Frequently Asked Questions
What program memory and RAM capacity does the PIC18F6390-I/PT provide for firmware development?
The PIC18F6390-I/PT includes 8 KB of Flash program memory and 768 bytes of SRAM, providing enough capacity for moderately complex C firmware including interrupt-driven peripheral handling, a basic menu system, and RTOS-style task switching on an 8-bit PIC18 core running at up to 20 MHz.
What makes the PIC18F6390-I/PT better suited than a generic PIC18F without LCD driver for a smart meter design?
The integrated LCD driver in the PIC18F6390-I/PT directly controls segment displays without requiring an external LCD controller IC, reducing BOM cost by eliminating at least 1 additional chip and simplifying the PCB layout. For a smart meter displaying kWh values on a multi-digit segment LCD, this integration saves board space and reduces assembly cost at volumes above 10,000 units.
Does the PIC18F6390-I/PT include analog measurement capability, and what precision is available?
Yes, the PIC18F6390-I/PT includes a built-in 10-bit ADC, enabling it to digitize analog sensor signals such as temperature from an NTC thermistor or voltage from a shunt resistor directly without an external ADC IC. The 10-bit resolution provides 1024 discrete levels over the reference voltage range, suitable for most consumer and industrial measurement applications.
