Overview
The STM6510WCACDG6F from STMicroelectronics is a dual push-button Smart Reset™ device designed to enhance system stability by preventing inadvertent short reset push-button closures from causing system resets. This device is part of the STM65xx family, which features low-current microprocessor reset circuits. The STM6510WCACDG6F is particularly useful in applications requiring delayed reset push-button responses to ensure reliable system operation.

Q & A
- What is the primary function of the STM6510WCACDG6F?
The primary function is to prevent inadvertent short reset push-button closures from causing system resets by implementing an extended Smart Reset™ input delay.
- What is the operating voltage range of the STM6510WCACDG6F?
The operating voltage range is from 1.0 V to 5.5 V.
- How is the reset pulse duration adjusted?
The reset pulse duration (tREC) is adjustable via an external capacitor (CtREC) connected to the TRECADJ pin.
- What type of package does the STM6510WCACDG6F come in?
The device comes in a TDFN8 package (2 mm x 2 mm x 0.75 mm).
- Is the STM6510WCACDG6F RoHS compliant?
Yes, the STM6510WCACDG6F is RoHS compliant.
- What is the purpose of the VCC monitoring feature?
The VCC monitoring feature asserts the reset output if the monitored supply voltage VCC drops below the specified threshold.
- How are the Smart Reset™ inputs configured?
The Smart Reset™ inputs (SR0, SR1) are active-low with internal 65 kΩ pull-up resistors and require both inputs to be held active for at least the setup delay time (tSRC) to activate the reset output.
- What is the typical supply current of the STM6510WCACDG6F?
The typical supply current is 1.4 µA.
- What are some common applications for the STM6510WCACDG6F?
Common applications include mobile phones, smartphones, e-books, MP3 players, portable navigation devices, and gaming consoles.
- How is the setup delay (tSRC) adjusted?
The setup delay (tSRC) is adjustable via an external capacitor (CSRC) connected to the SRC pin.
