型號(hào)： X5325PIZ

類別： 集成電路

描述： DESCRIPTION These devices combine four popular functions, Power-on Reset Control, Watchdog Timer, 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. FEATURES ? Selectable watchdog timer ? Low VCC detection and reset assertion ?? —Five standard reset threshold voltages ?? —Re-program low VCC reset threshold voltage using special programming sequence ?? —Reset signal valid to VCC = 1V ? Determine watchdog or low voltage reset with a volatile flag bit ? Long battery life with low power consumption ?? —<50μA max standby current, watchdog on ?? —<1μA max standby current, watchdog off ?? —<400μA max active current during read ? 32Kbits of EEPROM ? Built-in inadvertent write protection ?? —Power-up/power-down protection circuitry ?? —Protect 0, 1/4, 1/2 or all of EEPROM array with Block Lock? protection ?? —In circuit programmable ROM mode ? 2MHz SPI interface modes (0,0 & 1,1) ? Minimize EEPROM programming time ?? —32-byte page write mode ?? —Self-timed write cycle ?? —5ms write cycle time (typical) ? 2.7V to 5.5V and 4.5V to 5.5V power supply operation ? Available packages ?? —14 Ld TSSOP, 8 Ld SOIC, 8 Ld PDIP ? Pb-free plus anneal available (RoHS compliant)
