Technical Data

EEPROM features include:
The 512 bytes of EEPROM-1 can be programmed or erased without an
external voltage supply. EEPROM cells are protected with a non-volatile
block protection option. These options are stored in the EEPROM
non-volatile register (EENVR1) and are loaded into the EEPROM array
configuration register after reset (EEACR1) or a read of EENVR1.
Hardware interlocks are provided to protect stored data corruption from
accidental programming/erasing.
The unprogrammed state is a logic 1. Programming changes the state to
a logic 0. Only valid EEPROM bytes in the non-protected blocks and
EENVR1 can be programmed. When the array is configured in the
redundant mode, programming the first 256 bytes also will program the
last 256 bytes with the same data. Programming the EEPROM in the
non-redundant mode is recommended. Program the data to both
locations before entering redundant mode.
