Description
The DS1338Z-18+T&R is a low-power, serial Real-Time Clock (RTC) designed for robust and reliable timekeeping. Specifically optimized for 5V systems, this device tracks essential time data including seconds, minutes, hours, day, date, month, and year with automatic leap-year compensation. It serves as an excellent timing reference for microcontrollers and embedded processors requiring an industry-standard I²C serial interface.
Beyond its accurate clock functionality, the DS1338Z-18+ incorporates 56 bytes of battery-backed non-volatile (NV) RAM. This integrated storage provides a secure, persistent space for critical configuration parameters, event logs, or system states that must remain intact during main power cycles. Its compact SMD-8 package and low-power characteristics make it a dependable component for industrial instruments, networking equipment, and general-purpose embedded hardware.
