The STM6720SYWB6R is a state-of-the-art microprocessor reset circuit device from STMicroelectronics, designed to monitor the supply voltage of microprocessor (µP) systems. It is an essential component for reliable operation, ensuring that the µP boots up in a known state every time.

This device offers a precise monitoring system for power supplies and provides an active-low reset signal. It is particularly useful in situations where the power supply may be unstable or where it is critical that the µP does not operate below a certain voltage threshold. When the monitored power supply voltage drops below the device's threshold, the reset output is asserted (held low) until the supply voltage returns to an acceptable level and a timer has expired, ensuring the system has stabilized.

The STM6720SYWB6R features an open-drain active-low reset output, which allows for various configurations with pull-up resistors or connection to other logic inputs. This flexibility makes it suitable for a wide range of applications in different systems.

The device operates over a wide range of supply voltages, from 2.5V to 5.5V, and offers low supply current, making it an energy-efficient choice for battery-operated applications. The STM6720SYWB6R is available in a compact SOT23-5 package, which is ideal for space-constrained applications.

Key features of the STM6720SYWB6R include:

• Manual reset input
• Low supply current
• Guaranteed reset valid to Vcc = 1.0V
• 200ms typical reset pulse width
• Operating temperature range: -40°C to +85°C

With its robust design and precision voltage monitoring, the STM6720SYWB6R from STMicroelectronics is an invaluable component for ensuring the stability and reliability of microprocessor systems across a broad spectrum of industrial, consumer, and computing applications.
