4kbit EEPROM; Triple Voltage Monitor With Integrated CPU Supervisor

The X40430 X40431 X40434 X40435 combines power-on reset control, watchdog Timer supply voltage supervision, second and third voltage supervision, manual reset, 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 and third 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, Intersils unique circuits allows the threshold for either voltage monitor to be reprogrammed to meet specific system level requirements or to fine-tune the threshold for applications requiring higher precision.
A manual reset input provides debounce circuitry for minimum reset component count.
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 Intersils 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 Intersils proprietary Direct Write cell, providing a minimum endurance of 100,000 cycles and a minimum data retention of 100 years.
