Microcontrollers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'MX' indicates the UQFN-28 package. Confirm the 'LF' designation ensures operation within the 1.8V to 3.6V voltage range. Ensure compatibility with development tools such as the DM164136 kit if required for prototyping.

Microcontrollers Selection Notes

Select this component when a full-featured CAN peripheral is required alongside high-performance analog capabilities. The inclusion of ADC2 reduces software complexity for signal analysis tasks. Consider the DMA controllers for efficient data handling without CPU intervention. Verify that the 28-pin UQFN package fits the board layout constraints.

Microcontrollers Part Context

This device belongs to the PIC18(L)F25/26K83 family of 28-pin microcontrollers. It shares architectural similarities with the PIC18F25K83 but differs in operating voltage specifications. The family emphasizes low-power operation and extensive peripheral integration for intelligent wired and wireless communication applications.

Microcontrollers Replacement Considerations
