different between PIC18F2525 and PIC18LF2525

Hello
I wonder what is the different between PIC18F2525 and PIC18LF2525? What “LF” stands for? When do we use LF instead of F?

I can see from the datasheet that PIC18LF2525 have a different voltage, frequency graph. Is it so that PIC18LF2525 can work with lower voltage in frequency range up to 40MHz?

Tanks in advance

LF series chips are essentially lower voltage working.

The normal F 2525 can go much faster... The LF is slower and has a smaller brownout value.. I cant verify this but I have read it somewhere... I pretty sure it was around the 16mhz max speed on the LF range..

In the datasheet the LF can operate from 2 to 5.5v.... But it doesn't mention speed... On the microchip forums topic "pic f vs lf" https://www.microchip.com/forums/m416067-print.aspx.

There doesn't seem to be an answer... "One guy said this the other guy said that" sort of thing..

Trial and error!!

Found it...... Table 19.1 in the datasheet..... only applies to the ADC..... Max frequency is 22.68mhz...
