Microchip announced its first family of real-time clock / calendar (RTCC) autonomous I2C ™. The MCP794XX six devices are highly integrated and low cost, and the wide EEPROM and SRAM, and a selection of user-lockable EEPROM for identification only 64-bit reprogrammable can be programmed at the factory with a MAC address. The devices include digital set calibration time of day and a switching function that provides battery backup power with very low levels of voltage and current. By integrating all these functions in a single device, MCP794XX family reduces component count and reduce costs in a variety of applications.
Other applications MCP794XX of thermostats are a smart consumer of energy, electricity meters and commercial refrigeration units, appliances such as stoves, dishwashers and microwave ovens, controls the dashboard in the car and car radios, as well as office equipment, controls irrigation systems, video and other consumer electronics products.
Many applications, such as cameras and laptops, they need a real time clock with power backup to maintain time and alarm settings when main power is removed. Other applications such as commercial refrigeration equipment at points of sale and security systems, they need a real time clock with a monitor in case of power failure to capture and store the time intervals when primary power fails. With its integrated battery switch circuit and recording time in case of power failure, the RTCC MCP794XX help reduce the health, safety and security of the system in applications involving the storage of perishable goods or monitoring access to secure rooms. The devices can be ordered preprogrammed with a MAC address that eliminates time-consuming step in the production flow, and digital tuning function may provide compensation software in temperature, which reduces costs compared with devices in which the temperature compensation is performed by hardware.
By submitting its first autonomous RTCC, with the RTCC integrated microcontrollers, Microchip provides customers an economical choice and a small number of pin RTCC to add functionality to their designs without significantly increasing the size or the design cost.
The availability of the daughter board RTCC MCP79410 Microchip PICtail ™ Plus (part number AC164140, $ 45) is scheduled for February 2011. The six devices are available in encapsulated MSOP, SOIC, TSSOP and 8-pin TDFN
