Microchip launches stand-alone I2C Real-Time Clock/Calendar family

Microchip has released its first stand-alone I2C Real-Time Clock/Calendar (RTCC) family. All six MCP794XX devices with on-chip EEPROM and SRAM, as well as a user-lockable section of EEPROM available for a 64-bit reprogrammable unique ID that can be factory-programmed with a MAC address. The devices include digital trimming for time-of-day calibration, and a battery-switchover feature that supports backup power at very low voltage and current levels.
Microchips says by integrating all of these features within a single device at a price of $0.70 each in 10,000-unit quantities, the MCP794XX family reduces component count, and lowers costs for a variety of applications.

Example applications include those in the smart-energy (e.g. thermostats, power meters and commercial refrigeration); home-appliance (e.g. stoves, dishwashers and microwave ovens); automotive (e.g. dashboard controls and car radios); and consumer-electronic markets (e.g. office equipment, irrigation controls and video systems), among others.

David Wilkie, director of Microchip's Memory Products Division says "Many applications, such as refrigeration and security systems, require a clock and alarm that operate during power-down situations. The MCP794XX family gives customers a cost-effective and low pin count option for adding this functionality to their designs without significantly increasing design size or cost."
