DESCRIPTION  
The X40420, X40421 combines power-on reset con-  
trol, watchdog timer, supply voltage supervision, and  
secondary supervision, manual reset, and Block  
Lock protect serial EEPROM in one package. This  
combination lowers system cost, reduces board space  
requirements, and increases reliability.  
Applying voltage to V  
activates the power-on reset  
CC  
circuit which holds RESET/RESET active for a period of  
time. This allows the power supply and system oscilla-  
tor to stabilize before the processor can execute code.  
—14 Ld SOIC, TSSOP  
• Pb-free plus anneal available (RoHS compliant)
