STM6322SWY6F - Microprocessor Reset Circuit

The STM6322SWY6F is a sophisticated microprocessor reset circuit device designed and manufactured by STMicroelectronics, a leader in the semiconductor industry. This precision device is engineered to monitor the supply voltage of microprocessor (µP) systems, ensuring that the system resets accurately and operates reliably.

It is a highly integrated component, featuring a combination of low supply current and guaranteed reset output down to 1.0 V at the VCC input. The STM6322SWY6F is particularly suitable for battery-powered applications due to its low power consumption. Its key function is to provide a reset signal to the microprocessor during power-up, power-down, and brown-out conditions, thereby safeguarding the system against improper operation.

One of the standout features of the STM6322SWY6F is its ability to generate a reset pulse when the supply voltage drops below a preset threshold. The reset time out period is factory-set to 200 ms, which ensures proper system reset without the need for external components. The device also includes a manual reset input, which allows the system to be reset via an external push-button or logic signal.

Encased in a compact SOT-23-5 package, the STM6322SWY6F is designed with space-saving in mind, making it an excellent choice for space-constrained applications. The device operates over a wide temperature range from -40°C to +85°C, catering to a broad spectrum of commercial and industrial environments.

Key specifications of the STM6322SWY6F include:

• Supply voltage range: 2.0 V to 5.5 V
• Low supply current: 5 µA (typ.)
• Reset threshold accuracy: ±1.5%
• Factory-programmed reset timeout period
• Manual reset input
• Operating temperature range: -40°C to +85°C
