Microcontrollers Procurement Notes

Verify the specific ordering suffix 'I/SP' corresponds to the Industrial temperature range (-40°C to +85°C) and the 28-pin SPDIP package style. Confirm that the component matches the preliminary datasheet revision DS40002171D for accurate electrical specifications. Ensure compatibility with existing PCB footprints designed for SPDIP-28 packages before finalizing procurement orders.

Microcontrollers Selection Notes

Select this model when a 28-pin through-hole solution is required for the PIC18-Q43 family. It provides sufficient memory for complex control algorithms while offering extensive analog peripherals. Consider alternative pin counts like the PIC18F46Q43 or PIC18F56Q43 if additional I/O pins are necessary for the design requirements.

Microcontrollers Part Context

This component belongs to the PIC18-Q43 family of low-power, high-performance microcontrollers. The family shares common architectural features such as the C Compiler Optimized RISC core and XLP technology. Other members include variants with different memory sizes and pin counts, such as the PIC18F25Q43 and PIC18F56Q43, allowing for scalable design options within the same ecosystem.

Microcontrollers Replacement Considerations

Direct substitutes within the same package include other devices from the PIC18-Q43 family with compatible pinouts, such as the PIC18F25Q43 or PIC18F27Q43, provided memory differences are acceptable. Cross-family replacements require careful verification of pin compatibility and peripheral availability.
