Microcontrollers Procurement Notes

Verify that the ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'SO' specifies the 18-lead Small Outline Integrated Circuit package. Ensure the specific variant matches the required voltage range of 2.0V to 5.5V for the LF series. Confirm RoHS compliance status through official Microchip documentation or authorized distributors before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a cost-effective 8-bit solution with low-voltage capability is needed. It is suitable for applications requiring moderate code space and integrated analog features like comparators. Consider the PIC16F628A if a higher minimum voltage of 3.0V is acceptable, or the PIC16F627A if less program memory suffices. Evaluate pin compatibility if migrating from older PIC16C62x variants.

Microcontrollers Part Context

This part belongs to the PIC16F62X family, which shares architectural similarities with the PIC16C62x series but utilizes modern CMOS technology. The 'LF' designation indicates a low-voltage process optimized for battery-operated applications. The 'A' suffix typically denotes an updated revision of the silicon with potential minor electrical characteristic improvements over earlier versions.

Microcontrollers Replacement Considerations

The PIC16F628A-I/SO is a direct functional replacement for the PIC16LF628A-I/SO if the application voltage does not drop below 3.0V. For lower voltage requirements, no direct pin-compatible replacement exists within this specific datasheet scope; consider the PIC16LF627A for reduced memory needs.

Microcontrollers FAQ

What is the difference between PIC16F628A and PIC16LF628A?

The primary difference is the operating voltage range. The PIC16F628A operates from 3.0V to 5.5V, while the PIC16LF628A operates from 2.0V to 5.5V, making it suitable for lower voltage applications.

Does the PIC16LF628A have an internal ADC?

No, the PIC16LF628A does not include an Analog-to-Digital Converter. It provides two analog comparators and a programmable voltage reference module instead.

How many I/O pins are available on the PIC16LF628A?

The device provides 16 programmable I/O pins distributed across PORTA and PORTB.
