Hi, i have a PIC16F1789 with internal EEPROM, i would like to save parameters on power-down for my new project.
The PIC16 runs at 32MHz, it has 256 bytes to save, with all perihpherals running.
So i have these skottky diodes from ebay : 1N60P
And i have these capacitors : 470UF @ 16v.
Will it work ?
I know i should not use chinese parts, i just have these diodes laying around and wanto use them.
Maybe you suggest another diode type ?
I am going for a 0,3v threshold to keep the chip close to 5v.
Will this capacitor be enough of 470UF ?, i seen a schematic they use 1F.
Is this 1N4007 a special diode for this ?, whats so special ?
Do i have to worry about diode-peak-voltage on power on ?, maybe thats why the 1N4007 is so special ?
I read a byte and compare it so i dont overwrite the same, and have a checksum.
Maybe i need other parts ?
thanks
