PT7M6126CLC4EX

PT7M6126CLC4EX is a high-performance, low power 8-bit microcontroller system-on-a-chip (SoC) designed specifically for embedded applications. As a low-power, feature-rich device, it is ideal for many applications including industrial and consumer products, medical and safety systems, home automation, energy management and many others. It is also suitable for providing background monitoring and control for a wide range of situations, from monitoring temperature and humidity in a room, to operating a motor in a production environment.

PT7M6126CLC4EX includes a built-in supervisor device, which provides users with the capability for circuit reset if voltage, temperature or system conditions go out of permissible range. This powerful supervisor device potentially provides maximum protection for the SoC from any malfunctions and unanticipated events, as well as maintaining system health. Additionally, due to its low-power operation, it consumes only minimal energy while still providing reliable performance.

Application Field

PT7M6126CLC4EX’s supervisor device provides reliable protection for embedded applications using SoC’s. Its capability makes it more robust and reliable when compared to alternative solutions, as it provides active safety monitoring throughout the system. With its 8-bit architecture, this device is suitable for a wide range of industrial, consumer and medical applications, such as household appliances, meters, personal digital assistants (PDAs), small embedded systems and automotive products.

Examples of the applications for which PT7M6126CLC4EX is suitable for include monitoring and controlling individual and group components in an embedded system, polling sensors to ensure their performance, managing memory and USB ports, providing communication functions, and — of course — working as a system reset device.

Working Principle

The supervisor device of the PT7M6126CLC4EX works through a combination of active interrupt monitoring and voltage, temperature and system parameters checking. Voltage and temperature values can be programmed beforehand, with temperature settings ranging from -40°C to +85°C and voltage settings exceeding industry norms of ±1.25V. At all times, the voltage and temperature sensors monitor any out-of-permissible variations in their afore-mentioned parameters.

Any time an alert is detected — such as an excessive voltage, temperature or system malfunction — the device sets off an interrupt signal and activates a reset, thus restoring the chips and their components in the embedded system to their default or pre-defined settings. Afterward, the device will continue monitoring and alerting at regular intervals.

The PT7M6126CLC4EX also features two different types of reset. The first is a pulse reset which activates immediately upon detection of any out-of-permissible conditions and resets the chips and components. The second is a latch reset which stays active until it manually deactivated, allowing the device to recover quickly in the case of continuous sensor alerts.
