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 V_CCsense provides write protection when V_CC

fallsbelowtheresetthresholdvalue(V_TH). TheV_CClock

out inhibits writes to the serial EEPROM whenever V_CC

falls below (power down) V_THor until V_CCreaches the

reset threshold (power up) V_TH
