A watchdog timer is often used in computer systems to detect when a computer is hung up and is no longer running properly. If it does become locked up and is not able to supply a reset pulse to the circuit within a defined.

A timer removes power from a circuit should a microcontroller fail to produce pulses.

In automotive microcontroller or microprocessor power-supply applications, the watchdog is used to monitor the microcontroller working status to prevent software runaway. It is necessary for the watchdog to be independent of the microcontroller in a reliable system. The TPS7B68xx-Q1 device is a family of 500-mA. . . In automotive microcontroller or microprocessor power-supply applications, the watchdog is used to monitor the microcontroller working status to prevent software runaway. It is neces.......

The Atmel sample version of the AT43USB326 contains firmware that supports customization of the Vendor ID, Product ID, String Descriptor and the keyboard matrix. This information is stored in an external AT24C02A serial EEPROM. The Atmel AT43USB326 is an 8-bit microcontroller based on the AVR RISC architecture. By exe.......

This is a battery operated Arduino project that uses the CM17A to wirelessly transmit the temperature to the power line. From there, it is picked up by the X10 Book, (see below) and displayed and logged.(It can also be used to trigger macros. )The PSC05/TW523 will not receive X10 "extended" codes. Therefore I had to get tricky with how I sent the temperature .......

Have you noticed how the blinking LED of the MacBooks causes a soothing, kind of hypnotic effect? No wonder why. . . Apparently, the behavior of the LED while the computer is sleeping is tuned to resemble the human breathing rhythm at rest! Things like these give a better understanding of Apple's meticulous attention to detail and how much of your MacBook's $999 went into patent attorne-- ALL GLORY TO THE BREATHING LED!The breathing effect is a natural step forward from the dull and classic "hel.......

PIC12F683 is a 8-pin Flash based, 8bit RISC microcontroller from Microchip. This little PIC microcontroller offers up to 6 I/O pins (the remaining two are power supply pins). It needs no external oscillator, as it has an in-built oscillator with software selectable frequency from 8 MHz to 125 KHz. It also offers a feature that allows external signals to wake it upfrom the sleep state. Here are the various features as mentioned on the datasheet. High-Performance RISC CPU:? Only 35 instructions to.......

The TPL5010-Q1 Nano Timer is a low power, AEC-Q100 qualified timer with a watchdog feature ideal for system wake up in duty cycled or battery powered applications. In such systems the microcontroller timer can be used for system wake-up, but if the timer sleep current is high, up to 60-80% of the total system. . . The TPL5010-Q1 Nano Timer is a low power, AEC-Q100 qualified timer with a watchdog feature ideal for system wake up in duty cycled or battery powered applications. In such systems the .......
