Overview
X5083 CPU Supervisor with 8Kbit SPI EEPROM FEATURES • Low VCC detection and reset assertion —Four standard reset threshold voltages 4.
63V, 4.
38V, 2.
93V, 2.
63V —Re-program low VCC reset threshold voltage using special programming sequence.
—Reset signal valid to VCC = 1V • Selectable time out watchdog timer • 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 • 8Kbits of EEPROM • Save critical data with Block Lock™ memory —Block lock first or last page, any 1/4 or lower 1/2 of EEPROM array • Built-in inadvertent write protection —Write enable latch —Write protect pin • SPI Interface - 3.
3MHz clock rate • Minimize programming time —16 byte page write mode —5ms write cycle time (typical) • SPI modes (0,0 & 1,1) • Available packages —8-lead TSSOP, 8-lead SOIC, 8-Lead PDIP BLOCK DIAGRAM POR and Low Voltage Reset Generation Reset & Watchdog Timebase Watchdog Transition Detector Wa...
