The STM690SDS6F by STMicroelectronics is a highly reliable, 5-pin microprocessor supervisory circuit that ensures robust system control and protection. This compact device is designed to monitor power supply and system health, thereby providing a crucial safeguard for microprocessor systems by managing the power-on reset function and supervising the supply voltage.

Key Features

• Precision Monitoring: The device offers precise monitoring of the 3V, 3.3V, and 5V supply voltages, which is essential for systems that require consistent and reliable operations.
• Low Power Consumption: With its low power consumption, the STM690SDS6F is an ideal choice for battery-operated devices, contributing to longer battery life and efficiency.
• Watchdog Timer: The integrated watchdog timer is a fail-safe feature that resets the microprocessor in case of software lock-up, ensuring system reliability and preventing costly downtime.
• Manual Reset Input: The manual reset input allows for an external trigger to reset the system, providing additional control and diagnostic capabilities.
• Power-On Reset Generator: This feature ensures that the microprocessor starts up in a known state by generating a reset pulse upon power-up.

Applications

The STM690SDS6F is versatile and can be used in a wide range of applications, including:

• Computers and computer peripherals
• Embedded systems
• Industrial controllers
• Portable and battery-powered equipment

Technical Specifications

The STM690SDS6F is offered in a compact SO-8 package and has an operating temperature range of -40°C to +85°C. It has a voltage threshold of approximately 3.08V for the 3.3V monitored supply, which is suitable for most logic-level applications. Additionally, the device's watchdog timer has a 1.6-second timeout period, providing ample time for systems to recover from transient issues.
