This document provides information on the features of the STM6524 6-pin Smart Reset™ product. The product operates at a voltage range of 1.65V to 5.5V and has a low supply current of 1.5µA. It includes an integrated test mode and dual Smart Reset™ push-button inputs. The reset setup delay can be set from 0.5 seconds to 10 seconds in 0.5-second steps, with an option for an internal pull-up resistor. The product does not have a power-on reset and the reset output can be active low or active high, with push-pull or open drain options. It operates in a temperature range of -40°C to +85°C and is packaged in a UDFN6 package with dimensions of 1.6mm x 1.3mm.
The STM6524 is a 6-pin Smart Reset device designed to ensure system stability by preventing inadvertent resets caused by short push-button closures. It features dual Smart Reset inputs (SR0 and SR1) that require simultaneous assertion for a preset extended delay time (tgsrc) before triggering a reset output. This configuration allows the application to distinguish between software interrupts and hard system resets.
| Operating voltage | 1.65 V to 5.5 V |
|---|---|
| Low supply current | 1.5 pA |
| Reset delay range | 0.5 s to 10 s |
| Operating temperature | -40 °C to +85 °C |
| Package dimensions | 1.6 mm x 1.3 mm |
It ensures inadvertent short reset push-button closures do not cause system resets by implementing extended Smart Reset input delay time.
The processor is interrupted if push-buttons are closed for a short time, but a hard reset occurs if they remain closed for the extended setup time.
The inputs are ignored and the outputs are deasserted, with valid deasserted reset output levels down to 1.0 V.
