STM705M6F - Microprocessor Supervisory with Battery Switchover

The STM705M6F from STMicroelectronics is a highly integrated microprocessor supervisory circuit that provides a multitude of features to enhance the reliability and proper functioning of a microprocessor system. This compact device is designed to monitor the power supply and system health of microprocessor (µP) and digital systems, ensuring that the system operates correctly even during power-up, power-down, and brownout conditions.

Key Features:

• Power Supply Monitoring: The STM705M6F offers precision monitoring of 3V, 3.3V, and 5V supply voltages, ensuring that the connected microprocessor is always operating with a stable and adequate power supply.
• Reset Output: It provides an active-low reset output that becomes active whenever VCC falls below the reset threshold, keeping the microprocessor in the reset state until VCC returns to an acceptable level.
• Battery Switchover: In the event of a power failure, the STM705M6F automatically switches to a backup battery, maintaining the power supply to volatile memory and real-time clocks.
• Low Power Consumption: Designed for energy-sensitive applications, the device features low power consumption, contributing to the overall efficiency of the system it's deployed in.
• Manual Reset Input: The inclusion of a manual reset input allows for an external signal to initiate a system reset, providing an additional layer of control.
• Watchdog Timer: An onboard watchdog timer helps to ensure that the microprocessor system does not hang in an unpredictable state by resetting the system if the watchdog is not periodically refreshed.

Applications:

The STM705M6F is a versatile component suitable for a wide range of applications, including:

• Computers and Network Equipment
• Embedded Systems
• Intelligent Instruments
• Portable/Battery-Powered Equipment

With its robust feature set and STMicroelectronics' reputation for quality, the STM705M6F is an excellent choice for designers looking to incorporate a reliable supervisory function into their microprocessor-based systems.
