Description
The RF5C62-E2 is a CMOS LSIs electronic component model that serves microcomputers as real-time clocks. It provides time, calendar, and alarm functions directly connected to the data buses of CPUs such as 8086 and 68000. It is available in three different types of packages: DIP type, SOP type, and SSOP type.
Specifications and features
- Directly connected to CPU, enabling fast access.
- 4bit bidirectional data bus, and 4bit address bus.
- Oscillator driven by a constant voltage, ensuring stable oscillation frequency even with power supply voltage fluctuations.
- Built-in timer counter using internal clock.
- Generates cyclic CPU interrupts, and generates alarm-match interrupts.
- Interrupt flag and interrupt inhibit.
- Clock (hour, minute, second), calendar (leap year, year, month, day, day-of-the-week), alarm (hour, minute).
- 12-or 24-hour mode is selectable.
- Recognizes leap years automatically.
- All clock and alarm data expressed in BCD codes.
- ±30 seconds adjustment function.
- Determines whether clock data is valid or invalid.
- Consumes very low power due to CMOS technology, making it suitable for battery backup.
- Power supply voltage between 3.0 to 5.0V.
- Time keeping supply voltage between 2.0 to 6.0V.
- Package: 18pin DIP for RP5C62, 18pin SOP for RF5C62, 20pin SSOP for RS5C62.
Application Scenarios
The RF5C62-E2 electronic component model is commonly used in microcomputers that require real-time clocks with time, calendar, and alarm functions. It can be used in various applications such as industrial automation, embedded systems, and IoT devices.
