DESCRIPTION

The X40010/11/14/15 combines power-on reset con- trol, watchdog timer, supply voltage supervision, and secondary voltage supervision, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. Applying voltage to V CC 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.

X40010, X40011, X40014, X40015 FN8111 Rev 0.00 Page 2 of 24 March 28, 2005 Low V CC detection circuitry protects the user’s system from low voltage conditions, resetting the system when V CC falls below the minimum V TRIP1 point. RESET/RESET is active until V CC returns to proper operating level and stabilizes . A second voltage monitor circuit tracks the unregulated supply to provide a power fail warning or monitors different power supply voltage. Three common low voltage combinations are available, however, Intersil’s unique circuits a llows the threshold for either voltage monitor to be reprogrammed to meet special needs or to fine-tune the threshold for applica- tions requiring higher precision. The Watchdog Timer provides an independent protec- tion mechanism for microcontrollers. When the micro- controller fails to re start a timer within a selectable time out interval, the devi ce activates the WDO signal. The user selects the interval from three preset values. Once selected, the interval does not change, even after cycling the power. The device features a 2-wire interface and software pro- tocol allowing operation on an I 2C® bus. Dual Voltage Monitors *Voltage monitor requires VCC to operation. Others are independent of VCC.

When the V2MON input is less than the VTRIP2 voltage, V2FAIL goes LOW. This input can monitor an unregulated power supply with an external resistor divider or can monitor a second power supply with no external components.

57 S D A Serial Data. SDA is a bidirectional pin used to transfer data into and out of the device. It has an open drain output and may be wire ORed with other open drain or open collector outputs. This pin requires a pull up resistor and the input buffer is always active (not gated). Watchdog Input. A HIGH to LOW transition on the SDA (while SCL is toggled from HIGH to LOW and followed by a stop condition) restarts the Watchdog timer. The absence of this transi- tion within the watchdog time out period results in WDO going active.

X40010, X40011, X40014, X40015 FN8111 Rev 0.00 Page 7 of 24 March 28, 2005 PUP1, PUP0: Power Up Bits (Nonvolatile) The Power Up bits, PUP1 and PUP0, determine the tPURST time delay. The nominal power up times are shown in the following table. WD1, WD0: Watchdog Timer Bits (Nonvolatile) The bits WD1 and WD0 control the period of the Watch- dog Timer. The options are shown below. Writing to the Control Registers Changing any of the nonvolatile bits of the control and trickle registers requires the following steps: – Write a 02H to the Control Register to set the Write Enable Latch (WEL). This is a volatile operation, so there is no delay after the write. (Operation preceded by a start and ended with a stop). – Write a 06H to the Control Register to set the Register Write Enable Latch (RWEL) and the WEL bit. This is also a volatile cycle. The zeros in the data byte are required. (Operation proceeded by a start and ended with a stop). – Write a one byte value to the Control Register that has all the control bits set to the desired state. The Control register can be represented as qxys 001r in binary, where xy are the WD bits, s isthe BP bit and qr are the power up bits. This operation proceeded by a start and ended with a stop bit. Since this is a nonvolatile write cycle it will take up to 10ms to complete. The RWEL bit is reset by this cycle and the sequence must be repeated to change the nonvolatile bits again. If bit 2 is set to ‘1’ in this third step (qxys 011r) then the RWEL bit is set, but the WD1, WD0, PUP1, PUP0, and BP bits remain unchanged. Writing a second byte to the control register is not allowed. Doing so aborts the write operation and returns a NACK. – A read operation occurring between any of the previous operations will not interrupt the register write operation. – The RWEL bit cannot be reset without writing to the nonvolatile control bits in the control register, power cycling the device or attempting a write to a write pro- tected block. To illustrate, a sequence of wr ites to the device consist- ing of [02H, 06H, 02H] will reset all of the nonvolatile bits in the Control Register to 0. A sequence of [02H, 06H, 06H] will leave the nonvolat ile bits unchanged and the RWEL bit remains set. FAULT DETECTION REGISTER The Fault Detection Register (FDR) provides the user the status of what causes the system reset active. The Manual Reset Fail, Watchdog Timer Fail and three Low Voltage Fail bits are volatile. The FDR is accessed with a special preamble in the slave byte (1011) and is located at address 0FFh. It can only be modified by performing a byte write operation directly to the address of the register and only one data byte is allowed for each register write operation. There is no need to set the WEL or RWEL in the control register to access this fault detection register.
