This active-LOW input has an internal 70A pull-up current. It can be driven from a TTL or CMOS logic line or shorted to ground with a switch Voltage input. Ground reference for all signals Power-Fail Input - When this voltage monitor input is less than 1.25V, PFO goes LOW. Connect PFI to ground or VCC when not in use. Power-Fail Output - This output is HIGH until PFI is less than 1.25V. Watchdog Input - If this input remains HIGH or LOW for 1.6s, the internal watchdog timer times out and WDO goes LOW. Floating WDI or connecting WDI to a high-impedance tri-state buffer disables the watchdog feature. The internal watchdog timer clears whenever RESET is asserted, WDI is tri-stated, or whenever WDI sees a rising or falling edge. No Connect. Active-LOW RESET Output - This output pulses LOW for 200ms when triggered and stays LOW whenever VCC is below the reset threshold. It remains LOW for 200ms after Vcc rises above the reset threshold or MR goes from LOW to HIGH. A watchdog timeout will not trigger RESET unless WDO is connected to MR. Watchdog Output - This output pulls LOW when the internal watchdog timer finishes its 1.6s count and does not go HIGH again until the watchdog is cleared. WDO also goes LOW during low-line conditions. Whenever VCC is below the reset threshold, WDO stays LOW. However, unlike RESET, WDO does not have a minimum pulse width. As soon as VCC is above the reset threshold, WDO goes HIGH with no delay. Active-HIGH RESET Output - This output is the complement of RESET. Whenever RESET is HIGH, RESET is LOW, and vice versa. Note the SP708R/S/T has a reset output only. 1 3 1 3 1 3 VCC GND PFI 2 3 4 4 5 6 2 3 4 4 5 6 2 3 4 4 5 6 PFO 5 7 5 7 5 7 WDI 6 8 6 8 - - N.C. - - - - 6 8 RESET - - 7 1 7 1 WDO 8 2 8 2 - - R ESET 7 1 - - 8 2 Table 1.

A reset output during power-up, power-down and brownout conditions. 2. An independent watchdog output that goes LOW if the watchdog input has not been toggled within 1.6 sec. 3. A 1.25V threshold detector for power-fail warning, low battery detection, or monitoring a power supply other than +3.3V/+3.0V. 4. An active-LOW manual-reset that allows RESET to be triggered by a pushbutton switch. The SP706R/S/T devices are the same as the SP708R/S/T devices except for the active-HIGH RESET substitution of the watchdog timer. The SP706P device is the same as the SP706R device except an active-HIGH RESET is provided rather than an active-LOW RESET. THEORY OF OPERATION The SP706P/R/S/T-SP708R/S/T series is a microprocessor (P) supervisory circuit that monitors the power supplied to digital circuits such as microprocessors, microcontrollers, or memory. The series is an ideal solution for portable, battery-powered equipment that requires power supply monitoring. Implementing this series will reduce the number of components and overall complexity of a system. The watchdog functions of this product family will continuously oversee the operational status of a system. The operational features and benefits of the SP706P/R/S/T-SP708R/S/T series are described, in more detail, below. RESET Output A microprocessor's reset input starts the P in a known state. The SP706P/R/S/T-SP708R/ S/T series asserts reset during power-up and prevents code execution errors during powerdown or brownout conditions. During power-up, once VCC reaches 1V, RESET is a guaranteed logic LOW of 0.4V or less. As VCC rises, RESET stays LOW. When VCC rises above Date: 6-28-04 the reset threshold, an internal timer releases RESET after 200ms. RESET pulses LOW whenever VCC dips below the reset threshold, such as in a brownout condition. When a brownout condition occurs in the middle of a previously initiated reset pulse, the pulse continues for at least another 140ms. During power-down, once VCC falls below the reset threshold, RESET stays LOW and is guaranteed to be 0.4V or less until VCC drops below 1V. The active-HIGH RESET output is simply the complement of the RESET output and is guaranteed to be valid with VCC down to 1.1V. Some Ps, such as Intel's 80C51, require an active-HIGH reset pulse. Watchdog Timer The SP706P/R/S/T-SP708R/S/T series watchdog circuit monitors the P's activity. If the P does not toggle the watchdog input (WDI) within 1.6 seconds and WDI is not tri-stated, WDO goes LOW. As long as RESET is asserted or the WDI input is tri-stated, the watchdog timer will stay cleared and will not count. As soon as RESET is released and WDI is driven HIGH or LOW, the timer will start counting. Pulses as short as 50ns can be detected. Typically, WDO will be connected to the non-maskable interrupt input (NMI) of a P. When VCC drops below the reset threshold, WDO will go LOW independent of the current status of the watchdog timer. Normally this would trigger an NMI but RESET goes LOW simultaneously, and thus overrides the NMI. If WDI is left unconnected, WDO can be used as a low-line output. Since floating WDI disables the internal timer, WDO goes LOW only when V CC falls below the reset threshold, thus functioning as a low-line output. Power-Fail Comparator The power-fail comparator can be used for various purposes because its output and noninverting input are not internally connected. The inverting input is internally connected to a 1.25V reference.

