Renesas Electronics Corporation 1338C-18SRI is a Real Time Clock (RTC) IC from the Clock/Calendar category. This component features a 56B memory for timekeeping functions, accessible via an I2C, 2-Wire Serial interface. It supports both YY-MM-DD-dd date format and HH:MM:SS (12/24 hr) time format. Key features include leap year compensation, NVSRAM for data retention, and a square wave output. The device operates over a supply voltage range of 3.3V to 5.5V, with a separate battery voltage input from 1.3V to 3.7V. At 3.3V, the timekeeping current consumption is a maximum of 2µA. The 1338C-18SRI is supplied in a 16-SOIC package (0.295", 7.50mm Width) for surface mounting and is rated for operation between -40°C and 85°C. This component is commonly utilized in industrial and automotive applications requiring accurate timekeeping.
