Dual Voltage Monitor With Integrated CPU Supervisor

The X40410 X40411 X40414 X40415 combines power-on reset control, watchdog Timer supply voltage supervision, and secondary voltage supervision, and Block Lock protect serial EEPROM in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.
Applying voltage to VCC activates the power on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and system Oscillator to stabilize before the processor CAN execute code.
Low VCC detection circuitry protects the users system from low voltage conditions, resetting the system when VCC falls below the minimum VTRIP1 point. RESET/ RESET is active until VCC 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, Xicors unique circuits allows the threshold for either voltage monitor to be reprogrammed to meet special needs or to fine-tune the threshold for applications requiring higher precision.
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 WDO signal. The user selects the interval from three preset values. Once selected, the interval does not change, even after cycling the power.
The memory portion of the device is a CMOS Serial EEPROM array with Xicors Block Lock protection. The array is internally organized as x 8. The device features a 2-wire Interface and software protocol allowing operation on an I2C bus.
The device utilizes Xicors proprietary Direct Write cell, providing a minimum endurance of 100,000 cycles and a minimum data retention of 100 years.
