WebOct 3, 2024 · The CSS555 is a Cmos 555. I do not know why a standard readily available Cmos 555 cannot be used for your project like an ICM7555, LMC555 or TLC555. With a 20M resistor and a 10uF film capacitor its timeout is almost 200 seconds. If an electrolytic capacitor is used then its leakage current might cause no timeout. WebThe analog section of the CSS555 (and CSS555C) contains a micro-power version of the standard 555 Timer. It is designed in an advanced CMOS process and includes programmable options so it can be configured to fit the intended application. Speed, power, trip levels and counter settings are stored in an internal EEPROM.

Low power, cheap, long timeout, watchdog circuit

WebIf you are using the CSS555C version of this chip, you can also adjust the value of the internal 100pf timing capacitor through this interface. To communicate with the CSS555 you send a one or two byte command via … fox news official site contact

Web(CSS555C only) are entered LSB to MSB.) If a Write command is entered, new data is loaded during the next eight clocks and it is programmed into the EEPROM during the 9 th clock pulse. The access cycle is terminated when the CONTROL pin is released. (The internal divider will pull it up to ⅔VDD and the normal timer mode will be re-established.)
