Frequently Asked Questions
How much Flash memory does the PIC18F2620 provide and is 64KB sufficient for Modbus RTU firmware with application logic?
The PIC18F2620 offers 64KB of Flash program memory, which comfortably accommodates a full Modbus RTU slave stack consuming roughly 4KB to 8KB alongside application logic, lookup tables, and EEPROM emulation routines. At 20 MHz with hardware multiply, the PIC18 core processes 16-bit CRC calculations for Modbus frames in under 10 µs, making it well suited for RS-485 industrial sensor nodes.
For a compact industrial data logger, how does the 28-pin SOIC package of the PIC18F2620-I/SO compare to QFN alternatives?
The 28-pin SOIC package measures approximately 17.9 mm x 7.5 mm and is hand-solderable and wave-solder compatible, simplifying prototyping and low-volume assembly without specialized equipment. While a QFN-28 occupies only 4 mm x 4 mm, the SOIC28 is preferred when field repair, manual inspection under 10x magnification, or adaptation to existing PCB tooling is more important than minimizing board footprint.
How does the PIC18F2620's 10-bit ADC performance compare to the PIC16F874 when building a multi-channel voltage measurement application?
Both the PIC18F2620 and PIC16F874 feature 10-bit ADC resolution yielding 1024 steps and approximately 4.9 mV per LSB at 5 V reference. The PIC18F2620 adds 64KB Flash versus the PIC16F874's 7KB, enabling storage of larger calibration tables and more complex linearization algorithms for thermocouple or RTD inputs. The PIC18 architecture also supports hardware multiply completing 8x8-bit operations in a single 50 ns instruction cycle at 20 MHz, accelerating averaging and scaling of ADC readings.
