Microcontrollers Procurement Notes

Verify the specific ordering suffix 'ST' corresponds to the TSSOP-14 package configuration required for your PCB layout. Confirm that the '-E' temperature grade meets your operational environmental specifications. Ensure the design accommodates the shunt regulator's current range requirements as defined in the electrical characteristics section of the datasheet.

Microcontrollers Selection Notes

Select this component when system architecture requires integration of a shunt regulator within the microcontroller to reduce bill of materials cost. Compare against the PIC16F616 variant if external voltage regulation is preferred or if the shunt regulator current handling exceeds system limits. Verify pin compatibility with existing designs using the PIC16F616.

Microcontrollers Part Context

This device belongs to the PIC16HV61x series, which extends the standard PIC16F61x family by adding an internal shunt regulator. This addition allows the microcontroller to interface directly with higher voltage power rails, simplifying circuit design for applications like fan speed control where multiple voltage domains are present.
