Details
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.
