Microcontrollers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the '04E' designation corresponds to the 4 MHz speed grade and commercial/industrial temperature range specifications. Ensure compatibility with existing PCB footprints for the 20-SSOP package before procurement. Cross-reference the manufacturer's current status as this series may be subject to discontinuation notices.

Microcontrollers Selection Notes

Select this component for designs requiring a low-cost 8-bit solution with integrated ADC capabilities. It is suitable for applications where external oscillators are preferred over internal RC options. Consider the limited program memory size for complex firmware requirements. Evaluate the 2.5V to 6V operating range against system power constraints.

Microcontrollers Part Context

This part belongs to the PIC16C55X series of EPROM-based 8-bit microcontrollers. It shares architectural similarities with other members like the PIC16C554 and PIC16C557. The series is characterized by its simple peripheral set and robust RISC core. It serves as a foundational component for basic embedded control tasks.

Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same family include the PIC16LC554 without the reel suffix or the PIC16C554 variants. Verify electrical characteristics such as voltage range and speed grades when substituting. Check for any changes in pinout or peripheral availability between closely related model numbers.
