Microcontrollers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C) as specified in the datasheet. Confirm the package type matches the physical requirements, as this specific part number denotes the PDIP-18 variant. Ensure compatibility with the 1.8V to 5.5V operating voltage range for your power supply design. Cross-reference the latest datasheet revision DS40001453G for any errata or silicon updates before finalizing procurement.

Microcontrollers Selection Notes

Select the PIC16F1847-I/P when an 8-bit MCU with up to 14 KB Flash and 1 KB RAM is required for general-purpose embedded tasks. Choose this component over the PIC16LF1847 if the application demands operation above 3.6V, as the 'F' variant supports up to 5.5V. Consider this model for designs needing multiple timer modules, ECCP/CCP capabilities, and capacitive sensing inputs without external components.

Microcontrollers Part Context

This component belongs to the PIC16(L)F1847 family, which includes 18, 20, and 28-pin variants. The '-I' suffix indicates the industrial temperature grade, while '/P' specifies the Plastic Dual In-line Package (PDIP). It shares architectural similarities with other enhanced mid-range PIC16 devices but offers specific peripheral counts like 12 ADC channels and two MSSP modules.
