Microcontrollers Procurement Notes

Verify the specific ordering suffix 'STX' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required industrial temperature range and voltage operating limits for your design.

Microcontrollers Selection Notes

Select this model when 14 KB of program memory and 1 KB of RAM are sufficient for the application logic. The 28-pin SSOP package is suitable for space-constrained designs requiring 25 general-purpose I/O pins and extensive analog peripheral support.

Microcontrollers Part Context

This part belongs to the PIC16F181 family, which targets small form factor, feature-rich applications. The family shares common architecture and peripheral sets, differentiated primarily by memory sizes and pin counts ranging from 8 to 44 pins.

Microcontrollers Replacement Considerations

PIC16F18155-I/SS serves as a direct pin-compatible alternative in tube packaging. Other family members like PIC16F18175 offer higher memory but require different pinouts.
