Key Features
- Dual voltage detection and reset assertion -Standard reset threshold settings See Selection table on page 2. -Adjust low voltage reset threshold voltages using special programming sequence -Reset signal valid to VCC = 1V -Monitor three voltages or detect power fail
- Independent Core Voltage Monitor (V2MON)
- Fault detection register
- Selectable power-on reset timeout (0.05s, 0.2s, 0.4s, 0.8s)
- Selectable watchdog timer interval (25ms, 200ms,1.4s, off)
- Low power CMOS -25µA typical standby current, watchdog on -6µA typical standby current, watchdog off
