No! The chip/bulk erase algorithm is different, so it is impossible with 
(unmodified firmware of) Wisp628 to erase the chip. Depending on the 
settings of the config bits this could make re-programming impossible.

I'm currently wresting with a 18F2480. The write seems to work, but 
verify fails. Reading back gives differences. Some config bits are 
different (CPD and WRTD), the first 2K bytes of programm memory read 
back as all 0x00 and most ID bytes are 0xFF.
