Description
The DS1302CP is an electronic component in the category of IC Chips. It is a trickle-charge timekeeping chip that includes a real-time clock/calendar and 31 bytes of static RAM. The chip communicates with a microprocessor through a simple serial interface. With the real-time clock/calendar, it provides accurate information on seconds, minutes, hours, day, date, month, and year. The clock operates in either the 24-hour or 12-hour format, with an AM/PM indicator. The DS1302CP is designed to operate on very low power, consuming less than 1μW while retaining data and clock information.
Specifications and Features
- Real-Time Clock: Counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year compensation valid up to 2100.
- Battery-Backed General-Purpose RAM: 31 x 8 battery-backed RAM for storing data.
- Serial I/O: Minimum pin count required for synchronous serial communication with clock/RAM.
- Full Operation Voltage: Supports a voltage range of 2.0V to 5.5V.
- Low Power Consumption: Uses less than 300nA at 2.0V.
- Data Transfer: Single-byte or multiple-byte (burst mode) data transfer for clock or RAM data read/write.
- Package Options: Available in an 8-pin DIP or optional 8-pin SO for surface mount.
- Simple Interface: Simple 3-wire interface for connecting with a microprocessor.
- TTL-Compatible: Compatible with TTL logic levels (VCC = 5V).
- Temperature Range: Optional industrial temperature range of -40°C to +85°C.
- DS1202 Compatibility: Successor to the DS1202 with additional features.
- UL Recognized: Underwriters Laboratories recognized for compliance with safety standards.
Application Scenarios
- Electronic devices requiring accurate timekeeping and date functionality.
- Microprocessor-based systems that need to interface with a real-time clock.
- Low-power applications that require data retention with minimal power consumption.
