Hardware Data Protection
The CAT1161/2 is designed with the following
hardware data protection features to provide a high
degree of data integrity.
(1) The CAT1161/2 features a WP pin. When the WP
pin is tied high the entire memory array becomes
write protected (read only).
(2) The VCC sense provides write protection when VCC
falls below the reset threshold value (VTH). The
VCC lock out inhibits writes to the serial EEPROM
whenever VCC falls below (power down) VTH or
until VCC reaches the reset threshold (power up)
VTH. Any attempt to access the internal EEPROM
is not recognized and an ACK will not be sent on
the SDA line when RESET or RESET
¯¯¯¯¯¯ is active.
Reset Threshold Voltage
The CAT1161/2 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.
