Detailed Pin Configuration

The DS1232SN has the following pin configuration:

  1. GND: Ground
  2. MR: Manual Reset Input
  3. VCC: Positive Supply Voltage
  4. RESET: Active-Low Reset Output

Functional Features

  • Precision Monitoring: The DS1232SN accurately monitors the supply voltage, ensuring a reliable reset signal is generated when the voltage drops below a specified threshold.
  • Manual Reset Input: The MR pin allows for an external reset signal to be applied, overriding the internal monitoring circuitry.
  • Active-Low Reset Output: The RESET pin provides an active-low reset signal to the microprocessor or digital system, indicating that a reset condition is present.

Advantages and Disadvantages

Advantages: - Low-power consumption - Precise voltage monitoring - Compact SOIC package - Manual reset capability

Disadvantages: - Limited operating temperature range (-40°C to +85°C) - Single supply voltage range (4.5V to 5.5V)

Working Principles
