DESCRIPTION

These devices combine three popular functions, Power-

on Reset Control, Supply Voltage Supervision, and

Block Lock Protect Serial EEPROM Memory in one

package. This combination lowers system cost, reduces

board space requirements, and increases reliability.

Applying power to the device activates the power on

reset circuit which holds RESET/RESET active for a

period of time. This allows the power supply and oscilla-

tor to stabilize before the processor can execute code.
