CSS555
Programmable 555 Timer
The CSS555 is a micro-power version of the popular 555 timer IC. It features an operating current under 5µA and a minimum supply voltage of 1.2V, making it ideal for battery-operated applications. A six-decade programmable counter is included to allow generation of long timing delays. Configuration data for the counter is held in EEPROM to maintain the standard pin count of eight. The analog circuits are temperature compensated to provide excellent stability over a wide ambient temperature range. A simple four-wire interface provides Read/Write access to the EEPROM without adding any extra pins. It is available in green, 8 pin PDIP and SOIC packages.

CSS555C
Programmable 555 Timer with Internal Timing Capacitor
The CSS555C is a micro-power version of the popular 555 timer IC. It features an operating current under 5µA and a minimum supply voltage of 1.2V, making it ideal for battery-operated applications. A six-decade programmable counter is included to allow generation of long timing delays. Configuration data for the counter is held in EEPROM to maintain the standard pin count of eight. The analog circuits are temperature compensated to provide excellent stability over a wide ambient temperature range. A simple four-wire interface provides Read/Write access to the EEPROM without adding any extra pins. The CSS555C device includes an internal precision timing capacitor (CTI). Its value is trimmed to 100pF ±1%. It is available in green, 8 pin PDIP and SOIC packages.

CSS555C-DMK
CSS555C Demonstration Kit
The CSS555C Timer IC has an internal EEPROM to store configuration and trim settings. A simple four-wire interface provides Read/Write access to the EEPROM without adding any extra pins. The Demo Kit provides a quick and easy to use tool to reconfigure the timer’s operating modes or to trim the internal timing capacitor. The configuration settings are accessed using a “point and click” dialog box. Control of the IC’s power supply and the Reset and Trigger inputs is also available under PC control. A custom PCB, which connects to a USB port, is supplied with the Demo Kit. The “Quick Installation Guide” can have you up and running in minutes. A separate operating manual provides detailed descriptions of how to use the tool. For more information, download the complete Demo Kit Operating Manual.
