    DESCRIPTION
    This device combines four popular functions, Power-on
    Reset Control, Watchdog Timer, Supply Voltage Super-
    vision, and Block Lock 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 active for a period of
    time. This allows the power supply and oscillator to sta-
    bilize before the processor can execute code.
    The Watchdog Timer provides an independent protection
    mechanism for microcontrollers. When the microcontroller
    fails to restart a timer within a selectable time out interval,
    the device activates the RESET signal. The user selects
    the interval from three preset values. Once selected, the
    interval does not change, even after cycling the power.
    The device’s low V
    user’s system from low voltage conditions, resetting
    the system when V
    CC
     falls below the minimum V
    point. RESET is asserted until V
    proper operating level and stabilizes. Five industry
    standard V
    TRIP
     thresholds are available, however, Xicor’s
    unique circuits allow the threshold to be reprogrammed to
    meet custom requirements or to fine-tune the threshold
    for applications requiring higher precision.

    impedance state. Unless a nonvolatile write cycle is underway, the device will be in the standby 
    power mode. CS LOW enables the device, placing it in the active power mode. Prior to the 
    start of any operation after power up, a HIGH to LOW transition on CS is required. 
    Watchdog Input.
     A HIGH to LOW transition on the WDI pin restarts the Watchdog timer. The 
    absence of a HIGH to LOW transition within the watchdog time out period results in RESET 
    going active.
    Serial Output.
     SO is a push/pull serial data output pin. A read cycle shifts data out on this pin. The 
    falling edge of the serial clock (SCK) clocks the data out.
    Serial Input.
     SI is a serial data input pin. Input all opcodes, byte addresses, and memory data 
    on this pin. The rising edge of the serial clock (SCK) latches the input data. Send all opcodes 
    (Table 1), addresses and data MSB first.
    Serial Clock.
     The Serial Clock controls the serial bus timing for data input and output. The rising 
    edge of SCK latches in the opcode, address, or data bits present on the SI pin. The falling edge of 
    SCK changes the data output on the SO pin.
    Write Protect.
     When WP is LOW, nonvolatile write operations to the memory are prohibited. 
    This “Locks” the memory to protect it against inadvertent changes when WP is HIGH, the 
    device operates normally.

    Reset Output
    . RESET is an active LOW, open drain output which goes active whenever V
    falls below the minimum V
    CC
     sense level. It will remain active until V
    minimum V
    CC
     sense level for 250ms. RESET goes active if the watchdog timer is enabled and 
    CS remains either HIGH or LOW longer than the selectable watchdog time out period. 
    A falling edge of CS will reset the watchdog timer. RESET goes active on power up at about 
    1V and remains active for 250ms after the power supply stabilizes.
