Reset Threshold Voltage  
Hardware Data Protection  
From the factory the 24CXXX is offered in five different  
variations of reset threshold voltages. They are 4.50-  
4.75V, 4.25-4.50V, 3.00-3.15V, 2.85-3.00V and 2.55-  
2.70V. To provide added flexibility to design engineers  
using this product, the 24CXXX is designed with an  
additional feature of programming the reset threshold  
voltage. This allows the user to change the existing  
reset threshold voltage to one of the other four reset  
threshold voltages. Once the reset threshold voltage is  
selected it will not change even after cycling the power,  
unless the user uses the programmer to change the  
reset threshold voltage. However, the programming  
functionisavailableonlythroughthirdpartyprogrammer  
manufacturers. PleasecallCatalystforalistofprogram-  
mer manufacturers who support this function.  
The 24CXXX is designed with the following hardware  
data protection features to provide a high degree of data  
integrity.  
(1) The24CXXXfeaturesaWPpin.WhenWPpin istied  
high the entire memory array becomes write protected  
(read only).  
(2) The VCC sense provides write protection when VCC  
fallsbelowtheresetthresholdvalue(VTH). TheVCC 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
