CAT24CXX1/XX2

Hardware Data Protection

falls below (power down) VTH or until V_CCreaches the

reset threshold (power up) V_TH

TheCAT24CXXXisdesignedwiththefollowinghardware

data protection features to provide a high degree of data

integrity.

Reset Threshold Voltage

The CAT24CXXX is offered with five reset threshold

voltage ranges. They are 4.50-4.75V, 4.25-4.50V, 3.00-

3.15V, 2.85-3.00V and 2.55-2.70V.

(1) The CAT24CXXX features a WP pin. When the WP

pin is tied high the entire memory array becomes write

protected (read only).

(2) The V_CCsense provides write protection when V_CC

fallsbelowtheresetthresholdvalue(VTH).TheV_CClock

out inhibits writes to the serial EEPROM whenever V_CC
