Thread: PIC16F877 Data EEPROM write times

p.157 of 30292b.pdf (16F877 data sheet):
Param No. D122 - erase/write cycle time for Data EEPROM memory:
4 ms Typ, 8 ms Max
Looks like it has to be one byte per write cycle (unlike, for example,
the 24LC01 we use a lot - you can get 8 bytes per write cycle).