Watchdog Timing Waveforms Manual Reset To build an early-warning circuit for power failure, connect the PFI pin to a voltage divider as shown in Figure 16. Choose the voltage divider ratio so that the voltage at PFI falls below 1.25V just before the +5V regulator drops out. Use PFO to interrupt the P so it can prepare for an orderly power-down. The manual-reset input (MR) allows RESET to be triggered by a pushbutton switch. The switch is effectively debounced by the 140ms minimum RESET pulse width. MR is TTL/ CMOS logic compatible, so it can be driven by an external logic line. MR can be used to force a watchdog timeout to generate a RESET pulse in the SP706P/R/S/T-SP708R/S/T series. Simply connect WDO to MR. VRT +3.3V VCC VRT 0V +3.3V WDO 0V tRS +3.3V tRS RESET MR* 0V +3.3V 0V *externally driven LOW tMD tMR Figure 15. Timing Diagrams with WDI Tri-stated.

High-impedance CMOS logic inputs can drift to undetermined voltages if left undriven. If a pulldown resistor is added to the RESET pin, any stray charge or leakage currents will be shunted to ground, holding RESET LOW. The resistor value is not critical. It should be about 100K, large enough not to load RESET and small enough to pull RESET to ground. Monitoring Voltages Other Than the Unregulated DC Input Monitor voltages other than the unregulated DC by connecting a voltage divider to PFI and adjusting the ratio appropriately. If required, add hysteresis by connecting a resistor (with a value approximately 10 times the sum of the two resistors in the potential divider network) between PFI and PFO. A capacitor between PFI and GND will reduce the power-fail circuit's sensitivity to high-frequency noise on the line being monitored. RESET can be used to monitor voltages other than the +3.3V/+3.0V VCC line. Connect PFO to MR to initiate a RESET pulse when PFI drops below 1.25V. Figure 17 shows the SP706R/S/T-SP708R/ S/T series configured to assert RESET when the +3.3V/+3.0V supply falls below the RESET threshold, or when the +12V supply falls below approximately 11V. Monitoring a Negative Voltage Supply The power-fail comparator can also monitor a negative supply rail, shown in Figure 18. When the negative rail is good (a negative voltage of large magnitude), PFO is LOW. By adding the resistors and transistor as shown, a HIGH PFO triggers RESET. As long as PFO remains HIGH, the SP706P/R/S/T-SP708R/S/ T series will keep RESET asserted (where RESET = LOW and RESET = HIGH). Note that this circuit's accuracy depends on the PFI threshold tolerance, the VCC line, and the resistors. Interfacing to mPs with Bidirectional RESET Pins Ps with bidirectional RESET pins, such as the Motorola 68HC11 series, can contend with the RESET output.

To correct this, connect a 4.7k resistor between the RESET output and the P reset I/O, as shown if Figure 19. Buffer the RESET output to other system components. Negative-Going VCC Transients While issuing resets to the P during power-up, power-down, and brownout conditions, these supervisors are relatively immune to shortduration negative-going VCC transients (glitches). It is usually undesirable to reset the P when VCC experiences only small glitches. Figure 20 shows maximum transient duration vs. reset-comparator overdrive, for which reset pulses are not generated. The data was generated using negative-going VCC pulses, starting at 3.3V and ending below the reset threshold by the magnitude indicated (reset comparator overdrive). The graph shows the maximum pulse width a negative-going VCC transient may typically have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e. goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically, a VCC transient that goes 100mV below the reset threshold and lasts for 40s or less will not cause a reset pulse to be issued. A 100nF bypass capacitor mounted close to the VCC pin provides additional transient immunity. Applications The SP706P/R/S/T-SP708R/S/T series offers unmatched performance and the lowest power consumption for these industry standard devices.
