Frequently Asked Questions
How much memory does PIC18F26K20-E/SS provide and how does it handle firmware with communication stacks?
The PIC18F26K20-E/SS provides 64 KB of Flash program memory and 3968 bytes of RAM, enough to hold a Modbus RTU or CAN protocol stack alongside application code at 48 MHz. This memory configuration fits common industrial communication firmware that requires 8 to 16 KB for protocol handling plus 32 KB for application logic. The RAM capacity supports multi-buffer UART and SPI transfers without running out of working memory in data-intensive control loops.
At what supply voltage can PIC18F26K20-E/SS operate and how does this benefit a 2-cell lithium design?
PIC18F26K20-E/SS runs at a minimum 1.8 V supply at 16 MHz and at 2 V for 20 MHz operation, making it directly compatible with a dual lithium-cell battery that drops from 4.2 V to 1.8 V near end-of-life. This extended voltage range eliminates the need for a boost regulator in many battery applications, saving one IC and reducing quiescent current. At 1.8 V, the nanoWatt sleep mode draws below 100 nA, extending battery life significantly.
How does the 28-pin SSOP package of PIC18F26K20-E/SS compare to the DIP-28 for a dense PCB design?
The SSOP-28 package body measures approximately 10.2 mm x 7.5 mm with 0.65 mm pin pitch, occupying roughly 40% less PCB area than the equivalent DIP-28 at 35.6 mm x 9.8 mm. For a dense sensor hub or motor-control board where PCB space is limited to a few square centimeters, the SSOP-28 fits more easily alongside passive components and connectors. The 28 pins provide 25 I/O lines, sufficient for most standalone control tasks.
How does PIC18F26K20-E/SS compare to PIC18F25K20 when selecting a part for a project expecting firmware growth?
The PIC18F26K20-E/SS doubles the Flash memory to 64 KB compared to the PIC18F25K20's 32 KB, providing headroom for expanded communication protocols, bootloaders, or additional features without requiring a board respin. Both parts share the same 28-pin SSOP footprint, 3968 bytes RAM, and 48 MHz maximum clock, so migration is a drop-in replacement at the PCB level. The larger Flash version is recommended when initial firmware exceeds 20 KB, leaving less than 50% free space for future updates.
