PRELIMINARY X40420, X40421 4kbit EEPROM Dual Voltage Monitor with Integrated CPU Supervisor and System Battery Switch FEATURES • Dual voltage detection and reset assertion —Three standard reset threshold settings (4.6V/2.9V, 4.6V/2.6V, 2.9V/1.6V) —VTRIP2 programmable down to 0.9V —Adjust low voltage reset threshold voltages using special programming sequence —Reset signal valid to VCC = 1V —Monitor two voltages or detect power fail • Battery switch backup •VOUT: 5mA to 50mA from VCC; or 250µA from VBATT • Fault detection register • Selectable power-on reset timeout (0.05s, 0.2s, 0.4s, 0.8s) • Selectable watchdog timer interval (25ms, 200ms, 1.4s, off) • Debounced manual reset input • Low power CMOS —25µA typical standby current, watchdog on —6µA typical standby current, watchdog off —1µA typical battery current in backup mode • 4Kbits of EEPROM —16 byte page write mode —Self-timed write cycle —5ms write cycle time (typical) • Built-in inadvertent write protection —Power-up/power-down protection circuitry —Block lock protect 0 or 1/2, of EEPROM • 400kHz 2-wire interface • 2.7V to 5.5V power supply operation • Available packages —14 Ld SOIC, TSSOP • Pb-free plus anneal available (RoHS compliant) • Monitor voltages: 5V to 1.6V • Memory security • Battery switch backup •VOUT 5mA to 50mA APPLICATIONS • Communications equipment —Routers, hubs, switches —Disk arrays • Industrial systems —Process control —Intelligent instrumentation • Computer systems —Desktop computers —Network servers X40420, X40421 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 VCC activates the power-on reset 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.
