller PCB land area than a standard TQFP-64 at 10 mm x 10 mm with 0.8 mm pitch. This 10–20% reduction in footprint is useful in space-constrained products. The exposed thermal pad also improves heat dissipation versus the TQFP option.
When would PIC18F65K90-I/MR be a practical alternative to a 32-bit ARM Cortex-M0 MCU for a metering application?
For cost-sensitive metering designs where 8-bit arithmetic is sufficient and the integrated LCD driver removes the need for an external display IC, the PIC18F65K90-I/MR at 64 MHz with 32 kB Flash can match functional requirements at a lower unit price. AEC-Q100-style robustness is provided by the extended industrial temperature range of -40 °C to +85 °C.
