• Includes dual operational amplifiers to support external sensor conditioning and analog circuit management.
• Offers flexible peripheral pin select (PPS) routing to allow customizable assignment of input and output signals.

Microcontrollers Applications

• Industrial control systems requiring precise analog measurement and robust digital processing.
• Battery-powered devices benefiting from low-voltage operation and power-saving modes.
• Sensor interface modules utilizing integrated op-amps and high-resolution ADCs.

Microcontrollers Procurement Notes

Verify the specific suffix 'SP' corresponds to the SPDIP-28 through-hole package configuration when sourcing components. Confirm that the '-E' designation indicates the extended industrial temperature range suitable for demanding environments. Cross-reference the manufacturer part number directly with official Microchip documentation to ensure authenticity and correct revision levels before procurement.

Microcontrollers Selection Notes

Select this component when a balance of moderate memory capacity and advanced analog features is required in a through-hole package. The inclusion of operational amplifiers and a computational ADC reduces the need for external analog components. Ensure the design utilizes the available 25 I/O pins effectively given the 28-pin constraint.

Microcontrollers Part Context

This microcontroller belongs to the PIC18(Q)71 family, which emphasizes analog integration alongside standard digital control capabilities. The Q71 series distinguishes itself by embedding operational amplifiers and specialized ADC features not found in earlier PIC18 generations. This model represents a cost-effective solution for applications needing both digital logic and analog signal handling without external support chips.

Microcontrollers Replacement Considerations

The PIC18F26Q71-E/SP serves as a direct functional substitute with increased memory capacity. For surface-mount requirements, the PIC18F25Q71-E/SS variant offers identical electrical specifications in an SSOP-28 package. Verify pin compatibility and software migration efforts when transitioning between these related models.
