OUTLINE
The RP/RF/RS5C62 are CMOS LSIs which serve microcomputers as real-time clocks providing time, calendar, and alarm functions in direct coupling with the data buses of CPUs such as 8086 and 68000. A built-in timer counter acts as a watchdog timer or interrupt timer. They are available in three different types of packages: the DIP type, the SOP type, and the SSOP type.
FEATURES
• Directly connected to CPU, enabling fast access.
• 4bit bidirectional data bus, and 4bit address bus.
• The oscillator is driven by a constant voltage, so the oscillation frequency is stable even when the power supply
voltage fluctuates.
• 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, so it can be backed up by batteries.
• 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. -
