Description
The RS5C583 is a CMOS LSIs electronic component that serves microcomputers as a real-time clock. It provides time, calendar, and alarm functions and can be directly connected to CPUs such as 8086 and 68000. The RS5C583 is available in three different types of packages: DIP, SOP, and SSOP.
Specifications and features
- Directly connected to CPU, enabling fast access.
- 4-bit bidirectional data bus and 4-bit address bus.
- Oscillator driven by a constant voltage, ensuring stable oscillation frequency.
- Built-in timer counter using internal clock.
- Generates cyclic CPU interrupts and alarm-match interrupts.
- Interrupt flag and interrupt inhibit.
- Supports clock (hour, minute, second), calendar (leap year, year, month, day, day-of-the-week), and alarm (hour, minute) functions.
- Selectable 12- or 24-hour mode.
- Automatically recognizes leap years.
- All clock and alarm data expressed in BCD codes.
- ±30 seconds adjustment function.
- Determines whether clock data is valid or invalid.
- Low power consumption due to CMOS technology, can be backed up by batteries.
- Power supply voltage between 3.0V to 5.0V.
- Time keeping supply voltage between 2.0V to 6.0V.
- Packages: 18-pin DIP for RP5C62, 18-pin SOP for RF5C62, 20-pin SSOP for RS5C62.
Application Scenarios
The RS5C583 can be used in various applications where real-time clock functions are required. It is suitable for microcomputers that need time, calendar, and alarm functions. The direct coupling with the data buses of CPUs such as 8086 and 68000 allows for fast access and efficient performance.
