Rochester Electronics DS1243Y-120 Environmental and export classification status description

The Maxim Integrated DS1243Y-120 is a real-time clock (RTC) IC with integrated NVSRAM (non-volatile static random-access memory). It combines a 120-bit, time-of-day clock, calendar, alarm, and a 64Kb static RAM with a battery backup capability. The DS1243Y-120 operates with a 5V power supply and is available in a 34-pin DIP or surface mount package. Functions: 1. Real-Time Clock: The DS1243Y-120 accurately tracks time and keeps track of the current day, month, year, and day of the week. 2. Calendar Function: It provides the ability to manage dates including leap years and adjusts for the number of days in each month. 3. Alarm: The IC supports programmable alarms that can trigger at specific times or dates. 4. Non-Volatile Static RAM: The integrated NVSRAM retains data without the need for external batteries or volatile backup supplies. 5. Power-Fail Dectection: The DS1243Y-120 can detect a power failure and switch to battery backup to maintain time and data. 6. Automatic Switching: It has the ability to automatically switch between power sources based on availability. 7. Battery Backed SRAM: The IC has a 64Kb static RAM that is powered by an external battery, ensuring data retention during power loss. Applications: 1. Industrial Automation: The DS1243Y-120 is suitable for applications requiring real-time clock functionalities, such as time stamping, scheduling, and event logging. 2. Building Automation: It can be used in building management systems to manage timers, alarms, and schedules. 3. Consumer Electronics: The IC finds applications in various consumer electronics devices that require timekeeping and power-fail detection, such as TVs, audio players, and home appliances.
