The ALi M5819P is a versatile Real Time Clock (RTC) and CMOS RAM converter designed for low-power system applications. It integrates a complete month-of-day clock with alarm functionality, a one hundred year calendar with leap year compensation, and a programmable periodic interrupt. The device also includes 241 bytes of general-purpose static RAM, in addition to 15 bytes dedicated to clock and control registers, providing a total of 256 bytes of RAM accessible via software.
Key features include year 2000 compliance, binary or BCD data representation, and a 12/24 hour mode with a daylight savings time option. The M5819P offers three separately software maskable and testable interrupts: a month-of-day alarm, periodic rates ranging from 122 microseconds to 500 milliseconds, and an end-of-clock update cycle. Its low power, high-speed CMOS technology makes it suitable for battery-powered applications where maintaining date and time during system power-off is crucial.
The M5819P is available in a 24-pin dual-in-line (DIP) and SOP package, suitable for through-hole or surface-mount assembly.
