Real Time Clocks ICs

DS1511Y Description

The DS1511Y is a highly integrated Real-Time Clock (RTC) and Calendar IC designed by Analog Devices Inc./Maxim Integrated. This device is equipped with a parallel interface and is housed in a 28-pin DIP package, making it suitable for through-hole mounting. The DS1511Y operates within a temperature range of 0°C to 70°C and is by powered a supply voltage of 4.5V to 5.5V. It also supports battery backup with a voltage range of 2.5V to 3.7V, ensuring continuous operation during power outages.

The DS1511Y features a 256-byte Non-Volatile Static Random Access Memory (NVSRAM), which provides additional storage for user data. This memory is retained even when the main power supply is disconnected, thanks to the battery backup. The device maintains time in a 24-hour format (HH:MM:SS) and includes advanced features such as an alarm, leap year compensation, square wave output, watchdog timer, and Y2K compliance.
