The DS1302ZN+ is a real-time clock (RTC) with an integrated high-speed, SPI-compatible (Serial Peripheral Interface) serial interface. It features an integrated oscillator circuit, timer/calendar, 56-byte SRAM memory, clock burst mode, trickle-charge circuitry and an onboard crystal. The device is available in 8-pin SOIC, 8-pin DIP and 8-pin TSSOP packages. The DS1302ZN+ provides a power-management system to conserve battery life and a leap-year compensation algorithm to ensure accuracy in the leap year. The device also has an integrated power-on reset circuit, configurable address locations and can operate over a wide temperature range. It is well-suited for applications such as alarms, temperature loggers, embedded controllers, Bluetooth headsets, industrial systems and remote monitoring systems.
