The Analog Devices DS1302ZN+T&R is a trickle-charge timekeeping chip that manages all timekeeping functions, including seconds, minutes, hours, date, month, day of the week, and year with leap-year compensation up to 2100. It includes 31 bytes of battery-backed general-purpose RAM.
This chip interfaces with microcontrollers via a simple 3-wire serial interface (CE, I/O, SCLK) and is TTL-compatible. Data transfer can be done in single-byte or burst modes. It operates on very low power, consuming less than 300nA at 2.0V, extending battery backup run time.
The DS1302ZN+T&R is available in an 8-pin SOIC package, minimizing required space. It supports an optional industrial temperature range of -40°C to +85°C, making it suitable for a wide range of applications. The device also features dual power pins for primary and backup power supplies and a programmable trickle charger.
Key specifications include an operating voltage range of 2V to 5.5V, an operating current of 0.3µA to 1µA at 2V to 5V, and an operating temperature range of -40°C to +85°C. The package is an 8-SOIC with a width of 3.90mm. It supports both 12-hour and 24-hour time formats and a YY-MM-DD-dd date format.
It counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year compensation valid up to 2100.
It provides 31 x 8 bytes of battery-backed general-purpose RAM.
It uses a simple 3-wire serial interface.
The operating voltage range is 2V to 5.5V.
The operating temperature range is -40°C to +85°C.
It is supplied in an 8-SOIC package.
