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 user’s 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 avail- able, however, Xicor’s unique circuits allows the BLOCK DIAGRAM V2FAIL WDO RESET RESET X40010/14 X40011/15 Fault Detection Register Status Register Data Register Command Decode Test & Control Logic Power on, Low Voltage Reset Generation V2MON SDA SCL VCC (V1MON) + - User Programmable Threshold Reset Logic + - VTRIP1 User Programmable VTRIP2 Watchdog Timer and Reset Logic V2MON VCC *X40010/11 = V2MON* X40014/15 = VCC • Monitor Voltages: 5V to 0.9V • Independent Core Voltage Monitor New Features Preliminary Datasheet |
