Product Summary
The RS5C62-E2 is a real-time clock. It is designed for battery-pack and includes serial interface functions, 8-bit timer, A/D converter, current integrator and I2C-BUS interface. And this device is available in three different types of packages: the DIP type, the SOP type, and the SSOP type. A built-in timer counter acts as a watchdog timer or interrupt timer.
Parametrics
RS5C62-E2 absolute maximum ratings: (1)Supply Voltage: –0.3 to +7.0 V; (2)Input Voltage: –0.3 to +VDD+0.3 V; (3)Output Voltage 1: –0.3 to +12.0 V; (4)Output Voltage 2 Except INTR, TMOUT:–0.3 to +VDD+0.3 V; (5)Maximum Power Dissipation TA=25°C: 300 mW; (6)Operating Temperature:–20 to +70 °C; (7)Storage Temperature:–40 to +125 °C.
Features
RS5C62-E2 features: (1)Directly connected to CPU, enabling fast access; (2)4bit bidirectional data bus, and 4bit address bus; (3)The oscillator is driven by a constant voltage, so the oscillation frequency is stable even when the power supply voltage fluctuates; (4)Built-in timer counter using internal clock; (5)Generates cyclic CPU interrupts, and generates alarm-match interrupts; (6)Interrupt flag and interrupt inhibit; (7)Clock (hour, minute, second), calendar (leap year, year, month, day, day-of-the-week), alarm (hour, minute); (8)12-or 24-hour mode is selectable; (9)Recognizes leap years automatically; (10)All clock and alarm data expressed in BCD codes; (11)+/-30 seconds adjustment function; (12)Determines whether clock data is valid or invalid; (13)Consumes very low power due to CMOS technology, so it can be backed up by batteries; (14)Power supply voltage between 3.0 to 5.0V; (15)Time keeping supply voltage between 2.0 to 6.0V; (16)Package: 18pin DIP for RP5C62, 18pin SOP for RF5C62, 20pin SSOP for RS5C62.
