AT24RF08C

For example, when SB1 is a 1, the PB1 field can be written

to any value by the system. When the PB1 field is 11, Block

1 can be written by the system. Note that the state of the

SB1 bit does not affect whether or not Block 1 can be

written.

There is no individual page Write Protection for any other

block other than block 0 within the device. Within the

remaining blocks on the chip, access permissions are con-

trolled on a block basis (PB or RF bits) or full chip basis

(WP pin) only.

Write Protection Flow

EEPROM Tamper Latch

There is an additional EEPROM tamper latch that can be

set from the RFID port and reset from the serial port of the

device. Resetting this bit from the serial port takes less

than 10 ms. Setting of this bit from the RFID side when

powered from L1/L2, takes about 7.9 ms but requires less

than 30 µA of current. See “RFID Command” on page 8.

Access to this tamper bit from the serial interface is via the

LSB of the tamper byte of the access protection page. See

“Access Protection Page” below. The bit can only be set to

0 via the serial port. Attempts to write it to a value of one

are ignored.
