CSS555C Micropower Timer with Internal Timing Capacitor

The CSS555C is a micropower 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. The CSS555C device includes an internal precision timing capacitor (CTI). Its value is trimmed to 100pF ±1%.
