Texas Instruments BQ3285ESS is a Clock/Calendar, Real Time Clock (RTC) IC featuring a 242B parallel interface. This device offers robust timekeeping with features including alarm, daylight savings, and leap year compensation. It operates within a supply voltage range of 4.5V to 5.5V, with a specific battery voltage input of 2.5V to 4V. The BQ3285ESS draws a maximum of 300µA at 5V during timekeeping. Its memory size is 242B, and it supports both YY-MM-DD-dd date and HH:MM:SS (12/24 hr) time formats. The component includes NVSRAM for data retention and provides a square wave output. Mounting is via surface mount in a 24-SSOP (0.154", 3.90mm Width) package. This RTC is utilized in industrial automation and consumer electronics applications.
