EEPROM writes

[jellis00]

Read table 28-1, 100K erase-write cycles typical and 10k minimum (for each cell).

Thanks, languer for this info. Do you know the answer to my other question as to whether intermittent flashing success is an indication of end of programming life?

If you really believe you have probably flashed it that much, then it certainly could be.

My Pic did die in less than 2 day.

I only have 5VDC available to the board. I added a diode in between the 5V rail and the PIC. I put a 220uf cap across catode of the diode feeding the pic with 4.3V. I then monitor 5V rail for loss of power. When this pin goes low i write the necessary info to the EEPROM. This works fine except for the PWM out will only go up the the 4.3V now instead of the original 5V. I can put a shotkey diode in that should give me another .3V or .4V. Does anyone have a better option to monnitor loss of power and save a vairable?

Thanks,

Terry

Hi,

you can use a MC33064P5 ( TO92 Package ) as a voltage ref : its output will turn low if voltage goes under 4.65v ...

enough time to save data to EEPROM, then ...
