Microcontrollers Procurement Notes

Verify the specific suffix 'T-I/ML' corresponds to the QFN-28 tape and reel packaging configuration. Confirm the 'I' temperature grade matches the required industrial operating range of -40°C to +85°C. Ensure the 'LF' designation aligns with the lower voltage supply requirements compared to standard F-series variants.

Microcontrollers Selection Notes

Select this component when design constraints require a balance of peripheral density and power efficiency in a small form factor. The QFN-28 package offers a compact footprint suitable for space-limited PCB layouts. Consider the integrated LCD and CapSense modules if external drivers are undesirable, reducing overall bill of materials.

Microcontrollers Part Context

This part belongs to the PIC16(L)F193x family of 28-pin Flash-based microcontrollers. It shares architectural similarities with the PIC16F1933 but is optimized for lower power consumption within a reduced voltage window. The family utilizes the enhanced mid-range CPU core common across the PIC16 architecture.

Microcontrollers Replacement Considerations

The PIC16LF1933-I/ML without the 'T' suffix serves as the tube-packaged equivalent. Other members of the PIC16(L)F193x family may offer increased memory or I/O counts but require verification of pinout compatibility and peripheral availability.
