MSPCF8563T

MSPCF8563x is a low-power CMOS real-time clock/calendar IC that provides a programmable clock output, an interrupt output, and a power-down detector. All addresses and data are transferred serially via the I²C bus interface. The maximum bus speed is 400kbps, and the built-in word address register increments automatically after each read/write operation.

Applications

• Portable instruments
• Mobile phones
• Fax machines
• Multi-rate energy meters
• IC card water meters
