Microcontrollers Procurement Notes

Verify the specific suffix 'PT' corresponds to the 40-pin Thin Quad Flat Package (TQFP) configuration in official Microchip documentation. Confirm that the '16' designation aligns with the required operating frequency specifications for your application design. Ensure compatibility with existing development tools and programming hardware before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a balance of code flexibility via EPROM and high-speed processing is required. The PIC17C42A offers architectural enhancements over the standard PIC17C42, including a hardware multiplier. Consider the available package types and voltage ranges to ensure suitability for the target environment and manufacturing volume.

Microcontrollers Part Context

This part belongs to the PIC17C4X group within the broader PIC17CXX family of 8-bit CMOS microcontrollers. The family is characterized by its modified Harvard architecture and orthogonal instruction set. The PIC17C42A specifically serves as an enhanced version of the original PIC17C42, providing improved performance capabilities while maintaining pin compatibility.

Microcontrollers Replacement Considerations

The PIC17C42 is functionally similar but lacks the hardware multiplier found in the PIC17C42A. Users upgrading from the PIC17C42 should verify software compatibility regarding multiplication operations. Other members of the PIC17C4X family may offer different memory sizes or peripheral configurations.
