HEF EE OK with WRITE ?

Hi Henrik
so I am aware of WRITECODE (have never used it) but the endurance on the original part 16F15376 will not suffice

on the 16F1937 which has DataEE HEF and will drop on the same footprint my question is whether PBP WRITE will just work with the same as with standard endurance

16F19176 has DataEE but is not HEF and interestingly on the Microchip selector for the 1937 they say "Consider 16F19176" I guess because it is newer and more capable.

The datasheet for the 16F19176 seems to indicate that the device has actual EEPROM on board and does not mention HEF (High Endurance Flash) so I would expect DATA/READ/WRITE to work with that device.

The 16F1937 looks to be the same, ie having actual EEPROM as opposed to the data memory being a dedicated/special/optimized part of program flash (HEF) so, with that device, I would also expect DATA/READ/WRITE to work.

The 16F15376 however does not have EEPROM so I would not expect DATA/READ/WRITE to work.

Do note that I have not verified this, it's simply based on my interpretation of the datasheets.
